摘　　要：黄河口凹陷中深部储层的物性品质是影响油气勘探的重要因素,储层物性与产能的关系研究,对勘探、开发具有重要意义。文中以黄河口凹陷为例,研究其储集物性与产液的相关关系,将试油资料和物性资料相结合,运用测试法得出有效储层物性下限,检验符合率达96.7%;根据物性下限值将储层划分为有效储层和无效储层,并对有效储层进一步分类,将黄河口凹陷的中深部储层分为4类,其中,Ⅰ类储层最好,Ⅳ类储层基本无工业价值。研究成果为合理有效地评价储层的有利分布区带提供了科学依据。The physical property quality of mid-deep reservoir in Huanghekou Sag has become the main important factor influencing on oil and gas exploration in recent years. The study of relationship between reservoi, physical property and production capacity has an important meaning to exploration and development. Therefore, combined with oil test data and physical property data, and taking Huanghekou Sag as an example, this paper studies the relationship between reservoir physical property and production fluid. Using the lower limit of valid reservoir physical property obtained by testing method, the accordance rate is inspected to be 96.7%. According to this limit value, the reservoirs are divided into valid reservoirs and invalid reservoirs. Based on the valid reservoir classification, the relationship of physical property and production capacity is built. The mid-deep reservoirs of Huanghekou Sag are divided into four types. The first type is the best reservoir and the fourth type is the reservoir almost without industrial value. This stady can provide the scientific basis for reasonably and effectively evaluating the distribution zone of favorable reservoir.
