How about the cementing quality of potassium formate drilling fluid?
Since the beginning of this year, in the face of unfavorable factors such as deep well depth, high pressure, and large temperature difference in the southwestern work area, requirements for the lubrication of drilling fluid, wellbore stability and wellbore cleaning capabilities are extremely high. In drilling operations, there are generally at least two cementing (production wells) and as many as 4 to 5 cementing (deep exploratory wells). Potassium formate is a new type of drilling fluid at present. It does not paste the vibrating screen or run the slurry when drilling. It has strong inhibition, good wall-building properties, good lubricity, fast mechanical drilling speed, low cost, and good cementing effect. And other features are widely used. Purpose of using potassium formate drilling fluid for cementing: 1. Potassium formate drilling fluid can isolate complex formations that are easy to collapse and lose, consolidate the drilled wells, and ensure the smooth progress of drilli
