Abstract
Disclosed is a system for segmented simultaneous water injection and oil recovery through double pipes in horizontal section, comprising several packers, several oil-extracting mechanisms and several water-injection mechanisms, wherein each of the packers, each of the oil-extracting mechanisms, and each of the water-injection mechanisms has an injection channel and a production channel, when several packers, several oil-extracting mechanisms and several water-injection mechanisms are combined, each of the injection channels is connected in turn, and each of the production channels is also connected in turn, the oil-extracting mechanism can extract oil through the production channel, the water-injection mechanism can inject water through the injection channel. The beneficial effects of this disclosure include: the oil in the oil production section can be produced while the water injection section is injected with water. The cost of water injection is effectively reduced, the efficiency of water injection is improved.
