摘　　要：根据双TE测井可以获得地层固有弛豫时间T2int和地层烃与水的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差异分配可动流体进而得到可动烃与可动水体积,利用截止值法确定毛管束缚水体积。可动烃体积、可动水体积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。该方法被编制到了核磁共振测井油气识别与评价模块FLAN中,应用该模块处理并解释了多个地区多口井的实际资料,获得了较好的油气识别与评价效果。According to dual-TE logging,intrinsic relaxation time T2int and the T2int deviation between hydrocarbon and water can be obtained,which can be used to discriminate the formation fluid property and evaluate the hydrocarbon saturation.It is using T2int deviation to obtain volumes of the movable hydrocarbon and movable water,and using cutoff value to determine the volume of capillary bound water.The hydrocarbon saturation could be obtained after these volumes were calibrated by hydrocarbon index.This method has been compiled to FLAN module for oil and gas identification and evaluation by nuclear magnetic resonance log.The real data of many wells are processed by this module.The result proves a good effect.
