根据双TE测井可以获得地层固有驰豫时间T2int,利用地层烃与水的T2int差异,可用来定性判别地层的流体性质,也可用来定量评价含烃饱和度,即利用烃与水的T2int差异分配可动流体得到可动烃与可动水体积,利用截止值法可确定毛管束缚水体积。则可动烃、可动水与毛管束缚水体积经含氢指数校正,就可以得到地层的含烃饱和度。利用该方法处理与解释多口井的实际资料,取得了较好的效果。
Based on the double-TE logging, T2int can be obtained, and T2int difference between formation hydrocarbon and water can be used to qualitatively determine the fluid properties of the formation. It can also be used to quantitatively evaluate the hydrocarbon saturation, ie, T2int difference between hydrocarbon and water Dispensing the movable fluid to obtain the volume of the movable hydrocarbon and the movable water, the capillary bound water volume can be determined by the cut-off value method. Then the dynamic hydrocarbon, movable water and capillary bound water volume corrected by hydrogen index, we can get the formation of hydrocarbon saturation. The method of processing and interpretation of the actual number of wells, and achieved good results.
