Description
Technical field
The utility model relates to a kind of fluid pressure type high temperature pumpingh well blowout preventer, belongs to oilfield safety technics field.
Background technology
The oilfield exploitation overwhelming majority utilizes oil pumper to extract Crude Oil out ground at present, rod-pumped well relies on wellhead packing box and rubber gate to seal pumping well polish rod, because pumping well polish rod is subject to the impact of fluctuating load for a long time, easily cause polished rod steel fatigue, add in oil well operation process and will on polished rod, beat optical-rod clamp, can cause damage to polished rod, on oil field, often can there is the disconnected de-phenomenon of pumping well polish rod, light rod-broken length exceedes polished rod side and will cause polished rod to fall in well when remaining, at this moment packing box and rubber gate have just lost sealing function, oil well is just in runaway condition, in the time that existing blowing ability, oil well will there is blowout.In thickened oil recovery process, need steam injection to reduce viscosity of crude, the oil well of steam injection exploitation approaches 100 ℃ owing to turning the initial stage oil temperature of taking out, and has blowing ability, and disconnected when de-when there is oil well polished rod, high temperature crude oil will spray from oil-well packing box, is difficult to control.Owing to there is no at present the special blowout seal device of high-temperature oil well, when high-temperature oil well blowout, manpower insertion waddy or the Metallic rod of adopting seal more, because heavy oil wells packing mostly is graphite or fluorubber packing, hardness is high, poor flexibility, manpower inserts seal bar can be very difficult, add high temperature crude oil splash, manually go shutoff to have very large risk, therefore after a lot of oil-well blowings, just cannot process, have to after oil well pressure reduces, process again, will cause so serious environment pollution and property loss.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of fluid pressure type high temperature pumpingh well blowout preventer.
A kind of fluid pressure type high temperature pumpingh well blowout preventer, there is packing box handle holddown groove spray guard both sides, fixing shoulder is arranged at spray guard bottom, and packing box handle holddown groove has through hole, can insert steady pin, through hole is arranged at spray guard top, welded top has plunger barrel, and screw thread is arranged at plunger barrel top, and plunger barrel is connected with hydraulic jack by screw thread, the push rod front end of hydraulic jack is connected with shutoff plunger by screw thread, and shutoff plunger can enter spray guard inside by plunger barrel and spray guard top through hole.
A kind of using method of fluid pressure type high temperature pumpingh well blowout preventer, spray guard is enclosed within on the packing box of high-temperature oil well by spray guard front opening, block edge under oil-well packing box by the fixing shoulder in spray guard bottom, pass through steady pin, fluid pressure type high temperature pumpingh well blowout preventer is fixed on high-temperature oil well packing box, by hydraulic jack, shutoff plunger is pressed into oil-well packing box, reaches the object of shutoff high-temperature oil well; Contain following steps;
Operating personnel prevent that in the spray guard opening back side operation high temperature crude oil splash from hurting sb.'s feelings;
When blowout, need only the packing box of spray guard opening aligning blowout oil well is pushed, insert two steady pins and just can prevent that high temperature crude oil splash from hurting sb.'s feelings, if blowout is serious, personnel cannot near time, fluid pressure type high temperature pumpingh well blowout preventer can be fixed in the middle of stock, two operating personnel hold respectively stock one end, from afar fluid pressure type high temperature pumpingh well blowout preventer are inserted on oil-well packing box, utilize the direction of spray guard change high temperature crude oil splash, and then near operation;
Employing hydraulic pressure is power, and the shutoff plunger that is greater than pumping well polish rod diameter is pressed into packing box, improves sealing, rapidly shutoff high-temperature oil well.
With background technology difference:
1, spray guard of the present utility model is opening one side mouth structure, operating personnel can prevent that in the opening back side operation high temperature crude oil splash from hurting sb.'s feelings, if the serious personnel of blowout cannot near time, fluid pressure type high temperature pumpingh well blowout preventer can be fixed in the middle of stock, two operating personnel hold respectively stock one end, from afar fluid pressure type high temperature pumpingh well blowout preventer is inserted on oil-well packing box, and then near operation, when prior art blowout is serious, just cannot carry out operation.
2, the utility model utilizes packing box for pumping well to be fixed, convenient to operation, can carry out rapid shutoff to HTHP pumpingh well.Prior art is bundled on production tree and is fixed with wire rope, iron wire or iron chains after adopting wooden stick or iron staff to insert more, and while running into the blowout of HTHP oil well, prior art is difficult to solve.
3, the utility model employing hydraulic pressure is power, the shutoff plunger that is greater than pumping well polish rod diameter can be pressed into packing box, improve sealing, prior art adopts manpower that wooden stick or iron staff are inserted, because heavy oil wells packing mostly is graphite or fluorubber packing, hardness high resiliency is poor, manpower inserts seal bar can be very difficult, add high temperature crude oil splash, manually go shutoff to have very large risk, therefore after a lot of oil-well blowings, just cannot process, have to after oil well pressure reduces, process again, will cause so serious environment pollution and property loss.
The utility model utilizes packing box for pumping well to be fixed, convenient to operation, safe and reliable, can carry out rapid shutoff to HTHP pumpingh well, the utility model tool is designed with spray guard, and spray guard is opening one side mouth structure, the design of employing plug-in type, simple to operate, can control fast blowout, operating personnel can prevent that in the spray guard opening back side operation high temperature crude oil splash from hurting sb.'s feelings.When blowout, need only the packing box of spray guard opening aligning blowout oil well is pushed, insert two steady pins and just can prevent that high temperature crude oil splash from hurting sb.'s feelings, if blowout is serious, personnel cannot near time, fluid pressure type high temperature pumpingh well blowout preventer can be fixed in the middle of stock, two operating personnel hold respectively stock one end, from afar fluid pressure type high temperature pumpingh well blowout preventer are inserted on oil-well packing box, utilize the direction of spray guard change high temperature crude oil splash, and then near operation.Heavy oil wells packing mostly is graphite or fluorubber packing, hardness high resiliency is poor, manpower inserts seal bar can be very difficult, add high temperature crude oil splash, manually go shutoff to have very large risk, therefore after a lot of oil-well blowings, just cannot process, have to after oil well pressure reduces, process again, will cause so serious environment pollution and property loss.It is power that the utility model adopts hydraulic pressure, the shutoff plunger that is greater than pumping well polish rod diameter can be pressed into packing box, improves sealing, rapidly shutoff high-temperature oil well.
