摘要

在胜利油田 ,深层油气勘探已经成为寻找后备储量的主要方向 ,但是因为研究程度低而未能取得重大突破。因此 ,有必要跳出既成思路 ,针对孔店组作扎实的基础研究。本文以地震地层学的观点和方法 ,把东营 -惠民凹陷孔店组的地震反射看作一个地震层序 ,并将其划分为三个亚层序 (相当于层序地层学中的体系域 ) ,分别对应于地层分层上的孔一段、孔二段和孔三段。利用地震反射波的振幅、连续性、内部结构和外部形态等地震反射特征 ,在具有油气勘探前景的孔二段的地震反射中识别出了中振幅中连续亚平行席状相、杂乱充填相、杂乱 -斜交前积相、丘状相、弱振幅中连续楔状相、弱变振幅低连续楔状相及帚状前积相等七种地震相。将地震相转变为沉积相 ,划分出了湖泊沉积环境的深湖 -半深湖、滨浅湖、扇三角洲、近岸水下扇等沉积相 ,进而预测了有利相带 ,优选了部分深湖 -半深湖相沉积区作为下一步勘探工作的重点目标区域 ,为今后的勘探工作提出了有益的建议
In Shengli Oil Field,the exploration of oil and gas in deeply buried strata has become the main direction of searching reserves,but a great breakthrough has not been made owing to the lower study degree.So it is very necessary to make a foundational study aiming at Kongdian Formation instead of old thought.In this paper,the seismic reflection corresponding to Kongdian Formation in Dongying-Huimin Sag is regarded as an integral seismic sequence from the view of seismic stratigraphy,that can be divided into three sub-sequences corresponding to the three members of the formation.According to the characteristics of seismic reflection such as amplitude,continuity,interior structures and exterior shapes,seven seismic facies,including medium amplitude medium continuity and parallel or sub-parallel sheet facies,disorderly filling facies,disorderly progradation facies,hummocky facies,weak amplitude and medium continuity wedge facies,weak-variable amplitude and poor continuity wedge facies,and broom progradation facies,are recognized from the seismic reflection corresponding to Member 2 of Kongdian Formation which is prospective for oil and gas exploration.The sedimentary facies in the lake environment,including semideep-deep lake sub-facies,shallow lake and shore sub-facies,fan-delta and subaqueous alluvial fan, etc., are identified from seismic facies.The favorable areas are identified.Some depositional areas of semideep-deep lake are found to be the important target regions.Some beneficial advices are proposed for further exploration.
