Abstract
The utility model provides an annular preventer with internal circulating water cooling, and relates to the field of manufacturing of oil and gas extraction devices of oil and gas fields. According to the annular preventer, creative design is carried out on shaft mouth sealing and safety protective mechanisms, and the problem that viscosity of hydraulic oil in an annular preventer body is reduced when the temperature of the hydraulic oil is higher than a rated working temperature due to high temperature of gas extraction, and leakage and pressure reduction occur is solved. A circulating water cooling system with low water inlet level and high water outlet level is arranged in the annular preventer, and circulating water is used for lowering the temperature of the annular preventer body. The annular preventer has the advantages of being ingenious and compact in structure, good in heat absorption effect, capable of guaranteeing that the hydraulic oil normally works at a rated working temperature, capable of prolonging the service life of a rubber core, sensitive in action when the preventer is closed, reliable in closing, and capable of eliminating accident potential caused by high temperature.
Description
Technical field
The utility model relates to oil, gas field oil recovery, gas equipment, be specifically related to a kind of annular preventer of built-in recirculated water cooling, annular preventer is a requisite transitional facility in the time of closing well, in order to seal the instruments such as the drilling rod, tool joint, drill collar, sleeve pipe of various shape and size, when in well during without drilling tool, also can the totally-enclosed well head of short-term, annular preventer is aboveground operation and important well head safe device while changing downhole tool.
Background technology
In gas production operation process, annular preventer is normally open, in body Vertical Channel, there is flowline to pass through, the built-in piston of annular preventer and glue core, when pistons work, rely on the hydraulic oil with proper viscosity that power is provided, glue core is the centripetal shrinkage strain of energy under piston promotes, the annular space of available a kind of glue core sealing different size, present situation is that stratum high-temperature reaches the gas of 300 ℃ when the annular preventer, can pass to preventer body amount of heat, make body in the condition of high temperature, the hydraulic oil of driven plunger is owing to exceeding that specified operating temperature is thinning and viscosity declines in body, not only can leak, and can produce step-down phenomenon, while requiring to close annular preventer immediately once stratum high pressure produces well kick and gas blowout accident like this, can because of leak or step-down make piston action slow even malfunctioning, can not drive the centripetal contraction of glue core that annular preventer was lost efficacy, it is aging that while high temperature also makes glue core be easy to, there is great accident potential in whole production.
Summary of the invention
The purpose of this utility model is to provide a kind of annular preventer of built-in recirculated water cooling, mainly solve annular preventer in the time of gas production operation, be easy to aging because body high temperature makes hydraulic oil viscosity decline and glue core, thereby the major accident hidden danger that preventer lost efficacy, now change into the built-in circulating water cooling system of body, reduce body temperature with recirculated water, hydraulic oil is normally worked under specified operating temperature and extend glue core application life.
The utility model effectively reduces annular preventer complete machine temperature in use, while closing preventer, is active in one's movements, and closes reliably, has eliminated the accident potential that Yin Gaowen brings.
The purpose of this utility model realizes with following technical scheme: the annular groove of processing a square-section in annular preventer inner body wall, and design a capping, connect and be equipped with fluorine rubber ring sealing with screw, make to form between body and capping a toroidal cavity, as recirculated water endothermic water tank, inside there are the water deflector of going out and water outlet vertical tube; Process two holes in body bottom and hydraulic oil enters, spill port is perpendicular section, as endothermic water tank into and out of hole, wherein in weep hole, there is water outlet transverse tube, realize that recirculated water low water stage is entered, high water level goes out, to fully absorb annular preventer body heat.
Being expressed as of technical solutions of the utility model general introduction: a kind of annular preventer of built-in recirculated water cooling, it is characterized in that: the annular groove of processing a square-section in annular preventer inner body wall, and design body capping, connect and be equipped with fluorine rubber ring sealing with screw, make to form a toroidal cavity between body and body capping, in cavity, have the water deflector of going out and water outlet transverse tube.
The beneficial effects of the utility model are delicate structure, compactness, and endothermic effect is good, and preventer body temperature can drop to hydraulic oil nominal operation temperature, have extended glue core application life, have eliminated the accident potential that Yin Gaowen brings.

The specific embodiment
The utility model is shown embodiment by its operating principle.In gas production operation process, annular preventer is normally open, in preventer body 2 Vertical Channel, have flowline to pass through, the built-in piston 10 of annular preventer and glue core 15, in the time that needs are closed preventer, oil-in 17 oil-feeds, oil return opening 18 oil returns, piston 10 moves under hydraulic oil effect, promotes glue core 15, glue core 15 can only do centripetal shrinkage strain under top cover 16 hinders, thus the Vertical Channel in sealing blowout-preventing body 2.
Stratum high-temperature reaches the gas of 300 ℃ when the annular preventer, can pass to preventer body 2 amount of heats, make preventer body 2 in the condition of high temperature, because temperature rising is thinning, viscosity declines the hydraulic oil of the interior driven plunger 10 of preventer body 2, not only be easy to leak, and the hydraulic pressure producing declines.
The utility model is processed the annular groove of a square-section at annular preventer body 2 inwalls, and design body capping 13, being equipped with fluorine rubber ring 12 with screw 11 connections seals, make to form a toroidal cavity between preventer body 2 and body capping 13, as recirculated water endothermic water tank, in cavity, there are the water deflector of going out 3 and water outlet transverse tube 6; Process two holes in preventer body 2 bottoms and hydraulic oil oil-in 17, the perpendicular section of oil return opening 18, as endothermic water tank's water inlet 1 and delivery port 9; Going out water deflector 3 is welded by water outlet base 4 and water outlet vertical tube 5, water outlet transverse tube 6 is through weep hole, the inner is connected on water outlet base 4 by gas thread, outer end is sealed and is compressed by airtight and watertight padding 7 by delivery port briquetting 8, although water inlet 1 and delivery port 9 are in same level like this, but realize that recirculated water low water stage is entered, high water level goes out, can fully absorb annular preventer body 2 heats.
