Daily Regular Maintenance

It includes thorough examination and clean-up. The suggested procedures are like below:

Check if the entrance sleeve for feeder is leaking and tighten it according to requirements. Wash away the deposits generated during its working from its inner wall and screens by water supply hose in each shift since these deposits will increase load on shock absorber and lower shaker;s ability to separate solids. Besides, examine the tensioning situation and working state of screen according to related requirements in each shift. In order to prevent solid phase from losing, connection between screen and screen frame base should be firm and stable and no hole or failure be found on screen. When screens fail, they should be replaced promptly.

Examine if horizontal support, supporting bar and lateral support deteriorate or are damaged in each shift since if they fail, screens will be destroyed. Every time when screens are replaced, check if tensioning system deteriorates or is damaged. Tensioning system is used to tension screen with tensile force and to securely fix it on screen frame base. Improper tensioning of screen will reduce its service life.

3.The equipment is covered with corrosion-explosion coating which will extend its life span when dealing with corrosive gas.

Installation and Maintenance of Liquid/Gas Separator

Installation

Generally speaking, the Liquid/Gas Separator is installed on the ground next to No.1 mud tank. The ground should be flat and sturdy and pre-dug with anchor bolt holes. For installation, hoisting machine should be used to lift the separator by its lifting lug perpendicular to the ground and put it down gently. Then tension its upper body with ground by means of steel cable and make sure it is perpendicular to the ground. Afterwards, cast anchor bolts and tighten the separator.

When it is completed, take discharge line(No.1) to where it is 60-80 meters away from wellhead(lines should be prepared by yourselves, or make it clear when making an order if lines are needed). Connect (No.2)stock inlet with rotary blowout preventer or choke manifold. Close butterfly valve of (No.6)sewage outfall and open that of (No.5)stock outlet, then connect it to No.1 mud tank via pipelines. For haulage, dismount the manifold, loosen the tightened steel cable, grasp the top of machine with hoisting machine and unscrew the anchor bolts. Its ladders can function as hauling bracket.

Maintenance:

Empty the drilling fluids from equipment and wash it clean when it is used. It is forbidden to store drilling fluids in the separator since the solidified drilling mud will not be able to work normally.

Notes on CNQ100 KOSUN Desilter Assembly and Adjustment

KOSUN Desilter is the third-phase drilling fluids solids control equipment, used to separate solid particles between 15 and 44 μm in diameter. Its cones are made from polyurethane materials and have long lifespan. Desilter has a clamp structure which makes it easy to maintain.It is compact and takes up small footprint. Drilling Desilter, Drilling Desilter Cones.

Notes on CNQ100 KOSUN Desilter Assembly and Adjustment

1. Connect the stock outlet of centrifugal pump and stock inlet of desilter together with 6” rubber hose. The gas holes atop overflow pipe are used to prevent siphonage inside. Some small amount of drilling fluids will leak via them when desilter is working. However, the hole should not be blocked especially artificially, or the machine’s performance will be affected.

2. Desilter pipe manifold, whether they are inlet main line or outlet main line, are linked by flange at either end both to allow flow-in and -out of liquid. The joint of overflow main line can rotate at any angle in order to install 8” rubber hose into another compartment of mud tank. Inlet pipe and overflow pipe should form 90° angle when they are installed.

3. Screen box fixation devices should be turned on before starting desilter.

4. Desander can be adjusted via the adjustment of Centrifugal Pump outlet pressure.

5. Screens

Screen lifespan and efficiency will be greatly affected by how well screens are assembled. Try to prevent screen from being artificially damaged. Straighten the screen, or screens will be rapidly worn due to “friction” between screens and supporting strips when shale shaker is working; but they cannot be too tightened, or they will be rapidly damaged or directly torn under over great prestress.When crooked or damaged, supporting strips should be straightened and replaced.

6. Slip locking mechanism

It is aimed at locking screens and tightening winding shaft. Winding shaft can be locked by tightening slip with screw. In order to prevent the mechanism from rusting away, it is better to lubricate it with butter every time when screens are replaced.

7. Maintenance of Screens:

It is forbidden to scratch or slap them with shovel or other iron tools and hard shovel. Apply screens with different mesh based on drilling fluids performances. It is best to use screens with thinner mesh for better efficiency when it is ensured that drilling fluids will run away.

Maintenance and Keep-up

Maintenance regulations must be implemented on screen maintenance, reparation and cleanup. Failed or damaged components should be adjusted, screwed, lubricated, cleaned, replaced when accumulative working time is above 500 hours. When above 4000 hours. Tightening shaft of screen box should be examined and replaced, taper cylinders and spiral case changed and electric motor insulation property examined.

China Development Leads Firms Abroad

On October 15th, the 114th Canton Fair which is also known as China Import and Export Fair was opened in China Import and Export Fair Complex located in Guangzhou, Guangdong, China. Having attracted 24,517 enterprises worldwide, it has set up a total of 59,539 stands for this autumn session, eight more than the spring session.

These years have witnessed increasingly rapid economic development in China and much cemented relationship with its neighboring countries as well as the top economies. Many companies flocked into this over 960-square-kilometer land for more economic potentials while more and more domestic firms eyed overseas for a larger market.

Xi’an KOSUN Machinery Co., Ltd., also called KOSUN for short, is a drilling solids control company established at the early phase of reform and opening-up. In 1992, Mr Geng Zhouhou, encouraged by Deng Xiaoping’s speech made during his inspection tour in South China, founded KOSUN which grew out of Xi’an Changqing Drilling Equipment Factory and Xi’an KOSUN Oil Drilling Equipment Co., Ltd.

China Begins to Seriously Fight Pollution

Chinese people have witnessed a dozen of smoggy days after stepping into a new year. Chinese government finally began to take serious measures to fight against the “pollution monster”.

In the recent years, China has been claiming more recognition and reputation as an emerging economy, whose wing-footed development truly stunned its neighbors and some century-old world dominants. However, its speed is too fast to allow itself a stop to sometimes have a look at how the landscape has transformed alongside.

From who-knows-what time, the air we inhale and exhale has started to contain more elements which we call dust or sand in its molecular structure. People has felt it more and more difficult to breath with such. Besides, the rivers turned foul and filthy too without much possibility to see to its bottom as before, leading to an everyday occurrence of horrible sight of dead fish bodies floating along with the dirty foams on the river surface. What is more, the installed tags in gated communities no longer produce any crystal-clean water but some yellowish mixture of liquid and sand.

Discovery of “Cancer Villages” even deepened people’s fear.

Therefore, Chinese government decided to set up a network to monitor air pollution nationwide in 17 provinces. Some experts even had suspicions that kitchen cooking should also be blamed for the emission of PM2.5 into air and called for Beijing citizens to improve on that.

In September, Beijing unveiled a five-year air pollution control plan in which the city decided to fine any violator of the rule above 1 million yuan.

The industrial factories and some oil companies are also doing their bits. Take a solids control manufacturing company in Xi’an as an example. Xi’an KOSUN Machinery Co., Ltd. was established by Mr. Geng Zhonghou after Premier Deng Xiaoping made the speech in his South China tour. It has launched a new set of environmental solutions by integration of experience accumulated in oil industry, several phases of grueling development and consistent research in advanced technologies.

This solution is able to reduce the waste at its source by using solids control equipment to purify mud and separate solids at the source; dewatering the discharged waste to minimize its water content, conduct water treatment and recycling; utilizing Hi-G shale shaker and vertical cuttings dryer for further dewatering and solid-liquid separation to minimize the waste discharge; and applying solidification, biodegradation, thermal desorption and cuttings reinjection to the discharged waste for a reasonable and effective treatment on the drilling waste.

Application of Biodegradation in Drilling Waste Management

In drilling waste management, biodegradation has become one of the most favorable solutions among oil drilling companies at home and abroad due to its less expenses and the good environmental benefits it can achieve. However, different drilling environments mean applications of biodegradation vary.

Biological drilling waste treatment describes degradation and mineralization of pollutants in drilling waste by bacteria growth, reproduction and internal respiration introduction of degrading bacteria and nutrients with the introduction of degrading bacteria and nutrients. It also takes advantage of biological characteristics in practical operations such as, liquid/solid separation by means of bios and degradation by means of adding microbial flocculant.

However, the practicality of biodegradation must be taken in to consideration based on the local environmental conditions before formally deciding upon this treatment approach. "Indigenous" microorganisms, nutrition factors, humidity, hydraulic detention time, PH value, dissolved oxygen should all be factored into consideration before the implementation of biodegradation.

“Indigenous” microorganisms are intrinsic microorganisms in drilling waste which do not need introduction and is comparatively economical, but is not effective in treatment. Nutrition factors play an important role in biological growth and metabolism. Therefore, drilling waste treatment needs appropriate addition of nutrition factors. Humidity is vital for biological growth and reproduction, but certainly of no significance for drilling fluids containing large amount of water. However, temperature should be kept under control. Minimized temperature is 15 degrees centigrade and the best is 30 degrees centigrade in drilling fluids treatment. Besides, for field operation of waste management, heating and insulation measures are needed for Winter and Spring and heating and cooling for Summer and Autumn. Hydraulic detention time defines how long treated wastewater stays in bioreactor. Organic pollutants in waste drilling fluids are, to a great extent, synthetic organic macromolecules which has a larger degradation rate than the other organic pollutants in wastewater, so the chosen bacteria should have better sludge loading ability. Above all, PH value and oxygen content of drilling fluids are also important factors and basic conditions for microorganisms to survive in drilling waste.

At present, the international waste treatment primarily adopts such approaches as land cultivation method, composting method, bioreactor, microbial flocculants method, anaerobic bio-treatment method, aerobic bio-treatment method, natural treatment method(oxidation pond).

Land cultivation method means to thoroughly degrade pollutants contained in drilling waste resorting to re-cultivation. It is very popular in many US and Russia drilling waste treatment sites, but it takes ages and costs a lot and is very easily affected by environment. Compositing method mainly degrades organisms by diluting drilling waste and then adding nutrients and sawdusts to attract microorganisms, which however truly is time-consuming. Bioreactor is both costly and energy-consuming since diluted and blended drilling waste and nutrient solution are put into certain tuner for adjustment of the survival factors for microorganism in order to achieve biodegradation. Microbial flocculants method makes good use of the principles of organic flocculants to solidify drilling fluids and degrade during the process. Apart from these, some drilling companies also apply anaerobic bio-treatment method, aerobic bio-treatment method, natural treatment method(oxidation pond) to improve on biodegradation and got good achievements.
