【摘要】 本项研究综合采用层序地层学、沉积学的最新理论和方法，运用地震、测井、录井、岩心等分析资料，对松辽盆地北部他拉哈-英台-大安地区黑帝庙油层的层序地层格架、沉积相进行了深入细致的分析和研究，并对有利储层及岩性圈闭进行了初步分析和预测。 研究区位于松辽盆地北部他拉哈—英台—大安地区，构造上位于大庆长垣以西古龙凹陷和龙虎泡大安阶地毗邻地区。按传统地层分层，研究层段包括嫩江组一、二、三段。从层序地层学的观点来看，这是一个完整的三级层序。 根据地震、综合录井、测井、岩心等资料，依据井间可对比的原则，研究层段的三级层序划分为三个四级层序。层序界面上便是湖进体系域，湖进体系域顶界为最大湖泛面，在岩性上表现为区域上广泛分布的油页岩段。高位域为深湖、半深湖沉积，岩性上主要为泥岩，有时可以出现进积或加积的砂体，大致相当于嫩二段。湖退体系域大致相当于嫩三段，其上部界面为沉积转换面，即由进积到加积的转换面，下部界面为湖泛面。 本文重点探讨这个三级层序的湖退体系域。依据层序地层叠加样式，湖退体系域可划分为3个准层序组，9个准层序，即上部准层序组、中部准层序组和下部准层序组，分别大致相当于已习惯应用的黑帝庙第二油层组上部的H₂¹，中部的H₂²和下部的H₂³。在此基础上，对各个准层序进行了沉积相和砂体特征的研究。把砂体展布特征和构造特征加以叠合，以此进行有利储层和圈闭的分析和预测。 研究区内收缩体系域共发现圈闭31个，其中构造圈闭10个，岩性圈闭16个，复合圈闭5个。31个圈闭中有20个圈闭经钻探、测试或试油已获工业油流，已经形成具有工业价值的油气藏。其中，其中最有利圈闭4个，有利圈闭13个，较有利圈闭14个。更多还原

【Abstract】 The latest theory and method of sequence stratigraphy and sedimentology are adopted in this paper. By using the data of seism, well logging, mud well logging and cores, the framework of sequence strata and sedimentary facies in the areas of Talaha-Yingtai-Da’an in the north of Song-Liao basin are analyzed and studied deeply, also the favorable reservoir and lithologic traps are researched and forecasted primarily.The studied area locates in Talaha-Yingtai-Da’an in the north of Song-Liao basin, and the tectonic location is in the Gulong depression and Longhupao-Da’an terrace in the west of Daqing placanticline. According to the traditional methods, the studied area can be divided into three parts. It is a whole third hierarchy sequence.According to the data of seism, mud well logging, well logging, cores and the principles of well correlation, this third hierarchy sequence is divided into three fourth-hierarchy sequences. The bottom sequence boundary is the lacustrine transgressional system tract, and the top boundary of the lacustrine transgression system tract is the maximum lacustrine flooding surface. The lithology is albert shale distributing in the whole basin. Highstand system tract is deep lake and half-deep lake sediment. The lithology is mud stone. Sometimes the sandbody of transgression and accretion can be found, equals to N2. the lacustrine retrogradational system tract equals to N3, and its upper is conversion surface , that is the surface from transgression to accretion. The bottom is lacustrine flooding surface.This paper gives emphasis to lacustrine retrogradational system tract of the third hierarchy sequence. According to the stacking patterns, the lacustrine retrogradational system tract is partitioned into three parasequence sets and nine parasequences, that is upper parasequence middle parasequence and bottom parasequence, equal to H2’ , H22 and H23. Basing on these, the sediment faces and sandbody characteristics of each parasequence are studied, overlapping sandbody distribution structural characteristics, then the favorable reservoirs and traps are analysed and forecasted.Thirty one traps are found in the shrinking system tracks, including 10 tectonic traps 16 lithology traps and 5 combination traps. 20 traps of the 31 are drilled or found industry oil stream and form commercial pools, including 4 best traps, 13 better traps, 14 good traps.更多还原
