Abstract
The utility model discloses a small-diameter eccentric water distributor, relating to a water distributor, which aims to resolve the problem that the steel body of the existing eccentric water distributor has the smallest outer diameter of 95mm and the existing eccentric water distributor can not realize separate layer water injection on a casing damaged water injection well with the smallest diameter of 105mm. An upper outer cylinder of the water distributor is internally equipped with a centralizer, the lower outer cylinder is internally equipped with a guide body, the central lines of the centralizer, a working barrel body and the guide body are of a first axis, the central lines of an upper connector and a lower connector are of a second axis, the upper connector and the upper outer cylinder are in threaded connection as well as between the upper cylinder and the working barrel body, between the working barrel body and the lower outer cylinder and between the lower outer cylinder and the lower connector, the outer diameters of the upper connector, the upper outer cylinder, the working barrel body, the lower outer cylinder and the lower connector are Phi 90mm, and the inner diameters of the centralizer, the working barrel body and the guide body are Phi 46mm. The small-diameter eccentric water distributor enables the 5(1/2) inch casing damaged water injection well with the smallest diameter of Phi 100mm to realize separate layer water injection, thereby increasing the separate injection rate of oilfield water injection wells.
