Potassium formate drilling fluid is widely used in well drilling because of its good solubility, high density, low solid phase, low viscosity and good compatibility. What are the advantages of potassium formate drilling fluid system? The factory tells you.

(1) Wetting the weighting agent with a small amount of water and adding a proper amount of glue liquid during weighting can keep the high-density potassium formate system low viscosity and low water loss.

(2) There are representative rock samples of Anjihaihe formation and tasihe formation in the southern margin of Junggar basin. The potassium formate drilling fluid prepared in the laboratory has good inhibition on them, and the drilling fluid system has good rheological property, which is suitable for the formation conditions in the southern margin of Junggar basin, and has certain practical value.

(3) Potassium formate system has strong ability of resisting calcium and solid-phase pollution, which is good for drilling complex intervals.

(4) After hot rolling at 150 ℃ for 16 hours, the performance of high-density potassium formate drilling fluid fluctuates little and has the ability of high temperature resistance.

(5) The potassium formate drilling fluid with a density of 2.62g/cm³ still has good lubricity, which is conducive to safe drilling.

High density potassium formate drilling fluid has good lubrication performance, which is of great significance to prevent complex accidents such as differential pressure sticking and safe drilling.
