KOSUN solids control systems

In the exploration and development of coalbed methane, drilling is a necessary means. Coal seams have the characteristics of low porosity, low permeability and low reservoir pressure, and the well type of coal seam well can greatly increase the contact area between the wellbore and the coal seam. Coalbed methane recovery factor is therefore commonly used. Coal seam drilling and coal seam drilling encounter a large area, and the coal seam fissure system is developed, mechanical strength is weak, and stress sensitivity is strong, so it is easy to encounter problems in the process of drilling. Difficulties such as easy pollution. Therefore, it is necessary to harmlessly treat the drilling fluid and mud in the process of coal seam drilling. KOSUN solids control systems are required for CBM dri
