水压致裂地应力测量在油田开发中的应用
|
摘要
<正> 一、前言水压致裂技术起源于石油开发中的油田水压致裂强化增产方法。1957年,哈伯特(Hubert)和威利斯(Willis)从油田水压致裂技术中得到启示,创立了常规的水压致裂应力测量理论。美国的海姆森从1970年,在美国东、西部的油田进行了一系列深部应力测量。上述水压致裂应力测量是在没有套管的钻孔(简称裸眼钻孔)中进行。不仅可得到主应力值,而且通过橡胶印模器能获得破裂裂缝的方向。80年代初,为满足油田生产需
To solve the casing breaks in the oil Wells in oil field,we have done the normal hydrofracturing measurements in the oil Well by casing and obtained the stress data.That was the first time doing the normal hydrofracturing stress measurements for the oil exploitation in China.We found out that the casing breaking was related to the crustal stress state directly after analyzing the data of in—situ stress measurements.
