大庆长垣以西黑帝庙油层成藏主控因素分析与油气潜力区预测

Analysis Main Controlling Factors of Forming Reservoir and Forcast Potential Areas in west of Changyuan,Daqing

在综合分析大庆长垣以西黑帝庙油层油气成藏主控因素的基础上,认为烃源岩、砂体不是制约黑帝庙油层油气成藏的关键因素,而T2-T06、T1-T06断裂和圈闭的遮挡条件对其油气成藏起着至关重要的作用。齐家凹陷附近不发育T2-T06、T1-T06断裂,缺少油气垂向运移的通道,在该区黑帝庙油层发现工业油气藏的可能性较小;在古龙凹陷附近预测4个油气潜力区。

Base on fully studied the reservoir forming conditions of Hedimiao reservoir, find that the key factors of forming Heidimiao reservoir are not source rock and sand stone, T2--T06 and T1-T06 faults and shield condition of trap play important role in that process. Because of absence T2-T06 and T1-T06 faults, there were few channels of migration in vertical direction round Qijia sag, and the possibility of finding industry reservoir in this area is small; forecast that there 4 potential areas round Gulong sag.
