Solid control equipment

Solid particles in drilling fluids can be classified into two major categories: harmful solids and useful solids, among which cuttings are the most significant harmful solids. Throughout the entire drilling process, cuttings can significantly affect the physical properties of the drilling fluid, leading to an increase in its density, viscosity, dynamic shear force, water loss, mud cake thickness, abrasiveness, viscosity and flow resistance. In addition, cuttings can also cause damage to oil and gas layers, reduce the mechanical drilling rate, increase the torque of the turntable, and lead to complex downhole situations such as obstructions during drilling and lowering, stuck sticking, well leakage, and even blowouts. Meanwhile, the presence of a large amount of rock debris will also acceler

In industrial production and environmental governance, solid-liquid separation equipment is an important piece of equipment for enhancing efficiency, reducing costs and achieving green development. Solid-liquid separation technology is widely applied in fields such as oil drilling, municipal sewage treatment, mining, chemical engineering, and food processing, and is gradually becoming a must-have equipment on enterprise production lines. The core working principle of solid-liquid separation equipment is based on the mechanical characteristics of multiphase fluids. Through physical actions such as gravitational sedimentation, centrifugal force field, membrane separation, and medium screening, it achieves precise separation of solid-liquid two-phase systems. The essence of its technology lie

Drilling fluid centrifuges are indispensable equipment in oil drilling engineering. Their main function is to separate solid particles in drilling fluid to ensure the performance and quality of the drilling fluid. Selecting the appropriate drilling fluid centrifuge is of great significance in improving drilling efficiency, reducing drilling costs, and protecting the environment. I. Understand the basic types of drilling fluid centrifuges Drilling fluid centrifuges are mainly classified into the following types: Sedimentation centrifuge: It uses centrifugal force to make solid particles settle and separate in a high-speed rotating drum. Separation centrifuge: Through high-speed rotation, it separates liquids and solid particles of different densities. Filter centrifuge: Separates solids and

As a key unit of the mud purification system, the drilling fluid desander plays a cornerstone role in multiple industrial scenarios with its highly efficient solid particle separation technology.
It utilizes the principle of centrifugal force field to precisely remove sandy particles from drilling fluid that damage system performance, ensuring the reliable operation of core equipment and promoting the industrial model of resource recycling. The following are several application scenarios of drilling fluid desanders:

Amid the roar of oilfield development, drilling operations are advancing efficiently. However, the drilling waste that comes along with it has become a persistent problem plaguing the industry’s development – the traditional disposal methods are costly, environmental protection pressure follows closely, and the waste of resources is truly regrettable. How to break the deadlock? The drilling waste treatment technology developed by Xi ‘an KOSUN offers you a one-stop green solution!

The horizontal screw centrifuge mainly consists of a drum, a screw, a differential system, a liquid level baffle, a drive system and a control system, etc. It is a dedicated solid-liquid separation equipment designed in accordance with the characteristics of petroleum drilling fluid. It can complete various processes such as feeding, centrifugal sedimentation and unloading at full speed. It is mainly used for recovering barite, removing fine solids, reducing the solid content of drilling fluid, controlling the density and viscosity of drilling fluid, ensuring the performance of drilling fluid and playing an important role in rapid drilling. The LW series centrifuge separates drilling suspensions based on the principle of centrifugal sedimentation. The suspension enters the drum through the

Oil drilling, as a globally significant energy resource, faces numerous challenges during the extraction process. During the drilling process, a large amount of drilling cuttings are produced. These cuttings are usually mixed with drilling fluid. If not handled properly, it will not only cause waste of resources but also cause serious pollution to the environment. As an advanced solid-liquid separator, the vertical cuttings dryer plays a crucial role in the oil drilling industry. It can effectively process drilling cuttings, achieving the recycling and reuse of drilling fluids and the standard discharge of cuttings. It can effectively handle drilling cuttings, achieving the recycling of drilling fluid and the standard discharge of cuttings. With the continuous growth of global energy deman

The rapid development of the petroleum industry has brought about a thorny problem: oily sludge. These black pollutants produced during the processes of oil extraction, transportation and refining contain a large amount of toxic and harmful substances. They not only damage the structure and ecological functions of the soil, but also may pollute groundwater and threaten human health. The traditional incineration and landfill treatment methods are not only inefficient but may also cause secondary pollution. Facing the increasingly severe environmental protection situation, oilfield enterprises urgently need an efficient, environmentally friendly and economical solution. The hot washing process of oil sludge is an efficient and environmentally friendly technology for treating oil sludge. It a
