【摘要】 对国内外地应力测试与应用工作现状进行了综合分析。论述了地应力的分布规律、地应力的矿场和岩心测试方法、地应力的计算及其在油气勘探开发中的应用等。分析了水力压裂法、井壁崩落法、声发射法等地应力测试方法的原理、应用范围及计算方法，对目前应用的测试方法中存在的问题进行了研究，并指出了进一步发展的方向及需要解决的主要问题。结合油气勘探开发的需要，对油田开展地应力研究问题提出了建议。更多还原

【Abstract】 The newest progress on in situ stress determination technique is investigated.The in situ stress distribution,test technique in laboratory and in filed, calculation and applications in petroleum exploration and development are the key concerned aspects. Test methods including hydraulic fracturing, wellbore breakout, acoustic emission (Kaiser’s effect) are analyzed. Their principle, advantage, weakness and future development were discussed. Some valuable ideas about in situ stress applications in the design of oil development program, hydraulic fracturing and refracturing, evaluation of oil abundance zone, prediction of tectonic movement related abnormal formation pressure, oriented perforating and formation fracture zone estimation are presented. Some suggestions on theoretical study and practical application of in situ stress determination are proposed.更多还原
