Abstract
The utility model provides an eccentric water distributor, comprising a work cylinder main body, two sides of an eccentric hole are both provided with a flow guide groove forming a certain included angle with an axis, making sediments sinking into a tail pipe along the flow guide grooves, preventing sediments from accumulating at a salvaging head part of a blanking plug, keeping the salvaging head part of the blanking plug clean, and reaching purpose of smooth salvaging.
Description
Technical field
The utility model relates to a kind of injection well downhole flow regulator, especially relates to a kind of eccentric injection mandrel that prevents foul in inside deposition.
Background technology
At present, eccentric injection mandrel commonly used both at home and abroad is to carry out one of downhole tool of layered quantitative water filling according to the different water absorbing capacities of oil reservoir.During normal water filling, packer is divided into some water filling intervals to oil reservoir.The blanking plug of correspondence in each water filling interval leans on the step (diameter phi 22mm) of supporter to be seated in the inclined to one side hole of seating nipple main body, and cam is stuck in the upper step of inclined to one side hole, and blanking plug two group of four road packing is up and down sealed inclined to one side hole fluid hole.Inject water through filter screen,, inject target zone by water nozzle, seal section liquid outlet groove, after the hole fluid hole enters the oil jacket annular space partially.The seperated layer water injection amount, can be changed when finding that the water nozzle diameter is improper at any time by the control of water nozzle diameter.But in the process of water filling, because of oil pipe fouling, corrosion or inject the water generates deposit buildup on seating nipple main body step, the blanking plug fishing head is buried, cause test crash, have only operation cleaning tubing string on the enormous expenditure of input, increased the expenditure of water filling cost.
Summary of the invention
The purpose of this utility model just is to solve in the separated-zone water infection oil field tubing string technology, because of tubing string encrustation, corrosion thing come off, and deposits on eccentric injection mandrel seating nipple main body step, very easily causes the problem of test pulling failure.
The purpose of this utility model can realize by following measure:
The utility model comprises the seating nipple main body, is equipped with the guiding gutter in a certain angle with axis in the both sides in the inclined to one side hole of seating nipple main body, makes deposit sink to tail pipe along guiding gutter, prevents that deposit from piling up at blanking plug fishing head position.
The beneficial effects of the utility model are that deposit can sink to tail pipe by guiding gutter, prevents that deposit from the accumulation of blanking plug fishing head position, improving the test success rate.
