Product Uses:
It is mainly used to prepare water-bearing oil well filling fluid, and potassium formate began to be applied to drilling and completion fluid in the late nineties, especially in high-density drilling and completion fluid system, and achieved good results. The drilling fluid system prepared with potassium formate has outstanding advantages such as strong inhibition, good compatibility, environmental protection and oil layer protection. The field application results showed that potassium formate inhibited clay hydration.
