High Temperature Modified Potato Starch
Modified potato starch is used for filtration control in all types of water base drilling fluids ranging from fresh to salt saturated waters. It has the fuction of stable borehole,improve oil well condition,prevent collapse,and good control fluid loss,it has good ability of resist high temperature and salt water.
