【摘要】：構(gòu)造應(yīng)力是油氣運(yùn)移與富集的控制因素之一,古今構(gòu)造應(yīng)力狀態(tài)的研究對油氣勘探與開發(fā)具有重要意義。利用流體包裹體測溫、古地磁裂縫定向、聲發(fā)射法和微地震監(jiān)測、巖石壓縮試驗(yàn)和水力壓裂法分別對鄂爾多斯盆地馬嶺油田長7致密儲(chǔ)層古今構(gòu)造應(yīng)力進(jìn)行研究。結(jié)果表明:長7致密儲(chǔ)層裂縫發(fā)育關(guān)鍵期為燕山運(yùn)動(dòng)Ⅳ幕,其水平最大主應(yīng)力方向?yàn)?4°,有效應(yīng)力大小為44 MPa;現(xiàn)今水平最大主應(yīng)力方向?yàn)?6°,而現(xiàn)今水平最小主應(yīng)力有效應(yīng)力大小為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，
