Description
Technical field
The present invention relates to a kind of oil gas, water injection well underground operation tool, especially the multi-functional tail pipe valve of Operating Pressure.
Background technology
At present, the universal and utility ratio of oil-water well operation with pressure has obtained significant growth, oil-water well operation with pressure, and its advantage is not use well killing fluid to carry out operation, thus eliminates the potential pollution of hydraulic fluid for payzone.Carry out effective shutoff to tail pipe can ensure not put excessive operation, can protect operating environment, maintain region water injection pressure, reducing operation affects oil well output.And existing plugging device is because reasons in structure exists input, and to fish for success rate low, cost is high, lift pipe string not blowout prevention problem, influence zone force feed water well operation efficiency.
Summary of the invention
In order to solve existing plugging device, because reasons in structure exists input, to fish for success rate low, and cost is high, the problem of lift pipe string not blowout prevention.The invention provides the multi-functional tail pipe valve of a kind of Operating Pressure.This Operating Pressure multi-functional tail pipe valve have throw in fish for that success rate is high, blowout prevention of going into the well, water metaideophone, reacting cycle well-flushing and remake the feature of industry blowout prevention function.
Technical scheme of the present invention is: this Operating Pressure multi-functional tail pipe valve comprises top connection, middle cover, housing, transposition pin, spacer shell, valve seat, hyoplastron, joint ring and lower contact.Top connection lower end is connected with middle cover, spacer shell is connected with under middle cover, lower contact is connected with under spacer shell, housing is placed in cover, spring is equipped with under the outer ring boss of housing upper end, housing lower external face has continuous zigzag slideway, valve seat is placed in spacer shell, valve seat upper hinge is connected with hyoplastron, and hinge axis is equipped with torsion spring, and joint ring is placed in the step hole of lower contact upper end, housing upper end is spherical, housing upper portion side wall has through hole, has transposition pin in spacer shell top, and transposition pin the inner is placed in slideway.
The present invention has following beneficial effect: this Operating Pressure multi-functional tail pipe valve is connected with middle cover owing to adopting top connection lower end, spacer shell is connected with under middle cover, lower contact is connected with under spacer shell, housing is placed in cover, spring is equipped with under the outer ring boss of housing upper end, housing lower external face has continuous zigzag slideway, valve seat is placed in spacer shell, valve seat upper hinge is connected with hyoplastron, hinge axis is equipped with torsion spring, joint ring is placed in the step hole of lower contact upper end, housing upper end is spherical, housing upper portion side wall has through hole, transposition pin is had in spacer shell top, transposition pin the inner is placed in the structure in slideway.Utilize pitching add decompression process housing transposition is realized tubing string go into the well blowout prevention, remake the effect of industry blowout prevention function, the effect of anti-flushing well, after pitching, tubing string is just noting the effect realizing water metaideophone.Simplify endoporus shutoff at the bottom of next well in operation, reduce shaft bottom endoporus shutoff operating cost, construction technology is simple, reliable, and execute-in-place is convenient.The multi-functional tail pipe valve of this Operating Pressure has blowout prevention of going into the well, water metaideophone, reacting cycle well-flushing and remakes the feature of industry blowout prevention function thus.
accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present invention.
In figure, 1-top connection, overlaps in 2-, 3-housing, and 4-replaces pin, 5-spacer shell, 6-valve seat, 7-hyoplastron, 8-joint ring, 9-lower contact, 10-slideway.
detailed description of the invention:
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, this Operating Pressure multi-functional tail pipe valve comprises top connection 1, middle cover 2, housing 3, transposition pin 4, spacer shell 5, valve seat 6, hyoplastron 7, joint ring 8 and lower contact 9.Top connection 1 lower end is connected with middle cover 2, middle cover is connected with spacer shell 52 times, spacer shell is connected with lower contact 95 times, housing 3 is placed in cover 2, spring is equipped with under the outer ring boss of housing 3 upper end, housing 3 lower external face has continuous zigzag slideway 10, valve seat 6 is placed in spacer shell 5, valve seat 6 upper hinge is connected with hyoplastron 7, hinge axis is equipped with torsion spring, joint ring 8 is placed in the step hole of lower contact 9 upper end, housing 3 upper end is spherical, housing 3 upper portion side wall has through hole, transposition pin 4 is had in spacer shell 5 top, transposition pin 4 the inner is placed in slideway 10.
Sketch this Operating Pressure multi-functional tail pipe valve operating principle:
The multi-functional tail pipe valve of this Operating Pressure to be connected under tubing string on screen casing.
When lower tubular column, housing 3 is on top, and medium is by lower contact 9 entering tool, and hyoplastron 7 upwards overturns under the action of the spring, is shut by valve seat 6 internal channel, and well liquid by passage to ground, cannot play blowout prevention function at lower tubular column.
Water metaideophone function, precalculated position is arrived at lower well tool, pitching pressurization in oil pipe, housing 3 forehand is depressed into setting pressure to realize housing 3 and be displaced downwardly to bottom dead centre, the pin 4 that namely replaces is stuck in slideway 10 bottom dead centre, and housing 3 backs down hyoplastron 7 through joint ring 8, hyoplastron 7 cannot upwards be overturn, because water injection pressure is large, the steel ball of input is enclosed in housing 3 upper end, can the operation of water metaideophone.
During reacting cycle well-flushing, when pressurizeing in sleeve pipe, due to the steel ball jack-up that pressure reduction casing pressure will drop into, its housing 3 is up under spring force, housing 3 moves to mid point, and the pin 4 that namely replaces is stuck in slideway 10 mid point, and hyoplastron 7 still cannot upwards overturn, flushing fluid backs down steel ball and enters well-flushing in tubing string, thus realizes the function of sleeve pipe to the water filling of oil pipe reacting cycle.
When remaking industry blowout prevention, pitching pressurization in oil pipe, housing 3 forehand is depressed into setting pressure to realize housing 3 moves to top dead-centre, the pin 4 that namely replaces is stuck in slideway 10 top dead-centre, housing 3 leaves joint ring 8, and hyoplastron 7 upwards overturns, and is shut by valve seat 6 internal channel, well liquid by passage to ground, cannot play blowout prevention function at upper lifting pipe post.
If need again operation or Operating Pressure and production operation, repeat lower tubular column operation, the operation of water metaideophone, the operation of reacting cycle well-flushing, add decompression process by pitching and housing 3 to be replaced realization.
The multi-functional tail pipe valve of this Operating Pressure has multi-purpose valve, relative to conventional completed well valve, has lift pipe string blowout prevention function.Only need can realize into well blowout prevention, water metaideophone, reacting cycle well-flushing and the conversion remaking industry blowout prevention function by well head plus-minus pressure, this Operating Pressure multi-functional tail pipe valve is simple to operate.Simplify endoporus shutoff at the bottom of next well in operation, reduce shaft bottom endoporus shutoff operating cost, can realize Operating Pressure oil pipe column rise, under, ensure that Operating Pressure safely, alleviate operating worker difficulty of construction and prevent and environment pollution is caused to well site, avoid and use well killing fluid to carry out operation, thus eliminate the Latent destruction of pressure liquid for payzone and the potential safety hazard of operation.
