| 摘 要： | 地震沉积学是一门新兴边缘交叉学科,它以三维地震数据为基础,结合岩心、测井等资料,通过先进的地球物理技术,对沉积微相进行精细研究。胜利油田滨682井区沙三中、下亚段以近岸水下扇、浊流和半深湖-深湖沉积为主,浊积砂是该层主要的产油砂体。为了分析该地区浊积砂的分布规律,在地震沉积学理论指导下,运用90°相位调整技术和地层切片技术对滨682井区目的层段进行了研究。研究结果认为:垂向上,滨682井区沙三下亚段的下部和上部以及沙三中亚段的下部和上部是浊积砂体发育的有利层段;在平面上,沙三下亚段沉积早期浊积砂体主要发育在研究区东南部,面积最大可达1.71 km2;沙三下亚段沉积晚期浊积砂体在东部、东南部和南部都有发育,南部浊积砂体面积较大,可达3.37 km2,东南部和东部浊积砂体面积较小,在1.61 km2左右;沙三中亚段沉积早期浊积砂体发育在研究区东北和东南,面积可达1.90 km2;沙三中亚段沉积晚期浊积砂体发育在研究区西部和东南部,面积都较小,一般为1.15km2。

| Abstract: | Seismic sedimentology is a new traverse subject which studies the sedimentary microfacies detailedly with 3D seismic data,combining with core and logging,using advanced geophysical technique.B682 borefield in Shengli oilfield mainly develops nearshore-subaqueous-fan facies,semi-deep lake and deep lake facies,and turbidite facies in the middle and lower part of Sha 3 Member,in which the turbidite sandbody is the main petroliferous sand body.For the analysis of turbidite-sand distribution,this research studie... |
