摘　　要：现在RPM(储层性能监测仪)被广泛应用于剩余油饱和度监测中,并且RPM中的碳氧比测井模式基本不受地层水矿化度的影响,能够较好的获取低矿化度地层的剩余油饱和度。本文利用蒙特卡洛模拟程序MCNP分别模拟了套管尺寸对碳氧比测量结果的影响,此外针对海上油田复杂管柱结构探索性对砾石充填影响进行了模拟。通过模拟结果进行数据处理并绘制交会图版,进行敏感性分析,并根据需要拟合出各影响因素与碳氧比值的关系函数。Nowadays, Reservoir Performance Monitor is applied to monitoring the remaining oil saturation, and carbon oxygen log mode of Reservoir Performance Monitor is almost unaffected by formation water salinity, which can better acquire the formation of remaining oil saturation. The paper employ Monte Carlo simulation program MCNP to imitate C/O respectively with the changes of casing thickness, casing diameter. Additionally, it simulates the influence of gravel packing on the complex structure of the offshore oil field. According to process the simulation results and draw the cross plot, it is possible to perform the sensitivity analysis and fit the relationship between the various influencing factors and the carbon oxygen ratio.
