鄂北塔巴庙地区上古生界低孔渗储层地震预测技术及应用

SEISMIC PREDICTION TECHNIQUE FOR UPPER PALEOZOIC LOW-POROSITY AND LOW-PERMEABILITY RESERVOIRS IN TABAMIAO AREA OF NORTH E'ERDUOSI BASIN

鄂尔多斯盆地北部塔巴庙地区上古生界储层具有薄互层、低孔渗、高阻抗、普遍含气等特征。利用高分辨率地震资料 ,有针对性的采用了一系列地震处理解释方法技术 ,以BCI和ANN技术为主体 ,辅助以其它方法作为综合分析和验证。将地震、地质、测井、测试紧密结合 ,有效地预测了山西组和下石盒子组 10m以上的储层及其含气性 ,预测砂体符合率和钻井成功率在 75 %以上。同时根据预测情况对工区进行了综合评价 ,指出了工区储层有利分布区 。

The upper paleozoic reservoirs in Tabamiao area of North E'erduosi Basin are of such characters as thin interbeds,low porosity,low permeability,high impedance and gas-bearing universality.The reservoirs with a thickness of more than 10 m in the P 1s and P 1x formations and their gas-bearing state have been effectively predicted by using the high-resolution seismic data,through adopting a series of seismic processing and interpretation methods and technique with a clear aim,through a comprehensive anal...
