| Abstract: | l production technology of zone replacement is studied aiming at the problems of high combined water cut and serious interference between layers. Using this technology can finish water finding and water plugging together and meet the need of random replacement among one to four layers. Successful ratio and effectiveness ratio, oil well production rate, and the potential of non-major reservoirs are improved. The operating well times and operating cost are decreased, and pollution damage of oil reservoir is lightened. Obvious economic and social benefits are achieved in field application. |
