摘要
【目的】为解决珠江口盆地开平西洼面临的剩余圈闭少,拓储困难等问题,对该区域成藏关键要素进行分析。【方法】基于地震成藏学,利用地震勘探技术对开平西洼的构造、烃源岩等油气成藏要素进行分析,进而预测油气藏分布。【结果】综合分析认为,开平西洼文昌组具备发育半深湖—深湖相烃源岩的条件,根据地震属性进一步刻画烃源岩分布面积可达100 km^(2)。【结论】开平西洼文昌组发育一定规模的半深湖—深湖相烃源岩,具备一定勘探潜力。
[Purposes]The main Kaiping sag in the Pearl River Mouth Basin is faced with few remaining traps and difficulties in expanding reserves.In order to find large and medium-sized oil fields and further expand the reserve scale of the Kaiping sag,it is urgent to find new exploration zones.[Methods]Based on seismic-petroleum accumulation theory,this paper analyzes the oil and gas reservoir-forming elements such as structure and source rocks in the western Kaiping sag by using seismic exploration technology,so as to predict the distribution of oil and gas reservoirs.[Findings]Based on comprehensive analysis,the Wenchang Formation in the western Kaiping sag has the conditions for the development of semi-deep lake-deep lake facies source rocks,and further characterization of the distribution area of source rocks based on seismic attributes can reach 100 km^(2).[Conclusions]The Wenchang Formation in the western Kaiping sag develops semi-deep lake-deep lake facies source rocks of a certain scale,which has certain exploration potential.
