Description
Technical field
The present invention relates to a kind of fluid pressure type high temperature pumpingh well blowout preventer and application methods, belong to oilfield safe practice neck
Domain.
Background technology
The oilfield exploitation overwhelming majority is to extract Crude Oil out ground using pumping unit at present, and rod-pumped well relies on temporary guide base
Root box and rubber gate are sealed pumping well polish rod, since pumping well polish rod is influenced by alternating load for a long time, are easy to make
Polished rod can be caused to damage, oil field at polished rod steel fatigue along with to beat optical-rod clamp on polished rod during oil well operation
On often there is a phenomenon where pumping well polish rod is disconnected de-, light rod-broken length will result in polished rod when being more than more than polished rod side and fall into well
Interior, at this moment packing box and rubber gate just lose sealing function, and oil well is at runaway condition, when there are blowing abilities for oil well
When blowout will occur.During thickened oil recovery, steam injection is needed to reduce viscosity of crude, the oil well of steam injection exploitation is taken out due to turning
Initial stage oil temperature has blowing ability close to 100 DEG C, and when generation oil well polished rod is disconnected de-, high temperature crude oil will be from oil well disk
It is sprayed on root box, it is difficult to control.Due to currently without the dedicated blowout seal device of high-temperature oil well, when high-temperature oil well blowout, mostly uses
Manpower is inserted into waddy or metallic rod is sealed, and since heavy oil wells packing is mostly graphite or fluorubber packing, hardness is high, elastic
Difference, manpower is inserted into sealing bar can be highly difficult, adds high temperature crude oil splash, and manually going closure, there are prodigious risks, therefore very
It can not just be handled after more oil-well blowings, have to again be handled after oil well pressure reduction, will result in serious environment in this way
Pollution and property loss.
Invention content
For overcome the deficiencies in the prior art, a kind of fluid pressure type high temperature pumpingh well blowout preventer of present invention offer and user
Method.
Fluid pressure type high temperature pumpingh well blowout preventer, main hydraulic is very heavy, block plunger, plunger barrel, spray guard, fixed shoulder,
Packing box handle fixing groove, fixed pin composition.Internal thread is arranged at the plunger barrel top of the present invention, is connected by internal thread and hydraulic jack
It connects；Closure plunger is cylindrical structure, and top has external screw thread, lower part to have chamfering, hydraulic jack mandril center to have screw hole and block column
The external screw thread in portion is attached beyond the Great Wall；Plunger barrel lower part welds together with spray guard, and through-hole is arranged at spray guard top, can allow envelope
Stifled plunger passes through, and it is hatch frame that fixed shoulder, front, which are arranged, at spray guard lower part, and there are fixed pin holes in both sides, can plug in fixed pin
Enter.
A kind of application method of fluid pressure type high temperature pumpingh well blowout preventer, height is sleeved on by spray guard front opening by spray guard
On the packing box of warm oil well, oil-well packing box lower edge is blocked by spray guard lower fixed stage shoulder, by fixed pin, by fluid pressure type
High temperature pumpingh well blowout preventer is fixed on high-temperature oil well packing box, and will block plunger by hydraulic jack is pressed into oil-well packing box,
Achieve the purpose that block high-temperature oil well；Contain following steps；
At the blowout prevention cover opening back side, operation prevents high temperature crude oil splash from hurting sb.'s feelings to operating personnel；
As long as the packing box that blowout prevention cover opening is aligned to blowout oil well when blowout is pushed into, being inserted into two fixed pins can be to prevent
Only high temperature crude oil splash is hurted sb.'s feelings, if blowout is serious, when personnel can not be close, can be fixed fluid pressure type high temperature pumpingh well blowout preventer
Among stock, two operating personnel hold stock one end respectively, and oil well disk is inserted into from distant place by fluid pressure type high temperature pumpingh well blowout preventer
On root box, change the direction of high temperature crude oil splash using spray guard, then leans near operation again；
It uses hydraulic pressure for power, will be greater than the closure plunger indentation packing box of pumping well polish rod diameter, improve leakproofness, it is fast
Speed blocks high-temperature oil well.
It is different from background technology a little：
1, spray guard of the invention is single side hatch frame, and operating personnel can prevent high temperature crude oil in the operation of the opening back side
Splash is hurted sb.'s feelings, if blowout serious personal can not be close, fluid pressure type high temperature pumpingh well blowout preventer can be fixed among stock,
Two operating personnel hold stock one end respectively, are inserted on oil-well packing box from distant place by fluid pressure type high temperature pumpingh well blowout preventer, then
Near operation is leaned on again, and operation can not be just carried out when prior art blowout is serious.
2, the present invention is fixed using packing box for pumping well, easy to operate, can be carried out to high temperature and pressure pumpingh well
It is rapid to block.The prior art is mostly used to be bundled on production tree with steel wire rope, iron wire or iron chains after wooden stick or iron staff are inserted into and be carried out
Fixed, the prior art is difficult to solve when encountering high temperature and pressure oil well blowout.
3, the present invention uses hydraulic pressure for power, can will be greater than the closure plunger indentation packing box of pumping well polish rod diameter,
Leakproofness is improved, wooden stick or iron staff are inserted by the prior art using manpower, since heavy oil wells packing is mostly graphite or fluorubber disk
Root, hardness high resiliency is poor, and manpower is inserted into sealing bar can be highly difficult, adds high temperature crude oil splash, manually goes closure presence very big
Risk, therefore can not just be handled after many oil-well blowings, have to again be handled after oil well pressure reduction, can thus be made
At serious environmental pollution and property loss.
The effect of invention：
The present invention is fixed using packing box for pumping well, easy to operate, securely and reliably, can be pumped to high temperature and pressure
Well is blocked rapidly, and present invention tool is designed with spray guard, and spray guard is single side hatch frame, is designed using plug-in type, is operated
Simply, blowout can be quickly controlled, operation can prevent high temperature crude oil splash from hurting sb.'s feelings to operating personnel at the blowout prevention cover opening back side.Well
As long as the packing box that blowout prevention cover opening is aligned to blowout oil well when spray is pushed into, two fixed pins are inserted into it is prevented that high temperature crude oil
Splash is hurted sb.'s feelings, if blowout is serious, when personnel can not be close, fluid pressure type high temperature pumpingh well blowout preventer can be fixed in stock
Between, two operating personnel hold stock one end respectively, are inserted on oil-well packing box from distant place by fluid pressure type high temperature pumpingh well blowout preventer, profit
Change the direction of high temperature crude oil splash with spray guard, then leans near operation again.Heavy oil wells packing is mostly graphite or fluorubber packing,
Hardness high resiliency is poor, and manpower is inserted into sealing bar can be highly difficult, adds high temperature crude oil splash, and manually going closure, there are prodigious wind
Danger, therefore can not just be handled after many oil-well blowings, it have to again be handled after oil well pressure reduction, will result in this way
Serious environmental pollution and property loss.The present invention uses hydraulic pressure for power, can will be greater than the closure of pumping well polish rod diameter
Plunger is pressed into packing box, improves leakproofness, blocks high-temperature oil well rapidly.
