摘　　要：渤海湾盆地东营凹陷南坡八面河地区沙四段湖相碳酸盐岩发育,碳酸盐岩主要发育在东西两侧沙四段1、4、5砂组,不同试油井试油产量和稳产效果有差异,为明确该类型油藏油气富集高产的主控因素,优选碳酸盐岩油藏资料丰富的八面河地区,利用面12021斜井50余米相关资料,结合研究区20口油井试油数据,开展碳酸盐岩油藏特征分析。研究表明,颗粒碳酸盐岩储层表现出中高孔中渗储层;结合试油效果分析表明,储层物性、储层厚度和原油物性影响单井稳产效果,湖相碳酸盐岩展现出良好的出油能力和潜力,是八面河未来重要的勘探领域。Lacustrine carbonate rocks of the fourth member of Shahejie Formation in the southern slope of Dongying Depression,Bamianhe area,Bohai Bay Basin,are primarily developed in the first,fourth,and fifth sand groups on their eastern and western sides.Variations in test well productivity and stable production highlight the need to identify key factors controlling oil and gas enrichment and high yield in this reservoir type.Focusing on the data-rich Bamianhe area,this study analyzes over 50 meters of data from the inclined well Mian 12021 and test data from 20 wells in the area,revealing that granular carbonate reservoirs exhibit medium-to-high porosity and medium permeability.Test results indicate that reservoir properties,thickness,and crude oil properties influence stable production,positioning lacustrine carbonate rocks as a promising exploration target for Bamianhe's future.
