罗家地区砾岩体储集层分类综合评价

砾岩体油气藏是众多隐蔽性油气藏的一种重要类型，具有很大勘探潜力。但砾岩体非均质性强，储集层较难评价，这是制约该类油气藏勘探的重要因素。通过对济阳坳陷罗家地区砾岩体储层特征及其控制因素分析，选择既能对储集层的储集性能好坏有鉴别能力，又能各自相对独立反映储集层某一特性的分类评价参数，以储集层微观孔隙结构为分类依据，以储集层物性为主要评价标准，以相对储集层厚度和单储集层平均厚度为评价参考，以沉积相、成岩相带为宏观指导，综合各种参数对砾岩进行了分类及评价。预测了有利储集层发育区，探讨了评价的可靠性、实用性。

Comprehensive evaluation on the classification of conglomerate reservoirs in Luojia area

Conglomerate oil-gas reservoirs, as one important type of the subtle reservoirs, have great potential in exploration. But the reservoirs are difficult to evaluate due to severe heterogeneity that is the important factor of re- stricting the exploration in this type of oil-gas reservoirs. All kinds of parameters are considered comprehensively to classify and evaluate the conglomerate. The parameters should have the identifying ability of the reservoir properties and of reflecting certain property of reservoirs independently for each of them through the analysis of reservoir feature and its controlling factors of the conglomerate body in Luojia area, Jiyang depression. The basis of classification is microscopic pore structure. The main evaluation standard is physical properties of reservoir bed, the referencing standards are the relative thickness of reservoir bed and average thickness of single reservoir bed, and the sedimentary facies and Iithogenous phase serve as macroscopic guidance. Favorable reservoir developing area is predicted, and the reliability and practicability on e-valuation are discussed.
