摘要
本文以迪基和真柄钦次提出的油气初次运移模式为根据,以江汉盆地的泥岩压实为基础,利用油水相对渗透率、油水饱和度和达西定律的关系,提出了计算排烃量的公式:Q=w·q·d.在选取参数时,直接用本区泥岩压实曲线计算了孔隙流体损失量,并借用研究区砂岩油水饱和度与油水相对渗透率关系曲线,求出相邻泥岩的不同油水饱和度下油水各自的相对渗透率比值.
In the light of the model of oil-gas primary migration proposed by Di-ckie and Zhen Bing Qinru, on the basis of the study on claystone compa-ction in Jianghan Basin, the authors have suggested a formula for the cal-culation of hydrocarbon expulsion quantity. Q = =w. q. d, using relative permeability of oil - gas, and the relation of oil-gas saturation to Darcy law. In selecting parameters, compaction curve of claystone in the region was ado-pted directly to calculate the quantity of interstitial fluid loss, meanwhile, with rating curve for oil - gas saturation versus relative permeability of oil - gas in the studied area, the ratios of relative permeabilities of oil - gas for the claystone under different saturations were calculated.
