Use scope
Because preparing sulphonated asphalt powder contains sulfonic acid,hydration role strong,when the adsorption in the shale interface,can prevent shale particles scatter hydration prevent collapsed.While,insoluble in waterpartial can fill pore and crack have seal of role,and can covered in shale the interface,to improve the quality of mud cake;preparing sulphonated asphalt powder in the drilling fluid still can rise lubrication and reduce high temperature and high pressure filtration the loss, is a kind of sealing, prevent collapse, iubrication, drag reduction, restrain etc. multi-functional organic drilling fluid of finishing agent. Recommend quantity is 1-4%.
