摘要
阳信洼陷陡坡带砂、砾岩体非常发育,油气成藏条件较为复杂。为有效地指导油气勘探,利用地震、测井及钻井等资料,对陡坡带构造样式及沉积体系进行了深入解剖,并分析了它们与油气成藏的关系。综合研究结果表明,阳信洼陷陡坡带主要发育铲式、座墩式和阶梯式3种构造样式以及近岸水下扇与扇三角洲2种沉积体系,不同的构造样式与沉积体系组合控制了不同的油气藏类型;岩性、构造和岩性-构造油气藏是该带今后油气勘探的主要目标。
Glutenite is developed very well in steep slope belt of Yangxin Subsag.Oil-gas reservoir formation is complex.In order to guide oil-gas exploration effectively,tectonic pattern and depositional system of the steep slope belt are analyzed thoroughly according to the seismic,log and drilling data.The relations among them and hydrocarbon reservoir formation are analyzed as well.Comprehensive study shows that there are three tectonic patterns(scraper type,stand type and step type)and two deposit systems(nearshore subsea apron and fan delta) in the steep slope belt of Yangxin Subsag.Different tectonic patterns and deposit system combinations control different hydrocarbon reservoir types.Lithologic reservoirs,structural reservoirs and lithologic-structural reservoirs are the main targets on petroleum exploration in the steep slope belt in the future.
