Description
Technical field
This utility model relates to oilfield, a kind of well mouth of oil well release guiding device.
Background technology
In oilfield process, during the construction of all kinds of well heads, need to be put by bottom pressure only, particularly in the case of casing pressure is higher, enter oil return pipeline by well head fixed pressure air releasing valve door row, need the long period, affect construction speed.Down-hole casing pressure bleeds off pressure slowly essentially from two aspects at present: 1, level pressure air-bleed latus rectum is less: proof wellhead oil casing flow process is mainly connected by level pressure air-bleed valve, during normal production, level pressure air-bleed valve is by spring and press-fit under screw thread, it is achieved enter oil return flow process outside fixation pressure.Owing to this passage is most, below 30 millimeters, handling capacity is poor, simultaneously because spring effect, passage is opened limited, and build-up of pressure is by slowly.2, level pressure air-bleed channel blockage: based on by gas when level pressure air-bleed passage normally produces, and flow is less.During long-term production, due to reasons such as this passage fouling, wax deposition, causing by narrow, fluid handling capacity is deteriorated, and causes and bleeds off pressure time lengthening.
Summary of the invention
In order to overcome the deficiency that existing well mouth of oil well release is slow, bleed off pressure time length, this utility model provides a kind of well mouth of oil well release guiding device, and this well mouth of oil well release guiding device is connected by tubing and casing valve, it is achieved the purpose of casing pressure quick drain.
The technical solution of the utility model is: a kind of well mouth of oil well release guiding device, including clip seat, folded tube A is connected by three width formula swivel joint C on described clip seat, the other end of folded tube A connects three width formula swivel joint A, on described three width formula swivel joint A, connection has folded tube B, the other end of folded tube B connects tuningout ball by three width formula swivel joint B, and described tuningout ball is placed in tuningout clip seat, and passes through mating spherical surfaces between tuningout ball and tuningout clip seat；On three described width formula swivel joint A, connection has pressure obtaning device.
It is provided with the pressure cap being matched therewith outside described tuningout ball, and pressure cap bottom is threadedly attached on tuningout clip seat, is provided with sealing ring B between described tuningout ball and tuningout clip seat.
Connect on described pressure obtaning device and have Pressure gauge.
The end of described three width formula swivel joint B and three width formula swivel joint C is respectively connected with end cap.
In described folded tube B, connection has atmospheric valve.
This utility model has the advantages that owing to taking such scheme, this device is connected by three three width formula swivel joints, two clip distance between seats and clip seat axis can be regulated, realize axis tuningout, thus oil jacket valve is connected, realization carries out casing pressure quick drain, changes and entered oil return pipeline by well head fixed pressure air releasing valve door row in the past, bleeds off pressure the present situation of time length.

Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings:
By shown in Fig. 1 to Fig. 5, a kind of well mouth of oil well release guiding device, including clip seat 1, on described clip seat 1, elbow connects three width formula swivel joint C15, connected by overcoat 12 on three width formula swivel joint C15 and have folded tube A7, make folded tube A7 the most free to rotate with clip seat 1.The other end of folded tube A7 connects three width formula swivel joint A10 by another overcoat, and described three width formula swivel joint A10 are connected by elbow folded tube B16, and such folded tube B16 and folded tube A7 are free to rotate.The other end of described folded tube B16 connects three width formula swivel joint B14 by elbow, the three width formula swivel joint B14 other ends connect tuningout ball 5 by overcoat 12, described tuningout ball 5 is placed in tuningout clip seat 2, by being provided with sealing ring B13 between mating spherical surfaces, and tuningout ball 5 and tuningout clip seat 2 between tuningout ball 5 and tuningout clip seat 2.Described tuningout ball 5 is outside is provided with the pressure cap 4 being matched therewith, and pressure cap 4 top is stuck in edge on tuningout ball 5, and pressure cap 4 bottom is threadedly attached on tuningout clip seat 2, thus by spacing for tuningout ball 5.On three described width formula swivel joint A10, connection has pressure obtaning device 11, and pressure obtaning device 11 connects Pressure gauge 8, for monitoring the change of pressure in operating process.The end of described three width formula swivel joint B14 and three width formula swivel joint C15 is respectively connected with end cap 3, and is sealed by sealing ring A9；In described folded tube B16, connection has atmospheric valve 6, is vented before provision for disengagement.
Two parts that at the three of this well mouth of oil well release guiding device, three width formula swivel joints are connected all can realize 360 degree of rotations, such that it is able to regulation two clip distance between seats and clip seat axis, clip seat in side is tuningout clip seat 2 simultaneously, by coordinating with tuningout ball 5, can realize axis tuningout.During bleeding off pressure, first side hoop 1 is connected with well mouth oil pipe valve, then regulation other side tuningout clip seat 2 spacing, then regulates clip axis by tuningout ball 5, coincide with wellhead casing pipe valve hoop plane, then be attached by clip.Open oil pipe and sleeve valve after connection respectively, sleeve pipe inner high voltage is entered in oil pipe, it is achieved bleed off pressure operation.
