|
摘要
针对胶结模型的特点,考虑实际油藏高温高压条件,建立了一套胶结三维油藏物理模拟饱和度测量系统。采用电阻测量原理,确定了饱和度测量方法;考察了多种材料和样品,最终选定了一种微型探针。重点解决了以下难题并形成技术:(1)高温高压胶结三维物理模拟饱和度测量技术;(2)饱和度探针密封技术;(3)内模型饱和度导线群集中外引密封技术。最后利用这套饱和度测量系统进行了聚合物驱三维物理模拟实验,通过聚合物驱开采曲线和饱和度场图,研究了聚合物驱提高原油采收率的宏观渗流机理。
Aiming at the characteristics of consolidated model,a set of saturation measurement system for consolidated 3-D reservoir physical simulation is set up by considering the practical conditions of high temperature and high pressure.The principle of resistance measurement is adopted to determine saturation,a micro-probe is selected finally by evaluating multiple materials and samples.The following key problems are solved and the related technologies formed,saturation measurement technology for consolidated 3-D physical simulation and high temperature and high pressure,the technology for external sealing of internal model saturation traverse lines.At last,the measurement system is employed to carry out 3-D physical simulation of polymer flooding.The macro mechanism of flowing through porous media of enhancing oil recovery by polymer flooding is studied with recovery curve of polymer flooding and the plot of saturation field.
