This product is a new type of oil-gas formation protective agent for drilling fluid, developed depending on the new theory of protecting oil-gas formation about drilling fluid. Its appearance is liquid.


(1)  Main ingredient: water activity controlling agent, rock surface intermediate wet controlling agent, binder, special potentiating flowback agent and microcapsule agent.

(2)  Mechanism of action: by controlling water activity of drilling fluid and active balance of formation water, it improves the wettability of rock pore surface in reservoir, reduces interfacial tension between drilling fluid and reservoir or between drilling fluid and formation natural gas, make high flowback efficiency of in-place oil and natural gas. Meanwhile, it is useful for gasification of drilling fluids filtrate and useful for water-lock removal and releasing from Jamin effect, protect from the damage of water sensitivity in reservoir.

(3)  Main character: this product has no poison, no pollution and no fluorescence. It have good compatibility with other drilling fluid additives and drilling fluids and have no influence on the performance of drilling fluid, without sparkle and thickening. It can be suitable widely for all kinds of water base drilling fluid.
