First, the use of products
Well leakage is a common well in drilling engineering, and most of the drilling processes have different degrees of leakage. Serious leakage can cause the pressure drop in the well, affect the normal drilling, wellbore instability, induced formation fluid into the wellbore and blowout.
Walnut shell plugging agent in drilling, under the pressure difference, the formation of a variety of leakage to play a good sealing effect, easy to use, good compatibility, does not affect the performance of the mud.
