摘要(Abstract):

在文献[1]和[2]的基础上,根据热弹性力学和渗流力学理论,进一步探讨了在压裂施工过程中,由于高压注入所产生的压力场和温度场对井底附近地应力的影响,以及如何在压裂施工中利用这种影响以提高压裂施工效果,并保护套管和水泥环。
: Based on the theories of thermal elastic and fluid flow through porous media, the effects on the pressure field and the" temperature field of earth stress caused by high pressure injection during fracture operation and how to use these effects to improve the results of fracturing and to protect the casing and cement sheath is discussed.
