摘要
综合利用地震、测井、录井、岩心及分析化验资料,通过综合分析和系统沉积学编图,确定了黄河口凹陷古近系东营组三段(东三段)主要发育扇三角洲、辫状河三角洲、湖泊和湖底扇。东三段下部辫状河三角洲发育于黄河口凹陷的西南部和南部,在渤南凸起的南北两侧均发育扇三角洲朵体,半深湖—深湖主要分布于西部深凹部位,在B-2断隆带南部的半深湖区发育湖底扇,绝大部分地带为滨浅湖沉积,以滨浅湖泥滩和混合滩沉积为主。东三段上部辫状河三角洲发育于黄河口凹陷的西南部、南部及D-4断隆带的南侧,仅在渤南凸起的北侧发育扇三角洲朵体,半深湖—深湖主要分布于西北次凹部位,绝大部分地带为滨浅湖沉积,以滨浅湖泥滩和混合滩沉积为主。E-1-1—F-4-1井一带继承性发育滨浅湖砂质滩坝沉积。滨浅湖砂质滩坝由含砾粗砂岩、含砾中砂岩、含砾细砂岩及中、细砂岩组成,骨架颗粒成分以石英为主,发育低角度交错层理,纹层由定向排列的砾石或暗色组分显示,纹层平直,以低角度相交。滨浅湖砂质滩坝微相区为东三段优质储集层发育区。
Based on the comprehensive analyses of seismic,wireline log and drilling data,core and analytical and testing results,integrated analyses have been carried out on the sedimentary facies of the Member 3 of Paleogene Dongying Formation and the sedimentary facies maps have been compiled.The lower part of Member 3 of Dongying Formation is dominated by fan delta,braided fluvial delta,lacustrine and sublacustrine fan facies.The braided fluvial delta of the lower part of Member 3 of Dongying Formation was developed in southwestern and northern areas of the Huanghekou Sag.The fan delta was developed in the south and north sides of the Bonan uplift.The semi-deep to deep lake was developed in the western deep sagging area and the sublacustrine fan in the semi-deep lake south of the B-2 faulted uplift belt and most areas were dominated by shore-shallow lacustrine facies including shore-shallow lacustrine muddy bank and mixed bank.During the deposition of the upper part of Member 3 of Dongying Formation,braided fluvial delta facies was developed and mainly distributed in the southwestern and southern parts of the sag and the southern side of the D-4 faulted uplift belt,fan delta was limited to the northern side of the Bonan uplift,and semi-deep to deep lacustrine facies was developed in the western deep sagging area which was dominated by shore-shallow lacustrine facies.The sandy beach bar was developed in the E-1-1 —F-4-1 well area.The sandy beach bar is composed of gravelly coarse sandstones,gravelly medium grained sandstones and medium-fine grained sandstones with the detrital grains being dominated by quartz.Low angle cross bedding was developed.The shore-shallow lacustrine sandy beach bar microfacies is the favorable facies belt for high quality reservoir development.
