  • How to Do Daily Maintenance on Vacuum Degasser?

    READ: It is necessary to install a vacuum degasser for their removal from the drilling fluids since the invading gases may impact mud properties, cause safety risks and affect the lifespan of some equipment. Vacuum degasser has found wide application in drilling fluids circulating system.

    It is necessary to install a vacuum degasser for their removal from the drilling fluids since the invading gases may impact mud properties, cause safety risks and affect the lifespan of some equipment. Vacuum degasser has found wide application in drilling fluids circulating system, forcing the gases(such as, CH4, H2S, etc.) out of entrained drilling fluids(mud) so that mud properties(including density, viscosity) are well preserved.

    Techniques to Extend Lifespan of Vacuum Degasser:

    1. When the vaccum degasser is rolling, it is necessary to check its vacuum gauge all the time and adjust vacuum degree between 0.03~0.05 to ensure the normal operation.

    2. The rotor and suction pipe inside vacuum chamber should be washed clean after the machine is used. Then cut off the electricity, unload the blind(i.e. the oval blind flange), examine the condition of parts, remove the foreign odjects and wash clean the inner wall and rotor with high-pressure water pipe.

    3. Weekly cleaning should be performed on the head cover of vacuum chamber to keep dirty stuff from blocking gas passage. The gas collector and bubble separator on head cover can be washed by clean water. While doing these, unconnect the vacuum pipelines, undo the pipeplug and gauge stand, then insert high-pressure water pipe for 3-5 mins each time.

    4. The aforementioned cleaning should be carried out every time when drilling work is completed so as to ensure the normal operation for next time.

    5. Lubricate the spindle bearing with 250-300mL grease every other month.

    6. As far as vaccum pump is concerned, its bearing should be under frequent examination to keep its temperature, after being lubricated, 15-20 degrees higher than the ambient temperature. When it is above 30℃, vacuum gauge should be watched constantly, water in gas/liquid separator replaced promtply and the water temperature kept under 35℃.

    7. In wintertime, immediately discharge the standing water inside gas/liquid separator and pump as the precautions of possible frost crack. After vacuum pump is dismantled and repaired, please note the concentricity of coupling.

     

  • Functions of Mud Agitator in Solids Control System

    READ: KOSUN WNJ Drilling Mud Agitator, as a tank equipment in solids control system consisted of reducer and explosion-proof electric motor, has got dominant application in mud mixing and concoction. It is easy to keep up, and suitable to operate in terrible outdoor working conditions.

    KOSUN WNJ Drilling Mud Agitator, as a tank equipment in solids control system consisted of reducer and explosion-proof electric motor, has got dominant application in mud mixing and concoction. It is easy to keep up, and suitable to operate in terrible outdoor working conditions. Its large agitating strength can extend to a large scale of drilling fluids and greatly reduce resisting moments when it starts. Drilling mud agitator is mainly consisted of explosion-proof electric motor, reducer, base and impeller module, with its electric motor and reducer, reducer and impeller shaft connected via solid coupling. Welded by four blades, its impeller generates turbulent motion in drilling mud to double the agitating effects. The plate surrounded by blades prevent solids from gathering together around lower blades, reduce resisting moments against blades and avoid burning the electri motor during overload startup process.

    Drilling Mud Agitator works continuously and reliably in drilling fluids to keep it even and its solid particles suspend. As a major constituent of harmful solid phase, drill cuttings should be suspended and injected into desander, desilter and centrifuge before being taken away. At the same time, useful solid phase, such as, various weighted materials (ground hematite, ground barite) and slight bentonite should also stay in even suspension to stabilize the mud density and other mud properties. Accordingly, it is required that mud agitator should work reliably and continuously if no precipitation is expected.

    Mud agitator mainly mixes and concocts drilling fluids for the purposes of stopping the solid particles from precipitating in tank circulating system and maintaining stable mud properties as well as even concoction. Agitation is very significant in accelerating the reaction, dissolution and wetting of drilling fluids materials(such as, bentonite, barite) and chemical agents. And it also enlarges the contact area of phase interface for the reason of quickening the interaction between two phases.

     

  • Solids Control Equipment to Complete Mud Circulation

    READ: Fluid circulating system has been frequently mentioned in previous passages surrounding solids control technology, and are to be more illustrated in this one. The circulaing process is completed when the drilling fluids circulates through hydrocyclone desander, mud desilter, vacuum degasser and decanter centrifuge, through the discharge manifold in solids control module to mud pump, through its water lines into the centrifugal pump.

    It is known that drilling processes are: fluid-purification process, fluid circulating process, mud dosing process, mud concocting process, mud weighting process, automatic irrigating process, etc. Amongst them, fluid circulating system has been frequently mentioned in previous passages surrounding solids control technology, and are to be more illustrated in this one.

    The centrifugal pump, arranged inside mud cabin, suctions cleaned mud with the aid of injection pump. The drilling fluids travels out under the high pressure of AC variable frequency centrifugal pump, through dual high pressure pipelines to vertical pipe valve group standing on the drill floor after the divergence via valves in mud cabin, through the double tribble, hose, upper driving device(or swivel), inner chamber of drillstring to drill bit in the well hole. Then, the high-pressure drilling fluids jets into the well bottom and carries solid phase back to wellhead via the annular space between drillstring and casing pipes, out from the horn mouth under the turntable, through the mud pipelines below drill block to the horizontal mud cabin, and through the verticle mud cabin and the treatment of shale shaker into the tank. Afterwards, the circulaing process is completed when the drilling fluids circulates through hydrocyclone desander, mud desilter, vacuum degasser and decanter centrifuge, through the discharge manifold in solids control module to mud pump, through its water lines into the centrifugal pump.

  • Efficiency Analysis on Solids Control Equipment Removing Harmful Solid Phase

    READ: It is necessary to carry out regular efficiency analysis of solids control system in drilling site in orde to improve drilling fluids properties and better manage the cost. Generally speaking, the aggregate drilling fluids consumption in a well counts 10 to 20 times the volume of a borehole.

    It is necessary to carry out regular efficiency analysis of solids control system in drilling site in orde to improve drilling fluids properties and better manage the cost. Generally speaking, the aggregate drilling fluids consumption in a well counts 10 to 20 times the volume of a borehole. That means 90% of the expenses are poured into volume and property maintenance of the additionally concocted 90% drilling fluids. However, it can give birth to remarkable economic benefits if solids control equipment is promptly adjusted to remove more “harmful solid phase”.

    The efficiency analyses conducted on different equipment show that, theoretically speaking, all of them should have been taken away, but in fact only 80-85% or even lower amount of them have been removed and 90% would have been the best. It is also shown that, by a deeper study into separation capability of various solids control equipment and size distribution in such useful solid phase as barite and harmful solid phase(low-density particles), desander and desilter are not ideal choices to treat barite-weighted drilling fluids, but the decanter centrifuge can decrease the low solid phase gradually accumulated in any type of drilling fluids.

    “Communique on Drilling Fluids Treatment Equipment” well elaborates the standard application methods and analysis approaches of various solids control equipment, for example. drilling fluids shale shaker ought to be analyzed in terms of its solids removal rate, cuttings removal rate and drilling fluids loss ratio; desander, desilter and drilling fluids decanter centrifuge ought to be analyzed in terms of solids removal percentage, low-density solid phase discharge velocity and barite discharge speed; the decanter centrifuge also need to be calculated on its barite recovery percentage, etc.

    Besides, another formula can also work on the calculation of solids control efficiency, such as, if the figures like, dilution volume per unit time, the formation volume and the max. cuttings content got from solid phase analysis are given, we can have the efficiency rate of solids control equipment.
