摘　　要：深入分析了大牛地气田上古生界致密储层的地质取心、常规测井、试井成果等资料,特别是对"下石盒子组—太原组"各层段主要含气层(盒3、盒2、盒1、山2、山1、太2段)的测井曲线变化规律进行了系统剖析,在对储层参数精细解释的基础上,对气层产能进行了定性和定量评价方法的反复试验研究和精细处理分析,研究了气层无阻流量预测方法——测井储能特征系数法和测井参数优化合成法。前者从测井比值法出发,用测井特征储能系数法建立大牛地气田主要含气层系测井产能预测的综合计算方法;后者用优化组合法建立了利用测井参数合成关系预测储层天然气无阻流量的评价方法。该方法在大牛地气田上古生界致密储层天然气无阻流量的预测中取得了好效果。This paper thoroughly analyzes the geological core data, ordinary logging data and well test outcome of Neopaleozoic tight reservoir in Daniudi gas field, especially makes systematic dissection on the log curve change law of main gas-bearing reservoirs from Lower Shihezi formation to Taiyuan formation such as He-3, He-2, He-1,Shan-1, and Tai-2. Based on the fine interpretation of reservoir parameters, through the repeated experimental study on on qualitative and quantitative evaluation method and fine processing analysis, this study provides the log productivity characteristic factor method and the log parameter optimize method. The former is based on log ratio method and builds up the synthetical computing method of the main gas reservoir series in Daniudi gas field with log characteristic productivity factor. The latter is based on the optimized method, which builds up the evaluation method of predicting reservoir gas AOF with log parameter composite relation. The successful application in the Daniudi gas field shows that the two methods are of originality with remarkable effect.
