Geological drill pipe exploration geology how to determine the amount of drilling fluid?

Drilling fluid is needed for geological drill pipe exploration. The use of drilling fluid also requires experience to accumulate slowly. If it is used too much or too little, it will not achieve good results. It seems simple but in fact it is profound. Determining the drilling fluid formula for a well requires a lot of knowledge and experience.

Plugging Method for Casing Leakage Plugging of Outer Flat Drill Pipe

The plugging method of casing crack leakage: grouting into the well to find out the leakage layer. Lower the expansion plug into the well, slowly press down with the drill pipe, and at the same time, use the pump to deliver slurry to the well to keep the slurry surface at the wellhead.
