【摘要】：构造应力是油气运移与富集的控制因素之一,古今构造应力状态的研究对油气勘探与开发具有重要意义。利用流体包裹体测温、古地磁裂缝定向、声发射法和微地震监测、岩石压缩试验和水力压裂法分别对鄂尔多斯盆地马岭油田长7致密储层古今构造应力进行研究。结果表明:长7致密储层裂缝发育关键期为燕山运动Ⅳ幕,其水平最大主应力方向为84°,有效应力大小为44 MPa;现今水平最大主应力方向为76°,而现今水平最小主应力有效应力大小为15 MPa。
[Abstract]:Tectonic stress is one of the controlling factors of oil and gas migration and enrichment. The study of tectonic stress state in ancient and modern times is of great significance to oil and gas exploration and development. Using fluid inclusion thermometry, paleomagnetic fracture orientation, acoustic emission and microseismic monitoring, rock compression test and hydraulic fracturing, the tectonic stress of Chang7 tight reservoir in Maling Oilfield, Ordos Basin, is studied. The results show that the critical stage of fracture development in Chang7 tight reservoir is Yanshanian movement 鈪，
