油气盖层力学性与封闭性关系

Relationship between Dynamics of Caprocks and Characteristics of Seal

本文以滇黔桂地区７种不同岩性的盖层岩样，进行了岩石力学性质测试计算，对油气盖层的力学性与封闭性关系进行了研究。用岩石抗压强度、硬度，塑性系数等主要力学参数，对盖层岩石进行了分类。对影响岩石力学性质的主要因素进行了分析，提出了盖岩力学性的初步分类标准，从力学性角度对膏岩、泥灰岩、碳酸盐岩等的封闭性进行了评价，为油气保存条件的研究提供了一些定量数据．

According to the rock dynamic analyses of seven different kinds of caprocks in Dianqiangui area, the authors focus of the relationship between dynamics of eaprocks and characteristics of seal,and classify the caprocks. In this paper, the authors also analyze the main factorswhich influence the caprock dynamics,and quantitatively evaluate the seal characteristics ofcarbonate, mud and gypsolith.
