| Abstract: | Differential pressure pipe-sticking is one of the most common faults in directional well operations. This paper gives detail analysis of the cause, the conditions and dealing operations about pipe-sticking. In the end, the paper takes Jiujing as example to describe the dealing process and result of differential pressure pipe-sticking. It is beneficial to carry out the construction of directional well through the analysis of directional differential pipe-sticking. |
