| 摘 要： | 重复压裂裂缝起裂和延伸机理是重复压裂研究的重点和难点,初次人工裂缝和生产诱导是应力变化的两个主要原因。研究引起垂直裂缝井重复压裂前原地应力场变化的主要因素,认为重复压裂应优先选择有潜力的未动用小层进行补孔压裂,设计时应充分考虑裂缝的长度及导流能力,以获得更大的泄油面积,使老井获得更好的增产效果。

| 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. |

| Keywords: | refracturing variation of stresses vertical fracture fracture extension |
