摘要

“东河砂岩”从发现至今,对于其时代归属、层序顶界面位置的识别争议颇多,进而也导致了对该套砂体顶部油气藏特征及油气藏分布预测认识不清。为了分析塔里木盆地塔中地区东河砂岩段层序顶,底界面特征及其对油气成藏的控制作用,综合运用野外露头资料、岩心资料、测井以及地震资料开展了东河砂岩段层序界面的识别,剖析了东河砂岩段顶、底部不整合界面类型、分布、界面上下岩性配置关系及其对油气成藏的作用。研究表明:东河砂岩段顶、底不整合面按成因机制,可划分为5种类型;依据不同类型不整合界面上下岩性的组合,研究区目的层段共识别了23种岩性与不整合面的配置类型。并通过不整合界面对油气运聚作用进行研究,分析了已发现油气田的成藏特征。

Abstract

Since “Donghe sandstone” was found,there are lots of disputes about the age assignment and the position of the top interfaces of sequence.It is difficult to understand the characteristic of the top reservoir and predict the reservoir distribution as a result.In order to figure out the characteristic of top and back sequence interfaces of the Donghe sandstone interval and controlling process of the reservoir,this study performed analysis on the type,distribution and lithology combination of the top and back unconformity interface based on outcrop,rock core,seismic and well logging data.Research shows that,according to formation mechanism,the top and back unconformity interface could be divided into 5 types;on the basis of lithology combination,23 collocations were recognized in this area.Reservoir characteristic of gas and oil field which had been found was analyzed based on the effect of unconformity interfaces to the accumulation of oil and gas.
