垂直裂缝井重复压裂前原地应力场变化研究
On the Change of the Stress before the Refracture
摘要
Abstract
The cracks and extension of refracture is the important and difficult part of the stress study.The two main reasons for stress changes are caused by cracks and production.This paper mainly researches the cause of vertical crack refracture.The design based on the principle of cracks in the length and diverting capacity can bring more oil and get more output from the old wells.关键词
