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 properties of middle and deep reservoirs in the Yellow River estuary depression are important factors that affect oil and gas exploration. The relationship between reservoir physical properties and productivity is of great significance to exploration and development. Taking the Huanghekou depression as an example, the relationship between reservoir properties and fluid production was studied. Combining test oil data with physical data, the lower limit of effective reservoir physical properties was obtained by testing method. The coincidence rate was 96.7% The lower limit divides the reservoir into effective reservoir and ineffective reservoir, further classifies the effective reservoirs, and divides the middle and deep reservoirs of the Yellow River Estuary into four types, among them, Class I reservoirs are the best, Class IV reservoirs Layers have almost no industrial value. The research results provide a scientific basis for evaluating the favorable distribution of reservoirs reasonably and effectively.
