摘要
从油气藏形成的基本条件及动态过程出发，利用模糊数学方法，建立了一套圈闭含油气性综合评价方法。并将其应用于汤原断陷主要目的层——Ｅ４２段的５８个圈闭的含油气性的综合评价中，得到含油气性好的圈闭７个，较好圈闭６个，中等圈闭１２个，差圈闭３３个，并且得知，由南向北圈闭的含油气性由好变差。较客观地反映了该断陷Ｅ４２段中的油气分布状况。
Based on the basic conditions forming oil and gas pools and their dynamic process, we established the comprehensive evaluation method for the oil and gas prospect of traps by the method of fuzzy mathematics, and used it in evaluating comprehensively the oil and gas prospect of traps in E 4 2 member of Tangyuan depression, finding 7 traps to be best, 6 traps to be better, 12 traps to be medium, 33 traps to be poor. The oil and gas prospect of traps was good in the north part of the depression while that was bad in the south part of the depression. The results objectively reflect the oil and gas distribution and provide the basic data for the oil and gas prospecting in Tangyuan depression.
