多轮次调剖数值模拟研究

NUMERICAL SIMULATION RESEARCH ON TIMES PROFILE CONTROL

多轮次调剖是一项重要的稳油控水措施 ,提出了三维三相多轮次调剖数学模型 ,研制了多轮次调剖模拟器。综合考虑了模拟器中堵剂驱油过程中的物理特性 ,为高含水期油藏进行多轮次调剖油藏工程方案研究提供了有力的工具。结合具体油藏模型 ,进行了调剖时机、堵剂用量及封堵位置对调剖效果的影响研究。结果表明 ,在油田进入高含水期 ,要不断地进行调剖 ,及时进行各轮次调剖堵水措施间的接替 ,使油田含水得到控制 ,产量稳定增长。

Times profile control is one of the important methods to water control and oil stable production. 3D three phase times profile control mathematical model was designed and the simulator was developed, in which physical characteristics of the plugging agent during displacing were synthetically considered. This simulator was an excellent tool for times profile control project research on high water cut stage reservoir. Combining idiographic reservoir model, the influence of profile control occasion, quantity of plugging agent, plugging position to profile control effect was studied. It was testified that during the high water cut stage, to control water cut and stably increase the oil production, profile control should be carried through constantly, and times profile control should be relayed on time.
