低密度井眼流体会对补偿中子孔隙度测井产生井眼挖掘效应,使视孔隙度值低于真孔隙度,且井眼流体密度越小,井眼尺寸越大,地层孔隙度越大,井眼挖掘效应越明显。
The low density drilling fluid has borehole excavation effect on compensated neutron porosity logging, and by this way apparent porosity is lower than the true value.
流体含水测井曲线出现异常,曲线幅度变化与流体密度曲线正好相反;
Fluid identification logging curve is abnormal, the curve amplitude change is inversed with the fluid density curve;
