摘　　要：鄂尔多斯盆地镇泾油田长8油藏属于致密超低渗油藏,影响其产能的因素很多,关系也很复杂,给产能预测带来了诸多困难。通过找寻油层、差油层、油水同层及干层在测井曲线上的响应特征,来加以区分识别。对识别出的油层、差油层及油水同层,分别计算其有效厚度,并通过试油资料找出对产能影响较大的因素。利用这些数据构建出一个与产能有良好线性关系的相关系数,并根据该相关系数与产能的线性关系对产能进行预测。The Chang 8 reservoir in Zhenjing Oilfield in Ordos Basin is ultra-low permeability reservoir. There are various factors influencing the production with complex correlation, which brings a lot of difficulties in productivity prediction. The log response characteristics of oil layer, poor-oil layer, oil-water layer and dry layer are identified and the effective thickness of oil layer, poor-oil layer and oil-water layer are calculated. The main factors influencing the productivity are found out by testing data, by using which a correlation coefficient has good linear relation with productivity is build up, and then the productivity is predicted.
