Causes and solutions of drilling sticking
Sticking, also known as differential pressure sticking, is the most common sticking accident in the drilling process, accounting for more than 60% of sticking failures. Reasons for sticking: (1)The drilling string has a long static time in the well; (2) The pressure difference in the well is larg...Read more -
Why do we need to use casing centralizer?
The use of casing centralizer is an important measure to improve the quality of cementing. The purpose of cementing is twofold: firstly, to seal off the well sections that are prone to collapse, leakage, or other complicated conditions with casing, so as to provide a guarantee for the continuatio...Read more -
