基于模糊数学的豫东煤系气资源勘探有利区预测
|
摘要
为了预测煤系气勘探开发的有利区,研究基于模糊数学的理论,系统分析了影响煤系气的生成条件、储层条件、含气条件及地质条件等因素,建立了豫东地区煤系气有利区预测的评价体系,结合模糊数学的计算方法,最终得到了相应的综合评价系数。研究结果表明:初步预测豫东地区煤系气最有利区块位于ⅱ1和ⅳ1区块,综合评价系数为0.808和0.788。两区块良好的含气性和储层条件,表现出更有利于煤系气的勘探开发。
In order to predict the favorable zone for exploration and exploitation of coal measure gas,based on the theory of the fuzzy mathematics,the study had a systematic analysis on the formation condition,reservoir condition,gas bearing condition and geological condition as well as other factors affected to the coal measure gas and a prediction evaluation system of the coal measure gas favorable zone in Eastern Henan Area was established. In combination with the calculation method of the fuzzy mathematics,the relevant comprehensive evaluation coefficients were finally obtained. The results showed that the most favorable blocks of the coal measure gas on Eastern Henan Area as the preliminarily predicted would be Block ⅱ1 and ⅳ1,and the comprehensive evaluation coefficients were 0.808 and 0.788 individually.The good gas bearing and reservoir conditions of the two blocks would be more favorable to the exploration and exploitation of the coal measure gas.
