  • Where does the oil come from?

    For many people, drilling for oil is the same thing as drilling for water Wells: Deep underground, there is a huge liquid space filled with tens of millions of tons of oil, which can be sucked out by drilling through the formation. In fact, oil is the authentic "oil in stone", let's see what the raw material of oil looks like.

    This is called Kerogen, transliterated as kerogen, and the rock containing this material is the source rock, which is commonly called source rock or source rock, from which oil is extracted.
    The past and present lives of oil
    We know that coal comes from the remains of ancient plants, which is not controversial, because there are many coal with plant wood texture and even leaf veins and other structures. And what is oil? Everyone has seen underwater silt, which is black because it contains a lot of organic matter. The source of this organic matter is algae in the water, which are deposited on the lake bottom after they die. Given the chance to be buried quickly and cut off from oxygen, the deposited organic matter is buried under thick sedimentary rocks over long geological times. Under the high temperature and high pressure underground, their organic matter is gradually transformed into oil parent material.

    The formation of oil parent material is mostly in the early stage of sedimentation and burial, when the ground temperature is not more than 50℃. After about tens of millions of years, the deeper the sediment is buried and the higher the ground temperature (about 100-150 ° C), the maturity of the oil parent material reaches a certain range and is converted into hydrocarbons (hydrocarbons), that is, liquid oil or natural gas. Because these hydrocarbons are lighter than nearby rock, they percolate upward into the pores of the source rock formation. On the way, the oil-impervious formation is blocked and stays down, and slowly gathers in this formation, and the more and more, the formation of oil fields. So coal comes from the accumulation of plant remains, while oil is the deposition of algae, mainly from water bodies. The oil parent material in the sediment of the lake is mostly from algae, bacterial spores, pollen or resin, which mainly produces hydrocarbon petroleum of liquid paraffin. The oil parent material in Marine sediments mostly comes from plankton, algae, bacteria and a few land plants, which mainly produces liquid petroleum, supplemented by natural gas. The oil parent material in land sediments is mostly from lignin of higher plants, which is mainly used to produce natural gas. Therefore, knowing the source of the oil parent material in the source rock can predict the composition of the produced oil and the ratio of oil to gas.


     

    So the mud in the lake may turn into oil in the distant future, the carbon cycle is never broken, and new oil is always being formed. So why is oil a non-renewable resource? In fact, it is very simple, these oil are the result of hundreds of millions of years of precipitation, for us humans, the formation of oil is too long about equal to non-renewable.

    How is oil extracted
    After geological exploration, the underground reservoir is found, the location, number and depth of the well are determined, and the drilling workers will drill on the set well location. At present, the commonly used drilling technology is rotary drilling. It consists of a set of surface equipment (including drill, derrick) and a set of lifting system and drill pipe, drill tool and drill bit. Through the lifting system, the drill tool is lifted and lowered, driven by the rotation of the rotary disk, and then the drill bit is rotated to break the rock until the target layer is reached. This is the most widely used drilling method in the world.

     

     

  • The important role of mud agitator in mud tank system

     Mud agitators play a vital role in the efficient operation of mud tank systems in the oil and gas industry. These agitators are designed to keep drilling fluid, also known as mud, uniform and well-mixed, ensuring it maintains the properties required for the drilling process. The agitation process prevents solids from settling and maintains the viscosity and density of the mud, which is critical to a successful drilling operation.

     
     One of the main advantages of mud agitators is that they are compact and can be easily installed and integrated into mud tank systems. Despite their small footprint, these agitators are capable of handling drilling fluids with densities up to 20 pounds per gallon (ppg), making them suitable for a variety of drilling applications. Mud agitator power is typically available from 2.2 to 22 kilowatts, providing flexibility to meet the specific requirements of different drilling operations.
     
     Smooth operation and reliable performance of your mud agitator are critical to maintaining the overall efficiency of your mud tank system. By continuously stirring the mud, these devices prevent the formation of dead spots and ensure that the entire mud remains well mixed. This not only helps maintain the desired properties of the mud, but also enhances the performance of other equipment in the system, such as shale shakers and desanders.
     
     In addition to their primary function of mud agitation, these agitators also help prevent the buildup of gas hydrates and solids in the mud, which can cause clogging and operational problems. By keeping the mud in a consistent condition, mud agitators support the overall stability and effectiveness of the drilling process.
     
     In short, the mud agitator is an indispensable component of the mud tank system, providing efficient and reliable mixing of drilling fluids. Their compact size, small footprint and ability to handle a wide range of drilling fluids are critical to maintaining optimal performance of mud tank systems in oil and gas drilling operations.

  • VC700 Vertical Cuttings Dryer

    The VC700 Cuttings Dryer produced by Xi 'an Kosun is used to reduce the operator's total drilling fluid cost and limit the amount of waste disposal.

     

     
    The VC700 cuttings dryer is used to recover drilling fluid directly from cuttings and weight mud from the shaker mesh to avoid
    loss of weight mud due to shaker failure, rig movement or screen blockage. The VC700 cuttings dryer helps meet certain cuttings
    liquid discharge requirements and automatically controls the feed for solid-liquid separation.
    The cuttings dryer is used to recover the liquid phase drilling fluid from the cuttings by applying a high centrifugal acceleration
    force to the cuttings to improve the separation of liquid from the cuttings. The VC700 chip dryer can help save money on expensive
    drilling fluids by further purifying the expensive liquid phase that can be returned to the mud system in use.
     
     
    The VC700 cuttings dryer system recovers lost mud and returns it to the in-service mud system.
    For diesel, mineral oil and synthetic oil base mud, the recovery system can work well.
    Because it is easier to separate oil from large drill cuttings, the cuttings dryer proved to be more effective for the synthesis of oil-based mud.
    Synthetic oil-based mud systems also have a higher mud value, making the machine more attractive from an economic point of view. In addition,
    the system reduces the amount of waste and disposal costs incurred on the rig site.

  • Introduction to trenchless horizontal directional drilling

    Trenchless horizontal directional drilling (hereinafter referred to as HDD) first appeared in the 1970s, began to be introduced into China in the late 1980s,
    and developed rapidly in China at the beginning of the 21st century, widely used in the construction of electricity, telecommunications, water supply, gas, sewage, etc.,
    for the road, railway, river, hillside and other pipelines. The reason why trenchless can develop so quickly into a new industry,

    it has its own advantages: safety, speed, quality and so on. As a new industry, if we want to go further and longer, we must standardize, so sorting out and writing specifications is the focus of our work in the future.

     

    Trenchless processes: ① survey →② mechanical and personnel approach →③ excavation into drilling →④ guided crossing →⑤ excavation into drilling →⑥ back expansion →⑦ welded pipe →⑧ pipe drag out →⑨ cleaning the site →⑩ mechanical exit. All processes do not mention the use of mud, but it is like human blood, silently running through the entire most important links.

     

    People die without blood, and no excavation without mud is doomed to failure. There are ten trenchless processes: survey, approach, excavation into drilling, guided crossing, excavation out drilling, back expansion and welding pipe, hauling out, cleaning the site, and exit. Of these ten processes, three are the most important: guided crossing, backspreading, and pulling out.
    The engineers say the guided crossing is halfway through. But I think the key to a successful crossing depends on whether our hero behind the scenes, the mud, is applied correctly.

  • Mud treatment system is used in bridge pile foundation engineering, trenchless crossing engineering and oil drilling engineering construction

    Mud treatment system is used in bridge pile foundation engineering, trenchless crossing engineering and oil drilling engineering construction

     
    The mud treatment system is mainly used in the construction of bridge pile foundation engineering, trenchless crossing engineering, oil drilling engineering and underground tunnel shield engineering.
     
    Mud, also known as drilling fluid, is composed of liquid and clay, supplemented by additives, mainly plays the role of protecting the hole wall, carrying drilling slag out of the hole and cooling the drilling tool. In the process of drilling mud, because the drilling slag continues to enter the mud, the specific gravity, viscosity, sand content and so on change, can not meet the requirements of mud performance, it must be treated or purified, mainly for solid-liquid separation, the drilling slag in the mud is separated and discharged after recycling.

     
    Purification methods are mainly sedimentation tanks and mechanical equipment. The use of sedimentation tank treatment needs to occupy some land; The high water content of the drilling slag removed from the sedimentation tank makes the mud spill, the construction environment is harsh, and may cause environmental pollution or water pollution and other public hazards. The environmental problems brought by the mud are getting more and more attention. At present, the main mud treatment technology is vibrating screen, desander, desander, centrifuge, etc. According to the occasion of mud treatment, the composition of drilling slag and the requirements of mud performance, different process combinations are adopted.
