Abstract
The utility model discloses a hydraulic spew-rescue for the oil well in the petroleum industry applied to stop the spew of the well liquid in the well operation procedure, which is composed of a hydraulic locking organ and a blockage organ. The hydraulic locking organ is sleeved in the blockage organ, and the device is sleeved on the hoop of the wellhead. When the liquid is spewing within the well, the product can be rapidly arranged on the wellhead to validly stop the blowout and avoid the loss of the original oil and loss of life and personal injury with a high safety. The utility model is of a simple structure and a low production cost, which can rescue the blowout timely and provides obvious economical and social benefits.
Description
Technical field
The utility model relates to the downhole operation equipment of petroleum industry, and particularly a kind of oil water well hydraulic blowout control device prevents well liquid to gush when being used for oil, well job execution.
Background technology
The oil of petroleum industry, well are when workover treatment, and producing well particularly, the producing well borehole pressure that has raise suddenly sometimes, have little time to install control head, and borehole fluid just begins to be sprayed onto ground.As untimely installing wellhead control device, gas blowout accident will take place, cause great life and property loss.The producing well that has is in production or stopping production process for a long time, wellhead assembly is impaired, regulating gate fits badly, cause well head four-way bypass thorn to leak, gas blowout accident takes place, or owing to the destruction of thief to wellhead assembly, by-pass valve control is stolen, after borehole pressure raises, well head crude oil out of control also can occur and run off, gas blowout accident takes place.The on-the-spot at present control head complex structure that uses, function is low, thick heaviness is installed inconvenience, causes danger easily in the installation process, bad adaptability, set-up time is long, can not in time control well head, does not satisfy the requirement of robbing spray fast, occur gas blowout accident easily, cause the economic loss that to estimate.
Summary of the invention
The purpose of this utility model is a kind of oil water well hydraulic blowout control device of design, can be installed in well head quickly and easily when blowout occurring or the blowout sign is arranged, and in time the control well mouth pressure is prevented blowout.Avoid the crude stream environment pollution of becoming estranged, avoid casualties, improve the safety of operation field, reduce economic loss and protection environment.
The present technique solution can reach above-mentioned purpose: a kind of oil water well hydraulic blowout control device, comprise hydraulic locking mechanism and blockage mechanism, and the outer suit hydraulic locking mechanism of blockage mechanism is sleeved on this device on the well head clip head.
The beneficial effects of the utility model are: this apparatus structure is simple, low cost of manufacture, and is quick and easy for installation.When having fluid to gush out in the well, can effectively control and prevent blowout, avoid the crude stream casualties of becoming estranged, safe.Owing to can in time rob spray, avoided the crude oil loss also to protect environment, have tangible economic benefit and social benefit.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with embodiment the utility model is done further detailed description: referring to accompanying drawing, a kind of oil water well hydraulic blowout control device comprises hydraulic locking mechanism and blockage mechanism, and the outer suit hydraulic locking mechanism of blockage mechanism is sleeved on this device on the well head clip head 1.Blockage mechanism comprises blockage body 6, piston component 8 and plug 11, and piston component 8 is installed in the blockage body 6, and plug 11 is installed in the top of piston component 8.The bottom cylindrical of blockage body 6 has screw thread to be connected with hydraulic locking mechanism.Circle is provided with interior platform in blockage body 6 bottoms, and the platform lower surface is provided with the lock dog groove within it, and lock dog is installed.This lock dog is connected and fixed the Nei Tai lower surface of blockage body 6 and the upper surface of well head clip head 1.Blockage body 6 lower case are provided with lock ball by the hole, and central enclosure is provided with open flow outlet opening 7, and this open flow outlet opening 7 is arranged on the interior platform top of circle in blockage body 6 bottoms.Blockage body 6 upper body are provided with stop screw hole and pressure transmission mouth, and stop screw is installed in the stop screw hole, at the pressure transmission mouth liquid inlet joint 10 are installed.Retaining spray plate 9 is installed in the top of the open flow outlet opening 7 of blockage body 6, and its effect is to prevent liquid stream direct projection injury operator.Piston component 8 comprises piston body and seal, and the bottom of piston body is taper, and its middle part piston body is provided with seal.Piston component 8 is installed in the below of blockage body 6 upper body pressure transmission mouths, and the stop screw that its upper piston body is provided with in axial notch and blockage body 6 upper body cooperates.Hydraulic locking mechanism comprises lock tube 4, pressure transmission cover 5, tapered sleeve 3 and lock ball 2, and lock ball 2 and tapered sleeve 3 are installed in the lock tube 4, on adorn pressure transmission cover 5.Tapered sleeve 3 is installed in the top of lock ball 2, and circle is the inner conical structure in the bottom of cone, is convenient to promote lock ball 2, and its top cone is provided with sealing ring.Pressure transmission cover 5 is provided with axially extending bore, on the top of its axially extending bore the hydraulic locking liquid inlet joint is installed.When oil-water well need be installed the utility model, the blockage body 6 of this device is set on the well head clip head 1 of oil, well.Well head clip head 1 is positioned at the flank of well head big four, and after the installation, this device is parallel to the ground.This device in the accompanying drawing is to place vertically, and parallel to the ground in actual the use.The interior liquid stream of well this moment flows out from well head clip head 1, discharges by the open flow outlet opening on the blockage body 67, and the pressure in the blockage body 6 can not raise.From the hydraulic locking liquid inlet joint pumping liquid of pressure transmission cover 5, promote tapered sleeve 3 and move ahead, tapered sleeve 3 promotes lock ball 2 and moves to the inside, enters the below of well head clip head 1 cylindrical boss, thereby the utility model and well head clip head 1 are fixed into one.And then from liquid inlet joint 10 pumping liquids, promote piston component 8 and move ahead, piston component 8 is entered stop up its passage in the well head clip head 1, thereby the sealing well head is in time prevented blowout.
