鄂尔多斯盆地北部塔巴庙地区气层识别与预测

塔巴庙地区位于鄂尔多斯盆地北部伊陕斜坡带，气层主要为上古生界山西组山1段和下石盒子组盒1段河道砂体。总结塔巴庙地区气层的岩石学、电性、地球物理特征，建立了识别气层、水层、干层的测井参数解释标准，并根据地震特殊处理，对塔巴庙地区的山1、山2、盒1、盒2等主要产层段的储集层进行了含气性预测，认为塔巴庙地区砂体主体分布区基本较为有利，尤其是DT1井—昌鸡兔—带砂体发育，含气饱和度高，为最有利区。同时，这种分布特征也证实了盆地北部上古生界深盆气藏的成藏特征。

Gas reservoir recognize and prediction of Tabamiao Region in north Ordos Basin

Tabamiao is located at Yishan Slope Stripe in north Ordos Basin. The gas reservoir rocks is mostly consisted of Late Palaeozoic P 1 x and P 1 s riverway sandstone. The study summarize the lithology, electricity and geophysical character of Tabamiao gas reservoir, which set up the criterion of log parameters to recognize the gas, water and dry layers. Then it predicted the gas distribution of domain produce layers by using seismic special disposal technique. The result indicates that in most Tabamiao Region where has abundance sandstone is relatively favorable, especialy in area around Well DT 1 and Changjitu where sandstone grow and has a high gas saturation. The gas distribution feature prove that north Ordos Basin gas reservoir belongs to a deep basin gas.
