摘要
本文比较了从油田压裂资料获得的应力值与专门的水压致裂应力测量结果。研究结果表明,前者的最小水平主应力可以和后者的精度相当,最大水平主应力的精度略低。以长庆油田岭261—2井1985年11月15日实际压裂记录结果和吉林油田东33—35井的压裂记录为例,提出了处理油田资料的方法。
In this paper, a comparison has been made between stress values obtained from oil-field pressure fracturing data and stress measurements observed by specific hydraulic fracturing. The research result shows that, the minimum horizontal principal stress of the former would be corresponded to the accuracy of the latter, and the accuracy of maximum horizontal principal stress is somewhat lower. Taking the actual recordings from pressure fracturing on Aug. 15, 1985 in Ling-261-2 well, Changqing Oil Field and those recordings in Dong-33-35 well, Jilin Oil Field as examples, the method for processing the oil-field data is presented and the corresponding processing result is given.
