辽河盆地桃园—大平房地区东营组沉积储层特征研究
|
摘要
桃园-大平房地区位于辽河盆地东部凹陷中央断裂背斜构造带南段。该区紧临富油气生烃洼陷,具有丰富的油气资源。经过多年的油气勘探,在该区已发现沙一段、东营组、馆陶组及上第三系明化镇组等多套含油气层系。但东营组只探明了气储量,始终未能探明规模石油地质储量。因此该区东营组是今后油气勘探的重点层系。
本论文以东营组为研究对象,充分利用岩心、钻井、录井、测井及地震资料,进行全区地层对比,建立精细层序地层学格架;在此基础上,研究不同沉积时期的古地理、相带展布及沉积演化进程;选取相应的分析化验手段对储层储集特征进行描述,研究其成岩作用及孔隙演化特征;在综合分析的基础上,对储层储集性能进行评价,预测有利储层发育区。
通过本论文研究取得了以下几点认识:
1.将桃园—大平房地区东营组划分为三个层序;
2.指出该区沉积相类型有扇三角洲前缘、滨浅湖、河流相等,主要发育两种沉积体系:扇三角洲前缘—滨浅湖相沉积体系和河流相沉积体系;
3.结合储层物性、孔隙结构、沉积和成岩特征,评价出三类有利储层;
4.指出该区存在三个有利勘探领域:Sq1扇三角洲前缘相带、Sq2主河道砂体、Sq3主河道砂体。
Taoyuan-Dapingfang region lies in the south of central fault-anticline structure zone belonged to the east depression in Liaohe basin, which is adjacent to abundant hydrocarbon resource sag. Through many years' exploration, four gas-oil groups in Es_1, Ed, Ng, Nm have been discovered. But in E_d only natural gas has been proved, and petroleum reservoir has not been broke through all along. So Ed in the region will become into gas-oil exploring important formation.In the paper E_d is study object. Through the comprehensive analysis of core, drilling, logging, seismic data, stratigraphic correlation in the region has been finished, and fine sequence stratigraphic framework has been established. Furtherly, paleogeography, distribution of facies belts and sediment development of every sedimentary phase have been studied. Based on analysis and assay data, reservoir feature was characterized, and diagenesis and pore developing was described. By comprehensive analysis, reservoir capability has been valuated, and favorable reservoir areas have been predicted, and more short-range exploration target have been pointed out.Major results include as the following:1. Sequence stratigraphic feature of Taoyuan-Dapingfang region has been analyzed systematically, furthermore three medium-term cycle have been divided into.2. Pointed out that sedimentary facies in the region is fan-delta, shore shallow, fluvial facies, and that there are two sediment bodies: one is made of the frontal of fan delta and shore shallow;another is fluvial facies.3. Based on reservoir physical properties, pore structure, sediment feature, diagenesis,three favorable reservoir have been valuated.4. Three favorable exploration region have been directed: the frontal of fan delta in Sq1,and channel sandrock body in Sq2, and channel sandrock body in Sq3.
