井眼补偿和井眼校正不同。
Borehole compensation is different from borehole correction.
井眼补偿技术用于与波的传播有关的测量，如声波、传播电阻率和电磁波传播测量。
The technique is used for measurements that rely on the propagation of a wave, such as sonic, propagation resistivity and electromagnetic propagation measurements.
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.
