  As we all know, mud is the blood of drilling, and mud is also the most likely to cause pollution. Drilling fluid is also an important part of petroleum drilling. The solid-free drilling fluid has the advantages of small density and low viscosity, which is beneficial to increase the drilling speed and is gradually favored. Potassium formate drilling fluid is formed in order to adapt to the technical development requirements of modern drilling. What are the advantages of   potassium formate solid-free drilling fluid ? In order to avoid the damage of the solid phase in the drilling and completion fluid, the development of a solid-free completion fluid, because it does not contain a solid phase, potassium formate solid-free drilling fluid has the following unique advantages. (1) Increase the drilling speed, extend the life of the drill bit, and shorten the production cycle. (2) Thinning the mud cake and reducing the stuck rate of differential pressure sticking and logging tools....

With the deepening of understanding of the protection of oil and gas layers, reducing the content of solid particles, especially clay particles in drilling fluids, plays an important role in preventing the clogging of the solid particles in the pores of the oil and gas layers and improving the recovery factor. The  potassium formate solid-free drilling fluid  can avoid plugging to the greatest extent and improve the productivity of the reservoir. It is also one of the tools to liberate the reservoir. The commonly used drilling fluid for drilling production wells is water-based mud, because the drilling fluid column pressure during drilling is generally greater than the formation pressure. Under the effect of pressure difference, water and clay in the drilling fluid will invade the oil and gas layer, causing various damages to the oil and gas layer. (1) Expand the clay in the production layer (2) Destroy the continuity of oil flow (3) Produce water lock effect and in...
