Abstract
The utility model discloses an open-free concentric adjustable water distributor which comprises an upper connector and a lower connector. An outer pipe and a fixed spout body are sequentially connected between the upper connector and the lower connector. A seal valve is disposed between the outer pipe and the fixed spout body. A rotary core is disposed in an inner cavity formed by the upper connector, the outer pipe, the seal valve, the fixed spout body and the lower connector. An annulus is formed between the fixed spout body and the outer pipe. A one-way moving positioning device is nested in the annulus. A spring is disposed on the one-way moving positioning device. The upper end of the spring is butted against the lower end face of the upper connector. A water filling tubular column is set by first compressing, normal water filling is achieved by second compressing, and one downhole operation of instruments can be omitted.
Description
Technical field
The utility model relates to Concentric adjustable water distributor, specifically exempts from the open type Concentric adjustable water distributor.
Background technology
Present existing Concentric adjustable water distributor realizes opening, closing or regulate the water nozzle size by the mutual rotation of two perforate spools up and down purpose realizes the quantitative water distribution to water filling layer position.When needing the allotment water injection rate, only need be lowered to special-purpose downhole measurement adjusting device, according to the test data of coming on the real-time Transmission, rotate fuse and fixedly water nozzle relative motion by the action of gauging means under the GCU control well, thereby realize the adjusting of injection well downhole flow regulator uninterrupted.This device is unidimensional with one heart, and layering progression is unrestricted, has satisfied the requirement of multistage water distribution; Also have simultaneously anti-returning and tell function, can prevent from effectively when stopping annotating that the stratum from returning to tell, prevent formation sand production.But for the well that uses compression packer, Concentric adjustable water distributor is to be in closed condition when going into the well, and must be lowered to instrument after tubing string sets and open normally water filling of Concentric adjustable water distributor.
Summary of the invention
The purpose of this utility model is to provide exempts from the open type Concentric adjustable water distributor, suppresses for the first time and sets water injection string, suppresses for the second time and can realize normal water filling, can remove well operations under instrument from.
In order to reach above-mentioned purpose, the utility model provides following technical scheme, exempts from the open type Concentric adjustable water distributor, comprises top connection and lower contact, be connected with outer tube and fixing water nozzle main body between described top connection and the lower contact in turn, described outer tube and fixedly be provided with the sealing valve between the water nozzle main body; Be provided with the rotation fuse in described top connection, outer tube, sealing valve, the tube cavity that fixedly water nozzle main body, lower contact consist of; Form annular space between described fixedly water nozzle main body and the outer tube, this annular space inner sleeve has the single-way moving positioner.
Described single-way moving positioner top is provided with spring, and this spring upper end withstands on the lower surface of top connection.
Described rotation fuse upper end is positioned at fixedly, and the water nozzle body position offers water nozzle.
Described top connection top is connected with the anti-fuse that revolves.
Compared to prior art, the beneficial effects of the utility model are: for the water injection well that uses compression packer, Concentric adjustable water distributor is to be in closed condition when going into the well, and must be lowered to instrument after tubing string sets and open normally water filling of Concentric adjustable water distributor.Exempt from the open type Concentric adjustable water distributor and use, to suppress for the first time and set water injection string, to suppress for the second time and can realize normal water filling, can remove well operations under instrument from.
Description of drawings
Fig. 1 is the structural representation that the utility model is exempted from the open type Concentric adjustable water distributor.
Among the figure: 1, the anti-fuse that revolves; 2, top connection; 3, spring; 4, single-way moving positioner; 5, sealing valve; 6, fixing water nozzle main body; 7, rotation fuse; 8, lower contact.
The specific embodiment
Relevant detailed description of the present utility model and technology contents cooperate description of drawings as follows, yet accompanying drawing only provides the usefulness of reference with explanation, and the utility model is limited.
According to shown in Figure 1, exempt from the open type Concentric adjustable water distributor, comprise top connection 2 and lower contact 8, be connected with outer tube and fixing water nozzle main body 6 between described top connection and the lower contact in turn, described outer tube and fixedly be provided with sealing valve 5 between the water nozzle main body; Be provided with rotation fuse 7 in described top connection, outer tube, sealing valve, the tube cavity that fixedly water nozzle main body, lower contact consist of; Form annular space between described fixedly water nozzle main body and the outer tube, this annular space inner sleeve has single-way moving positioner 4.Described single-way moving positioner top is provided with spring 3, and this spring upper end withstands on the lower surface of top connection.Described rotation fuse upper end is positioned at fixedly, and the water nozzle body position offers water nozzle.Described top connection top is connected with the anti-fuse 1 that revolves.
When water injection string was suppressed set packer for the first time, single-way moving locking device 4 was up until positioning step is no longer up, and seal valve and also water nozzle is in sealing state this moment, continued to suppress to set.Pressure release after packer setting is complete, the sealing valve playbacks under the effect of spring force, and locating piece is descending to come off simultaneously, and the sealing valve does not have the upward position restriction when again suppressing, and exposes water nozzle and begins water filling.
During allotment, the steel wire cable operation is lowered to special-purpose downhole measurement adjusting device, after it locates, start gauging means, 7 rotations of driven rotary fuse are adjusted and the fixing relative position of water nozzle main body 6, thereby regulate the aperture size of water nozzle, reach the purpose of stepless quantitative allotment water injection rate.
The above only is preferred embodiment of the present utility model, and non-in order to limit claim of the present utility model, other use the equivalence of patent spirit of the present utility model to change, and all should all belong to claim of the present utility model.
