Abstract
The utility model relates to an anti-sand-burying eccentric water distributor which is composed of the components of: an upper joint (1), an upper connecting sleeve (2), a centralizer (3), a body (4), a lower connecting sleeve (5), a guiding member (7) and a lower joint (8). The position on the upper joint (1), which is jointed with the centralizer (3), is provided with a plurality of shunting grooves (11). A flow guiding groove (3) is spirally arranged on the outer wall of the centralizer (3) from top to bottom. A flow guiding ring (32) is arranged between the outer wall of the centralizer (3) below the flow guiding groove (31) on the outer wall of the centralizer (3). When the anti-sand-burying eccentric water distributor is used for flushing the position of a salvage rod of an obstruction device, more centralized water current is realized, and sand burying onto the position of the salvage rod of the obstruction device can be effectively prevented. The technical effect of the anti-sand-burying eccentric water distributor is characterized in that: when the anti-sand-burying eccentric water distributor is used for flushing the position of the salvage rod of the obstruction device, more centralized water current is realized, and sand burying onto the position of the salvage rod of the obstruction device can be effectively prevented.
Description
Technical field
The utility model relates to oil field water well water injection tool, is specifically related to a kind of water filling injection well downhole flow regulator can sand control burying.
Background technology
Oil field water well when operation, often occur that blanking plug fishing rod position is buried by the grains of sand in water, dirt and the phenomenon that can not carry out normal pulling.The sand control of existing three road helicla flute shuntings buries structure, because its current are concentrated not, can not effectively prevent that sand from burying the generation of phenomenon.
Summary of the invention
The purpose of this utility model be to provide a kind of current more concentrated, can effectively prevent that the sand control that sand buries blanking plug fishing rod position from burying eccentric injection mandrel.
Technical solution of the present utility model is: it is by top connection, upper joint sleeve, centralizer body, main body, lower joint sleeve, support, guide way and lower contact form, the upper end of top connection is provided with the internal thread being connected with tubing string, the lower end of top connection is connected with the upper end of upper joint sleeve by screw thread, the lower end of upper joint sleeve is connected with the upper end of main body by screw thread, centralizer body is arranged between top connection and main body in upper joint sleeve, the lower end of main body is connected with the upper end of lower contact by screw thread, support is arranged between main body and lower contact in lower joint sleeve and lower contact, guide way is arranged in support, the lower end of lower contact is provided with the external screw thread being connected with tubing string, the position clamping mutually with centralizer body on top connection end opening is provided with several splitter boxs, on centralizer body outer wall, be provided with twist from the top down a guiding gutter to blanking plug fishing rod position water conservancy diversion, on centralizer body outer wall, between the below centralizer body outer wall of guiding gutter and upper joint sleeve inwall, be provided with one with guiding gutter the guide ring of the identical hand of spiral.
Technique effect of the present utility model is: use its current in the time rinsing blanking plug fishing rod position more concentrated, can effectively prevent that sand from burying blanking plug fishing rod position.It is except adopting forward-reverse spiral guiding gutter to carry out water conservancy diversion, also under guiding gutter along the guide ring that has installed effective shutoff current water conservancy diversion additional, also have multiple splitter boxs in injection well downhole flow regulator top connection place.Under the comprehensive function of splitter box, guiding gutter and guide ring, current are concentrated and are flow through blanking plug fishing rod place, thoroughly solved after injection well downhole flow regulator blanking plug sand buries can not pulling problem.
