For the construction of 85 secondary working standards for neutron logging for COSL, determined the content of rock analysis of the well. Simulated the response of a compensated neutron porosity logging tool in borehole diameter 200 mm pure limestone well by Monte Carlo simulation method, and determined the instruments standard response relationship. Mixed with different amounts of impurities in the limestone, simulation and calculation of the allowable range of the impurity elements.%针对中海油服建造85口中子孔隙度井的需要,提出了刻度井的岩石分析内容.通过蒙特卡罗模拟了一种补偿中子孔隙度测井仪在井径为200 mm的纯灰岩刻度井中的响应,得到了仪器的标准响应关系.在灰岩中掺入不同含量的杂质,模拟并计算了杂质元素含量的允许范围.
