歧口凹陷沙一上亚段─东营组沉积体系
|
摘要
通过对歧口凹陷钻井、测井、非地震、地震等基础资料和前人成果的系统分析,沙河街组第一段上亚段-东营组沉积相类型丰富,发育了冲积扇、扇三角洲、三角洲、水下冲积扇、湖泊相等类型。三角洲前缘河口坝、席状砂微相、深水浊积扇砂体具有较好的储集物性和良好的成藏配置条件,是形成岩性油气藏的良好场所。
According to the systemic analysis of drilling data,well log,non-seismic and seismic data,and combined with the previous research results,Member 1-S of the Shahejie Formation and Dongying Formation of Paleogene System is considered to be an integrity of second order sequence(LSC4).The result of the research on the sedimentary system indicates that several types of sedimentary facies have developed in LSC4,including alluvial fan,fan-delta,delta,underwater fan,lakes and so on.The delta front mouth bar and sheet sand microfacies and deep-water turbidite fan sand are the potential favorable areas for lithologic reservoir.Exploration practice indicates that Member 1-S of the Shahejie Formation and the Dongying Formation in the Qikou sag have a great exploration potential for oil and natural gas.
