摘　　要：为解决塔里木盆地克拉2气田储层定性评价过程中评价指标互相矛盾的问题,应用灰色关联度分析法确定了储层评价指标的权系数,计算出储层综合评价指标,重新对气藏圈闭内巴什基奇克组储层进行综合定量评价,并给出了储层分类结果,应用产能数据对储层评价结果进行了验证。结果表明,巴什基奇克组一段储层定量分类符合率为87%,巴什基奇克组二段储层定量分类符合率为85%,分类结果具有一定的可靠性,可为气田开发决策提供依据。In order to solve the problem of contradictory evaluation indexes in the process of qualitative evaluation of Kela 2 gas field in Tarim basin,the weight coefficient of evaluation indexes was determined by grey relational analysis,the comprehensive evaluation index of the reservoir was calculated.The comprehensive quantitative evaluation of the reservoirs in the Baskichik formation in the trap was carried out,the results of reservoir classification were given,and the reservoir evaluation results were verified by using the productivity data.The results show that the coincidence rate of the quantitative classification of the first reservoir of Baskichik formation is 87%,and the coincidence rate of the second reservoir of baskichik formation is 85%.The classification results are reliable and can provide the basis for decisionmaking of gas field development.
