Sulfonated Asphalt is a kind of multifunctional organic oil drilling mud additive with the functions of plugging, collapse prevention, lubrication, drag reduction and restraining.

With the functions of lubrication and drag reduction, it can extend the use period for the drill and prevent or solve sticking. Sulfonated Asphalt can form the thin and tough mud cake to enhance the sidewall and control high-temperature water loss. It can control the high-temperature shear strength of the slurry with good compatibility and can be used with other oil drilling mud additives together.

As the sulfonated asphalt contains sulfonic acid group, the hydration is very strong, when adsorbed on the shale interface, the hydration dispersion of shale particles can be prevented to play a role in preventing collapse.At the same time, the insoluble part can fill the pore throat and crack for sealing and can cover the shale interface to improve the quality of mud cake.Sulfonated asphalt also plays a role in lubricating and reducing the high temperature and high-pressure filtration loss in drilling fluid.

1.It is a multi-functional organic drilling fluid treatment agent for plugging, preventing collapse, lubricating, reducing resistance and inhibiting.

2.lubrication drag reduction, reduce the lifting capacity of drilling tools and torque to extend the life of the bit, prevent and remove stuck drilling;

3.Form a thin and tough mud cake to strengthen the wall.Control high-temperature water loss;

4.Control the high-temperature shear strength of mud;

5.It can be combined with other mud treatment agents.Increases of 1-6% are recommended.
