Simulation of improving development effectiveness of Daqing oil field Chao 45 tract

The oil reservoir physical properity of Daqing oil field Chao 45 tract is very poor, with low permeability, so the oil reservoir pressure keeps dropping, with quick reduction of output, and water cut goes up quickly. To find the waterflooding technique for low\|permeability oil field, improve the development effectiveness of Chao 45 tract, we simulate the tract's development history in VIP model. Based on the history matching, we stimulate the development effectiveness of various well stimulation, predict 7 kinds of development programs. The result of prediction is that the injection pressure should not be too high because of the subtle fractures; the best development project is in proper order infill well net\|work, linear injection, water plugging, shutting down high water cut well, water injection profile control; the best injection\|to\|production ratio is 2.
