摘要
通过对莺东斜坡带历年油气勘探成果的回顾,剖析了天然气运聚成藏条件及主控因素,指出了近期油气勘探新领域.莺东斜坡带近期油气勘探首先要开拓下第三系披覆构造-古潜山圈闭带的勘探;其次要加强对斜坡带中、南段中新统地层岩性圈闭的综合研究,攻克地层岩性圈闭封堵有效性研究难关,优选出最佳勘探目标进行钻探,以期获得突破;另外,还要重视油气苗及"气烟囱"发育区的勘探与研究工作,开辟斜坡带油气勘探的后备战场.
Based on a review of the oil and gas exploration history in Yingdong slope area, Yinggehai Basin, conditions and main controls of natural gas migration and accumulation are analyzied, and some new traps for current exploration are pointed out. The Paleogene drape buried hill trap should be probed firstly, and then a comprehensive research into Miocene stratigraphic lithologic traps have to be strengthened in the central and south parts of the slope area, by which seal availability of these traps can be revealed, leading to selecting of the most favorable prospects for drilling. Furthermore, oil and gas seepages and 'gas chimney' should also be surveyed and studied in the area.
