Abstract

The invention discloses a zonal injection allocator with inner magnetic flow meters and wireless charge and transmission functions and a use method of the injection allocator, belongs to the field of underground oil injection equipment, and solves the problems of low measurement control precision of injection quantity and difficult information acquisition and charge in a conventional oil field polymer injection well. The zonal injection allocator comprises a zonal injection allocator main body, and further comprises an inner magnetic flow meter I, an inner magnetic flow meter II, a wireless charge module and a wireless transmission module, wherein the inner magnetic flow meter I, the wireless charge module and the wireless transmission module are all fixed to the outer side of an upper joint body in a sleeving manner and are coaxial with the upper joint body; the inner magnetic flow meter II is fixed to the outer side of a central pipe in a sleeving manner, is coaxial with the central pipe and is in close contact with the upper layer and the lower layer of a housing body; the wireless charge module is used for wirelessly charging an underground battery, and the wireless transmission module is used for wirelessly transmitting flow data of the injection allocator. The zonal injection allocator is mainly used for performing flow injection on an underground oil field.

Description

technical field [0001] The invention belongs to the field of downhole oil injection equipment. Background technique [0002] In order to further enhance oil recovery, polymer oil recovery has become an important means and method of oil field development after water flooding. However, due to the high viscosity of the polymer and the complex downhole environment, the current manual fishing technology can no longer achieve flow monitoring and accurate flow injection. At the same time, the manual fishing technology is difficult to construct and cannot meet the requirements of polymer injection. Therefore, it was decided to carry out injection Well-gathering wireless technology is used to realize real-time monitoring of injection volume and improve oil displacement effect. Existing traditional equipment, such as the device described in the patent document CN 103352678 A "Polymer Injection Water Injection Selective Layered Continuous Adjustable Injection Device" published on Octo...
