近年来,岩性油气藏勘探占国内陆上勘探成果的近80%,岩性蔽油气藏的圈闭形成期、油气运移期及油气运移方式的研究一直是勘探工作的重点。目前油气二次运移和聚集的研究已有了很大进展,但是,油气优势运移仍是石油地质研究中的薄弱环节。本次研究,突破传统的构造找油理念,以油气运移的优势取向分析为出发点,指出油气优势运移指向区,进而指明下部勘探方向。
In recent years, the exploration of lithologic reservoirs has accounted for nearly 80% of the domestic exploration results in the field. The research on trap formation, hydrocarbon migration and hydrocarbon migration of lithologic reservoirs has been the focus of exploration. At present, great progress has been made in the research on secondary migration and accumulation of oil and gas, however, the migration of oil and gas is still the weak link in petroleum geological research. This research breaks through the traditional tectonic oil discovery concept. Taking the advantage of hydrocarbon migration as the starting point, we point out the dominant migration directions of oil and gas, and then indicate the exploration direction of the lower part.
