Coal tar pitch as asphalt powder is a multifunctional organic drilling fluid treatment agent that can block leaks, prevent collapse, lubricate, reduce resistance, and inhibit drilling;

Lubrication reduces drag, reduces the lifting capacity and torque of drilling tools, prolongs the service life of drill bits, and prevents and relieves stuck drilling;

Form thin and tough mud cakes to strengthen the wellbore wall. Control high-temperature dehydration;

1、 Control the high-temperature shear strength of the mud; It can be used in combination with other mud treatment agents. It is a type of adhesive that can be used as a binder for cement and mortar in oil fields. It can increase the strength and wear resistance of mortar, provide adhesive properties of cement slurry, and thus increase the stability of oil well walls and pipelines.

2、 Coal tar pitch can also be used as an additive to improve drilling fluid viscosity and control well temperature in oil well cement cementing. The high viscosity and high-temperature resistance of coal tar pitch can maintain the stability of drilling fluid in high-temperature environments, ensuring the effectiveness of cementing.

3、 Coal tar pitch can also be used as an additive for oil well water flooding agents. It can reduce sediment and oil scale in oil well pipelines, and improve oil well production and fluidity.

4、 Coal tar pitch has various functions in oilfield additives, including binders, viscosity enhancers, lubricants, etc., which can improve drilling efficiency and oil well production efficiency, ensuring the stability and fluidity of oil wells.
