Coal tar pitch powder used for the production of carbon electrodes, can also be used as
infiltration agent and binder and so on.
Sulfonated asphalt powder because of containing sulfonic acid,
sulfonated asphalt hydration is very strong, when adsorbed on the
interface of shale, shale hydration dispersion of particles can
prevent collapse prevention effect. At the same time, part of
insoluble in water and filling pore and fracture plugging effect,
and can be covered in the shale interface, improve the quality of
mud cake. Sulfonated asphalt in drilling fluid lubrication and
reduce the amount of high temperature and high pressure filtration
effect, 1 is a kind of leak, collapse prevention, lubrication, drag
reduction, and inhibition of multifunctional organic drilling fluid
treatment agent. 2, lubrication drag reduction, reduce drilling
tool lifting capacity and distance longer bit life, prevent and
remove sticking; 3, the formation of thin and tough mud cake
strengthen the wall. High temperature control water loss; 4,
control of mud high temperature shear strength; 5, can be used with
other mud treatment agent distribution. Recommend to add 1-6%.
