【摘要】：高家堡地区位于霸县凹陷西侧岔河集油田,对其浅层油藏的研究较为深入。为进一步拓展油气勘探领域,应向沙二、沙三段等中深层进行重点研究。在岩心描述、薄片观察的基础上,结合地震、测井及录井等资料,系统分析了霸县凹陷高家堡地区沙三上亚段滩坝沉积特征及沉积模式。研究表明:高家堡地区古近系沙三上亚段发育碎屑岩滩坝沉积,该滩坝沉积可以进一步划分为坝砂和滩砂2个沉积亚相;研究区碎屑岩滩坝的发育,主要受古地貌背景、物源供给条件和水动力条件等因素的影响;研究区的滩坝砂体为有利的储集层,主要沿水下古隆起周围分布,可借助地震解释来预测其范围。在明确研究区沉积特征的基础上,建立了研究区相应的沉积模式,分析沉积相对研究区砂体展布的控制作用,对该区进一步油气勘探开发具有重要的指导意义。
[Abstract]:Gaojiapu area is located in Chaheji oilfield in the west of Baxian sag. In order to further expand the field of oil and gas exploration, it is necessary to focus on the middle and deep layers of the second and third member of Sha. On the basis of core description and thin section observation, combined with seismic, logging and logging data, this paper systematically analyzes the sedimentary characteristics and sedimentary model of beach dam in the upper part of the S3 submember in Gaojiapu area, Baxian Sag. The study shows that the detrital rock beach dam deposits are developed in the upper member of the Paleogene sand 3 in the Gaojiapu area, which can be further divided into two sedimentary subfacies: the bar sand and the beach sand, and the development of the detrital rock beach dam in the study area is mainly due to the paleogeomorphic background. The sand body in the study area is a favorable reservoir which mainly distributes around the underwater paleouplift and can be predicted by seismic interpretation. On the basis of defining the sedimentary characteristics of the study area, the corresponding sedimentary model of the study area is established, and the controlling effect of the sediment relative to the distribution of the sand body in the study area is analyzed, which has important guiding significance for further oil and gas exploration and development in this area.
