本文通过对坨1井高台子油层单层细分相研究,发现该层油气主要聚集在主河道与分流间泥岩相之间的次河道相带内,是油气二次运移所形成的残余岩性油气藏,在次河道相带中还有找油气的远景,从而使这个经过多次勘探没有发现油气田的老区(双坨子地区)有可能变成寻找隐蔽油气藏较有远景的新区。 Based on the study of the single-layer subdivision facies of Tuotai-1 well in Gaotaizi reservoir, it is found that the oil and gas mainly accumulate in the secondary channel facies between the main and mudstone facies, and are the residual rocks formed by secondary migration of oil and gas There is also the prospect of looking for oil and gas in the sub-channel facies so that this old area (Shuangtuozi area) that has not been discovered through multiple exploration may turn into a new area with more prospects for finding hidden oil and gas reservoirs.
