Abstract
In the conversion process of the polymer flooding from Type one to Type two oil layers, there is still a certain productivity in partial major oil layers and moreover the fractional oil productivity is lost just resulting from the method of simultaneous changing the candidate wells in major oil layers into the development wells of Type two oil layers in the blocks of developed Type two oil layers. Focused on the problems mentioned above, in the course of well patter connection between Type one and two oil layers in Block A, batch optimized and used method is a-dopted: Type two oil layers are additionally perforated in the injectors of delayed major oil layers; the method of separated injection for Type one and two oil reservoirs is used; on the basis of ensuring the perfect injection and production of Type two oil layers, prolongs the production time of high-productivity producers of major oil layers and furthermore taps the potentials of the remained oil in principal oil layers after polymer flooding.关键词
