近年来,在我国的部分油田普遍发生了一种井孔套管的变形和断错现象,因为它与注水特别是注水压力直接相关,所以称之为注水诱发事件。观察表明,变形套管伴有明显的轴线偏移,严重者完全错断,说明岩体发生了近水平的剪切位移。套变现象与注水压力的相关性为有效应力定律提供了一种新的野外证据,对诱发地震及流体在地震过程中的作用的研究也具有一定参考价值。 In recent years, a series of wellbore casing deformation and fault breaking occurred in some oilfields in our country. Because it is directly related to water injection, especially water injection pressure, it is called water injection induced event. The observation shows that the deformation casing has obvious axis deviation, and the serious one is completely wrong, which shows that the horizontal displacement of rock mass occurs. The correlation between catastrophe phenomenon and water injection pressure provides a new field evidence for effective stress law. It also has certain reference value for the study of induced earthquakes and the role of fluid in the earthquake process.
