摘要

摘要: 东海盆地西湖凹陷西次凹渐新统花港组上段H3砂组为低孔低渗—低孔特低渗致密砂岩储层，优质储层分布成为制约开发产能的关键问题。基于岩心、测井及物性测试等资料，对该区进行了沉积微相刻画和储层物性分析，结合构造、沉积微相发育特征，对储层展开精细分级评价和优质储层预测。研究表明，H3砂组储层分布主要受构造特征、沉积微相、砂体厚度和孔渗条件四个因素影响。在综合分析各因素与含气饱和度关系的基础上，建立了受产能约束的四因子储层精细分级评价标准，把H3砂组储层划分为“甜点”储层（Ⅰ类）、中等储层（Ⅱ类）和无效储层（Ⅲ类）三种类型。优质储层预测研究区H3-3小层为可能的高产能潜力带，H3-1、H3-2和H3-4小层次之。

Abstract: The H3 sand group of the upper section of the Oligocene Huagang Formation in the western sub-sag of the Xihu Sag of the East China Sea Continental Shelf Basin is a tight sandstone reservoir with low porosity and low or ultra-low permeability. The distribution of high-quality reservoirs has become a key factor restricting productivity. Based on coring, well logging and physical property test data, the sedimentary microfacies and physical properties of the H3 sand group were studied, and a fine grading evaluation and "sweet spot" prediction were carried out. The reservoir distribution in the H3 sand group was mainly affected by four factors: structural characteristics, sedimentary microfacies, sand thickness and conditions of porosity and permeability. Moreover, on the basis of comprehensive analysis of the relationship among these factors and gas saturation, a four-factor reservoir fine grading evaluation method was proposed. The H3 sand group reservoirs were divided into three types: "sweet spot" reservoirs (type Ⅰ), medium reservoirs (type Ⅱ) and ineffective reservoirs (type Ⅲ).The H3-3 single sand layer has a great exploration potential, followed by the H3-1, H3-2 and H3-4 single sand layers.
