NUMERICAL SIMULATION RESEARCH ON TIMES PROFILE CONTROL

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.
