硼中子寿命测井是向地层中注入高俘获截面的硼酸，从而使中子寿命测井也适用于低矿化度地区。对于低孔低渗储层，由于束缚水和残余油的含量很高，可动流体所占比例已很少，允许的误差范围也小，在定量求取剩余油饱和度时，具有不同于高孔高渗储层的新特点。文中结合二连油田地质特征，推导分析了低渗透砂岩储层的剩余油饱和度方程。最后用这一方程处理了二连油田一口水淹井的硼中子寿命测井数据，并作了详细分析，取得了很好的地质效果
Boron neutron lifetime logging is the injection of high capture cross-section boric acid into the formation, making neutron lifetime logs suitable for low salinity regions as well. For low-porosity and low-permeability reservoirs, due to the high content of irreducible water and residual oil, the proportion of movable fluid is small and the permissible error range is small. When the remaining oil saturation is quantitatively determined, New Features of High Porosity Reservoir. Based on the geological characteristics of Erlian Oilfield, the remaining oil saturation equation of low permeability sandstone reservoir is deduced and analyzed. Finally, this equation was used to process the boron neutron lifetime logging data of a water flooded well in Erlian Oilfield. The logging data were analyzed in detail and good geological results were obtained
