Desc:Drilling fluid is an indispensable and important part of oil drilling engineering. On the one hand, it is related to safe, fast and high quality drilling, on the other hand, it is related to reservoir protection. The effects of potassium formate drilling fluid on drilling fluid can be summarized as follows: protecting borehole wall, balancing formation earth pressure, cooling and lubricating drilling tools, providing bottom hole power, hydraulic rock breaking and returning bottom hole samples. But can potassium formate drilling fluid meet the six major trends of oil and gas exploration?
