The invention discloses a stable downhole injector provided with a limit mechanism. Through the cooperative use of a series of components such as a push block, an impeller and a hose, the invention can push the hose to make the hose swing, Further, the liquid inside the hose is evenly distributed in the crude oil, and the agitation of the hose makes it evenly distributed; through the cooperative use of a series of components such as the horizontal plate, the mounting plate and the insert block, the present invention can support At the same time of operation, the entire dispenser is fixed, thereby effectively improving the stability of the present invention; through the cooperative use of a series of components such as limit blocks, limit grooves and threaded rods, the present invention can be configured according to While changing the liquid components, the corresponding conduits are replaced, so that the present invention can work better.
Description
technical field [0001] The invention relates to the technical field of downhole distributors, in particular to a stable downhole distributor provided with a limit mechanism. Background technique [0002] When the oil field enters the stage of secondary oil recovery, it is necessary to use water injection to enhance oil recovery. Due to the heterogeneity of each layer in the oil layer and the difference in pressure and permeability between layers, only the layered water injection method can be effective. To improve water injection efficiency and oil field recovery, downhole injectors have emerged as the times require. Downhole injectors are key tools for layered water injection. Existing downhole injectors are often used to directly inject The liquid is introduced into the crude oil downhole, which undoubtedly leads to uneven distribution of the injection fluid. At the same time, in the installation of the feed conduit, it is often impossible to replace the corresponding feed...
