The existence of everything is related. Drilling fluid is to improve drilling efficiency and reduce accidents and mining damage to the environment. Potassium formate's inhibitory properties, anti-temperature and anti-pollution properties are actually used in many places nowadays. The use of potassium formate mud is conducive to improving polymer stability, stabilizing shale, reducing damage to rock formations, and ensuring that drilling, completion, and oil wells are in optimal working conditions.

Drilling fluid is the circulating flushing medium used in the hole during drilling. The effect of the density of potassium formate drilling fluid is actually more reflected in its hydrostatic column pressure. The pressure generated on the ground mainly comes from the three aspects of collapse pressure, pore pressure, and collapse pressure. So when we are working, if the pressure is over nature, it will cause lost circulation.

Under normal circumstances, depending on the drilling method, the pressure may be greater than or less than the pore pressure. In other words, the pressure cannot be made too small to cause the well to collapse. If we can do what the following editor talks about, this situation will be effectively reduced. When using potassium formate drilling fluid, it is necessary to carry the drilled cuttings to the ground, which means that the excavated materials need to be transported out. In this way, it will not easily cause blockage, so that the situation of well collapse will gradually decrease.

After using potassium formate drilling fluid, it actually has many functions. The main effect of using it is that it will be reflected in the pressure of the hydrostatic column. To put it more simply, the pressure of the dense hydrostatic column will naturally increase, and then it will be for the well wall and bottom The pressure generated is naturally greater.

For the generated pore pressure, the pressure actually needs to be lower than the pressure entering the well in the surface fluid. If everyone does not care enough about this situation, the rupture pressure, whenever the pressure is greater than this value, the well wall will be leaked and lost circulation will occur. Potassium formate drilling fluid can also rely on the liquid column pressure to balance the air pressure, prevent blowouts, stabilize the well wall and prevent drilling collapse. This will also be of greater help to everyone who wants to maintain the well wall.
