| 摘 要： | 在野外地质调查、平衡剖面分析的基础上, 结合区域构造演化, 采用岩石声发射法对雪峰隆起西南缘的最大古应力进行了恢复, 并探讨了古应力大小与油气成藏破坏的关系。研究结果表明, 研究区共经历了5期不同强度的重要构造变革运动。在早古生代末期和印支期构造运动较弱, 声发射法的测量表明古应力值分别为13.3 MPa和24 MPa, 对应于麻江古油藏的主要成藏期。构造运动次数较多或者古应力值较大的时期, 主要对应于麻江古油藏储集层的发育期和油藏大规模破坏期。晚古生代末期构造活动次数较少, 但恢复地古应力值较大, 为92.6 MPa; 燕山期和喜马拉雅期经历了多期构造活动, 恢复地古应力值为23.3~74.4 MPa。

| Abstract: | Based on the geological survey,balanced cross-section analysis and regional tectonic evolution,we take advantage of rock acoustic emission information to restore the maximum paleo-stress in the southwest margin of Xuefeng Uplift,and discuss the relationship between the maximum paleo-stress and hydrocarbon accumulation and damage.The results show that the study area has undergone five key structural reforms of different intensities.In the early Paleozoic and Indosinian cycle,the tectonic movement is weak,and... |
