| It is the important method to controlling water and steadying oil in the late-mid period of oil development. During the high-water-cut of oil field, The injection-production relationship becomes increasingly complex, The anisotropism become more serious every day, The remaining oil is getting more complex. All of these bring about the more and more difficulties in stabilizing oilfield productivity and topping potential. Especially during the high-water-cut, controlling water and steadying oil is the fundamental policy.Through more than thirty years'development in Block Mu152, it has gone into the stage of"three high". The"three contradiction"is prominent. The condition of oil well is becoming worse and worse. Remaining oil becomes disperse state. It is serious for the circle of non-available water. It is higher for the water content of oil well and it is more difficult of the steadying oil. So this demand we must put the targeted steady strategy into effect to improve development results.Base on the analysis to the reservoir, the injection-production relationship is made sure further. The oil development conflicts have been researched at the present time, and the regularity of distribution of the remaining oil is studied, therefore it is determine that adjusting displacement is the main direction of attack to improve the development results through the application of the static data, dynamic data and reservoir monitoring data and the application of the dynamic analysis, the sedimentary microfacies, reservoir monitoring technology and so on.Through the research to the Block Mu152 reservoir, we optimized the experimental injection well group, operation parameter. The pilot test has been carried out in 2009. It is obvious of the test effects. It has provided the strong guide for the next development policy and the method of the enhance oil recovery. |
