摘　　要：综合利用岩芯物性资料、压汞资料及试气资料,采用经验统计法、中值压力法、0.1μm进汞饱和度法、最小孔喉半径法和孔隙度-渗透率交会法确定下限值,并用试气法进行验证,得出松辽盆地南部W研究区中基性火山岩的孔隙度和渗透率下限值分别为3.558%和0.008 5×10^(-3)μm^2。With the integration of core physical property, mercury injection data and gas test data, the authors determined the lower limit value by empirical statistics, median pressure method, 0. 1 μm mercury saturation meth- od, pore throat radius method, porosity-permeability cross-po method, and used the method of gas testing for vali- dation. It is concluded that porosity and permeability lower limit value were 3. 558% and 0. 008 5 x 10 -3 μm2 for the intermediate-basic volcanic rocks of W studied area in southern Songliao Basin.
