Description
Technical field
This utility model relates to a kind of tool in oil well, a kind of Y-shaped connector for two-pump process tubing string.
Background technology
Offshore platform cost of winning is high, for reducing development cost, Bohai Bay Oil recent years more newly-built chain-wales or nothing
People's chain-wales, these platforms share a workover rig without workover rig or several platform.Therefore these Platform Requirements have
In the longer electric motor drive oil pump system cycle, reduce well repairing and pump checking operation.For solving this difficult problem, latent with entering two sets at present in oil well
Oil electric pump, forms individual well double electric pump combination oil extraction system, will be connected to same oil pipe by Y-shaped connector by two set pumping systems
On post, every electric pump is individually powered and controls by independent cable, by reasonably determining the working time of two set electric pumps
Make they alternate runs, improve total effective run time of the double pumping systems of individual well, extend pump detection period.But giving birth to
During product, often occur because Y-shaped connector and electric pump unit junction ball-and-seat fail to solve electric pump unit passage
Sealing problem, when double pump produces, lower face-pumping group intact and upper face-pumping group ball-and-seat is revealed, and causes the following unit cannot be normal
Produce.
Summary of the invention
This utility model provides a kind of Y for two-pump process tubing string to connect for solving technical problem present in known technology
Head, uses this joint can be greatly improved total effective run time of the double pumping systems of individual well, extends pump detection period.
This utility model is adopted the technical scheme that by solving technical problem present in known technology: a kind of be used for double pump
The Y-shaped connector of process pipe string, including the supervisor being interconnected and bypass pipe, is provided with ball-and-seat in described bypass pipe, described
Ball-and-seat includes that sealing drum, sealed steel ball and compression spring, described sealing drum are fixed in described bypass pipe, described close
Being formed with annular space between top and the described bypass pipe of sealed tube, described annular space connects, at described sealing drum with described supervisor
Upper portion side wall is provided with the flowing hole connected with described annular space, is formed with valve ball seat, described valve ball seat in described sealing drum
It is positioned at the lower section of described flowing hole, in described sealing drum, is provided with the sealed steel ball coincideing with described valve ball seat, described close
Sealing the compression spring that is arranged over of steel ball, described compression spring clamped at the upper end of described sealed steel ball and described bypass pipe it
Between.
Seating nipple on the upper end of described supervisor connects and has, connects in the lower end of described supervisor and has lower seating nipple.
The bottom of described sealing drum is stretched out outside the lower end of described bypass pipe, is provided with in the bottom of described sealing drum and adopts
The screw thread that oil electric pump connects.
Described flowing hole has multiple, and multiple described flowing holes are evenly arranged along the circumference of described sealing drum.
This utility model has the advantage that with good effect: uses the structure arranging ball-and-seat in bypass pipe, connects at Y
When head and electric pump unit junction ball-and-seat lost efficacy, it is possible to make the oil recovery passage of stopping production electric pump realize effectively and seal, solve double
When pump produces, the intact problem that cannot normally produce because revealing at upper pump group ball-and-seat in lower submersible electric pump pump group,
And then total effective run time of raising individual well pumping systems, extend pump detection period, reduce workman's workload, extend and produce
The normal production cycles of well, stable yields, the volume increase to producing well, there is the biggest facilitation.And this utility model seals
Reliably, simple in construction, and construction safety reliability height, strong operability, operation are simple, assembling and execute-in-place convenient.
Single Y-shaped connector two-pump process tubing string and double Y-shaped connector two-pump process tubing strings can be applicable to, be suitable to that hole condition is poor, well depth relatively greatly,
The oil well that production cycle is shorter, inspection pump is inconvenient.

Detailed description of the invention
For summary of the invention of the present utility model, feature and effect can be further appreciated that, hereby enumerate following example, and coordinate
Accompanying drawing describes in detail as follows:
Referring to Fig. 1 and Fig. 2, a kind of Y-shaped connector for two-pump process tubing string, including the supervisor 7 being interconnected and bypass
Pipe 2, is provided with ball-and-seat in described bypass pipe 2, and described ball-and-seat includes sealing drum 5, sealed steel ball 4 and compression spring
3, described sealing drum 5 is fixed in described bypass pipe 2, shape between the top and described bypass pipe 2 of described sealing drum 5
Become to have annular space 8, described annular space 8 to connect with described supervisor 7, the upper portion side wall of described sealing drum 5 is provided with and described ring
The flowing hole 9 of empty 8 connections, is formed with valve ball seat in described sealing drum 5, and described valve ball seat is positioned at described flowing hole 8
Lower section, in described sealing drum 5, be provided with the sealed steel ball 4 coincideing with described valve ball seat, upper at described sealed steel ball 4
Side is provided with compression spring 3, and described compression spring 3 clamps at described sealed steel ball 4 and at the upper end of described bypass pipe 2.
Above-mentioned Y-shaped connector can directly apply to double Y-shaped connector two-pump process tubing string.It is applied to double Y-shaped connector two-pump process tubing string
Time, entering down two Y-shaped connectors, the bypass pipe of each Y-shaped connector respectively hangs the electric pump unit of a platform independent, the master of Y-shaped connector
Pipe is as TCH test channel, and by steel wire operation or wireline operation, pulling in main pipeline produces blanking plug, test blanking plug,
Realize alternate run and the dynamic test of double pump.General first delivery lower Y-shaped connector production blanking plug, machine under then starting
Group produces, if upper unit ball-and-seat has leakage, then input separation sleeve is by upper Y-shaped connector oil-producing channel blockage, under restarting
Unit produces, and lower unit durability the most then, is restarted upper unit and produced.
When above-mentioned Y-shaped connector is applied to single Y-shaped connector two-pump process tubing string by needs, need in the upper end of described supervisor 7 even
Connect seating nipple 1, seating nipple 6 under the lower end of described supervisor 7 connects.When being applied to single Y-shaped connector two-pump process tubing string:
One Y-shaped connector hangs two set electric pump unit, successively enables bypass pipe, main siphunculus electric pump unit, to extend pump detection period,
First starting bypass pipe electric pump to produce, if main siphunculus ball-and-seat seals bad, then put into blanking plug and remedy, continuation starts other
Siphunculus electric pump produces.Extremely, then main siphunculus electric pump is started in the bypass pipe electric pump life-span；If bypass pipe ball-and-seat seals bad,
Then put into isolating cylinder to remedy, start main siphunculus electric pump and produce.Until the main siphunculus electric pump life-span is to the greatest extent, lift pipe string inspection pump.
In above-mentioned Y-shaped connector, the bottom of described sealing drum 5 is stretched out outside the lower end of described bypass pipe 2, described close
