Description
Technical field
The utility model belongs to oil-field flooding field, and in particular to a kind of wellhead of water injection well.
Background technology
Currently used wellhead of water injection well is by eight valves, as Water filling valve 1, sleeve pipe imported valve 2, oil pipe enter in Fig. 1
Mouth valve 6, oil pipe outlet valve 7, test valve 8, total valve 9, emptying valve 12, cannula exit valve 13, lower four entire bodies 15,
Upper four entire body 14, tubing gauge 5, casing pressure table 10, ball-and-seat 3, sample tap 4 form.Action includes：It is positive injection, anti-
Note, just wash, backwash, surveying water suction curves, sampling, emptying etc..There is deficiency existing for device：Valve is more, and it is big to change flow workload, behaviour
Make complicated；Component parts is more, and cost is high, and later maintenance workload is big.
Utility model content
Technical problem to be solved in the utility model is to be directed to above-mentioned deficiency of the prior art, there is provided a kind of water filling
Well well head, running cost is reduced, improve the activity duration.
The utility model uses following technical scheme：
A kind of wellhead of water injection well, including be separately positioned on the sleeve pipe imported valve on the left of wellhead of water injection well and be arranged on right side
Cannula exit valve, described sleeve pipe imported valve is connected through piping with ball-and-seat, and the ball-and-seat passes through four-in-one valve
It is connected with described sleeve pipe outlet valve, the four-in-one valve is connected through piping with the wellhead of water injection well.
Further, described sleeve pipe outlet valve is also associated with being vented valve.
Further, described sleeve pipe imported valve on the pipeline of the ball-and-seat with being provided with sample tap.
Further, it is provided with tubing gauge between the ball-and-seat and the four-in-one valve.
Further, it is provided with casing pressure table between the four-in-one valve and described sleeve pipe outlet valve.
Further, the four-in-one valve is provided with four passages, for realizing four kinds of flows.
Compared with prior art, the utility model at least has the advantages that：
The utility model wellhead of water injection well includes being separately positioned on sleeve pipe imported valve and the setting on the left of wellhead of water injection well
Cannula exit valve on right side, described sleeve pipe imported valve are connected through piping with ball-and-seat, and the ball-and-seat closes by four
One valve is connected with described sleeve pipe outlet valve, and the four-in-one valve is connected through piping with the wellhead of water injection well, is passed through
One four-in-one valve substitution oil pipe inlet valve, oil pipe outlet valve, test valve and main valve, and pass through a Valve controlling control note
Water flow-path, operation is convenient and swift, improves whole system operating efficiency.
Further, using four-in-one valve, the cost of four valves of simple wellhead is reduced, by changing valve angle
Replacing needs flow, reduces change flow and switchs multiple valve times, improves operating efficiency, reduce staff labor intensity.
Below by drawings and examples, the technical solution of the utility model is described in further detail.
