Potassium Formate is mainly used in oil drilling and widely used in the oil field as well as drilling fluid, completion fluid and workover fluid with excellent performance.
In the late 1990s, potassium formate was applied to drilling and completion fluid, especially in high-density drilling and completion fluid system.
The preparation of drilling fluid system with potassium formate has the advantages of strong inhibition, good compatibility, environmental protection and reservoir protection.
The field application results show that potassium formate has a strong ability to restrain the hydration and dispersion expansion of clay, the returned cuttings are in the shape of small round particles, the inside is dry, the drilling fluid does not paste the vibration screen, does not run the mud, has the characteristics of strong inhibition, good water loss, good wall formation, good lubricity, and so on.
The use of potassium formate mud is conducive to improving the stability of the polymer, stabilizing the shale, reducing the damage to the rock formation, and ensuring that the drilling, completion and well maintenance are in the best working condition.
It is mainly used to prepare injection fluid for water-bearing oil Wells. It can achieve high density, maintain low viscosity, improve drilling speed and extend the service life of drill bits. It is a kind of high-quality material in the field of oil exploitation.
