摘要
为明确辽东东地区的勘探潜力与方向,应用油气成藏综合研究技术,利用区内地质、地球物理和分析化验等资料,研究了辽东东地区的油气成藏条件。结果表明,该区具有多元供烃的油源条件、3套区域性储盖组合、多类型的圈闭条件和有利的复式输导体系,具备形成大中型油气田的有利条件;中部走滑带的东营组—馆下段构造圈闭、东部斜坡带的东营组地层圈闭、洼陷带的沙河街组岩性圈闭以及隆起区的潜山圈闭是下步勘探的有利方向。
In order to identify the exploration potential and target in eastern Liaodong Region,integrated approaches have been used to investigate the oil /gas reservoir- forming conditions in this region with geological,geophysical and testing data. The results indicate that,the region has multiple favorable conditions to provide oil source,3 sets of regional reservoir- caprock assemblages,multi- type trap conditions and favorable multi- conduction system,which imply ideal conditions to form medium or large- scale oil /gas field. Structural trap of lower Yiguan Member of Dongying Formation in the middle strike- slip belt,stratigraphic trap of Dongying Formation in the eastern slope belt,lithological trap of Shajejie Formation in sag and buried- hill trap in uplift are prospects for future exploration.
