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.
Cottonseed shell is oilfield chemical plugging material in the foundation of a, is a kind of inert material, no pollution, toxic, easy to dissolve in water can be partly dissolved in acid, is a fibrous plugging agent, for larger crack leakage layer. Plugging operation is simple, less dosage, low cost.
