摘要
随着海上S油田剩余油的深入开发,RPM测井正广泛应用于油藏动态监测之中。而国内RPM碳氧比饱和度测井的解释方法依赖于大量典型地层和井眼条件组合的庞大数据库,如何简单、直接地对RPM碳氧比测井资料进行解释成为了急需解决的问题。因此考虑井眼尺寸、井眼流体、套管尺寸、水泥环厚度、孔隙度、地层流体等影响因素建立地层真实模型,采用MCNP蒙特卡罗软件进行模拟,结果与理论一致。然后利用建立的蒙特卡罗解释图版对现场两口实际生产井RPM测井资料进行处理,计算含水饱和度相对误差分别为2.37%、8.29%,井眼持水率相对误差分别为3.12%、8.16%,取得了较好的应用效果。
With the gradual depth exploit of residual oil in offshore oilfield, RPM logging is used widely in reservoirs dynamic monitoring. However, the interpretation of domestic RPM C/O depends on huge database combining with a large number of typical formations and borehole conditions. It＇s an urgent problem to find a direct and simple way to interpret the RPM C/O logging data. With the characteristic of large hole and seriously affected by fluid at heavy oil reservoir, the volume model is designed considering the following influencing factors like borehole size, shaft fluid, casing pipe size, cement thickness, porosity, formation fluid. Then, it is simulated with the software of Monte Carlo, and the result is consistent with the theoretical values. The established Monte Carlo chart is used to interpret the RPM logging data of two production wells. The relative error of water saturation is 2.37% and 8.29% and the relative error of water holdup is 3.12% and 8.16%. Therefore, good application effect was achieved.
