| 摘 要： | 从储层沉积学的角度,对冷东-雷家地区沙河街组砾质扇三角洲的沉积特征、成岩作用与油气储集性能的关系进行了深入的研究.文中重点阐述了扇三角洲前缘岩石相及“复模态”岩石结构对油气储集性能的控制作用,并对各种成岩-储集相的孔隙演化史及其储集特征进行了研究,从储层成因机理的角度,指出了有利储集砂体的发育规律,从而为研究区的油气勘探评价及开发准备阶段有利钻探区的确立提供了重要的地质依据.

| Abstract: | This paper discussed the sedimentology,diagenesis and their influence on petrophysical properties of gravel fan deltas in Shahejie forrnation in Lengdong-Leijia region,Liaohe oil-field for examining the distribution of reservoir and their evaluationg thereservoir quality.The controlling effect of lithofacies and "complex pattern" of rock texture on petrophysicalpreoperties was studied.According to the diagenetic features and their effect on pores of rocks,a concept of diagenesis-reservoir facies was proposed and the evolution history ofpores and petrophysical properties in each diagenesis-reservior facies was discussed in detail.Finally,the development law of favorable reservoir sandbody was studied.This research result provides an important basis for determining of the favorable drilling region inexploration the preparation. |
