However, it is found that porosity difference between NMR and conventional porosity logging is unacceptable in some oilfields in China.
但是，在我国部分油田的应用中发现核磁测井孔隙度与常规孔隙度之间存在明显差异。
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.
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。
Rational interpretation of well track position in reservoir, changes of resistivity logging response and of porosity logging response are made by using XXX horizontal well as examples.
以XXX水平井为例，对井眼轨迹在储层中的位置，以及电阻率测井响应和孔隙度测井响应的变化做出了合理的解释。
