摘要(Abstract)：
本文用岩样渗吸试验资料和离心机法测得的水-气毛管压力曲线资料,确定了大庆油田储气层的孔隙大小分布指数、原始含气饱和度和残余气饱和度,计算了水-气两相渗吸相对渗透率曲线,并对注水采气开发效果作了分析。
Based on the water-gas capillary prcssare curves measured on core samples through imbibition test and with centrifuge method, the pore size distribution exponent, initial gas saturation and residual gas saturation in gas-bearing reservoir in Daqing Oil Field are determined in the paper. Two-phase (water-gas) imbibition relative permeability curves are calculated and the results of gas development by waterflooding is analysed.
