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.

(3) Reduce the viscosity, which is good for high-pressure injection and reduce the agitation pressure.

(4) Reduce the damage of oil and gas layers.

(5) Stabilize the performance of drilling fluid, simplify maintenance and reduce the cost of drilling fluid.

(6) Reduce the density and reduce the possibility of lost circulation.

With the increasing environmental awareness in the world and the increasingly strict environmental protection regulations, the impact of completion fluids and their waste on the environment has aroused widespread concern in the environmental protection community, the petroleum business community, and many publics at home and abroad. Environmental protection is also a new topic in the research work of the drilling and completion industry, because potassium formate is non-toxic, easily biodegradable, and will not cause pollution and harm to the natural ecological environment.
