Abstract
The utility model relates to an oil well head device. The technical proposal is as follows: a bearing gland, a bearing box, a screw rod, a ram shaft, a half-sealed side door and a half-sealed ram assembly are symmetrically distributed on the left side and the right side of the lower part of a shell; a fully-sealed valve seat, a fully-sealed valve plate, a valve stem and a fully-sealed side door are distributed at the upper part of the shell in the radial direction. The device is characterized in that the half-sealed ram axis of a double-ram preventer and the axis of a fully-sealed ram form an angle of 90 degrees, so that the preventer is lower, lighter and convenient to be operated. The fully-sealed ram is a whole steel structure, shortens the shut-in time and is sealed reliably. The lower connector of a jetting tool is provided with combined oil pipe thread, and applicable to two different pipe strings. During use, the jetting device can seal a plurality of pipe strings without replacing the half-sealed ram. The upper connector of the jetting tool is provided with a handle which is convenient for quick buckling. The upper end of the jetting tool is provided with a one-way valve used to control well blowout.
Description
Technical field:
The utility model relates to the well mouth of oil well device, and this device is mainly used in the workover treatment process, when gas blowout accident takes place, can close well head rapidly, the control blowout.
Background technology:
The used preventer of oil well repairing operation mostly is single ram type perventer at present, be applicable to the workover treatment of the oil pipe tubing string oil well that adopts same diameter, development along with petroleum drilling technology, deep-well, ultradeep well is more and more, the oil well ratio of combined string rises significantly, be that larger-diameter oil pipe is adopted on top, the oil pipe of minor diameter is adopted in the bottom, as adopt single ram type perventer, when lower tubular column, need the on-the-spot sealing of changing the suitable different tube diameters of flashboard to need, and the on-the-spot flashboard difficulty of changing, in case blowout takes place, owing to can not in time change flashboard, cause potential safety hazard.And the side door of double ram type preventer is all in a side, if when blowout takes place, can only could operate with special tool, and the closed-in time is long, inconvenient operation.
The utility model content:
The purpose of this utility model is to provide the preventer of a kind of suitable composite oil pipe tubing string workover treatment, and the scene need not to change the sealing that flashboard can be guaranteed the different tube diameters oil pipe, and simple in structure, easy to operate.
The technical solution of the utility model is: the lower housing portion bilateral symmetry is distributed with bearing gland, bearing box, screw mandrel, flashboard axis, partly seals side door and partly seal the flashboard assembly, and housing top radial distribution full envelope valve seat, sealed valve plate, valve rod and seal side door entirely entirely.
This device device also comprises the spray instrument of being made up of lower contact, tube connector, top connection and non-return valve of robbing.In the top connection of robbing the spray instrument, be provided with handle.
Its characteristics: the axis that partly seals flashboard axis and blind rams of double ram type preventer makes the height of preventer reduce weight saving, and handled easily mutually at an angle of 90.Blind rams is whole steel work, the closed-in time is shortened, and sealing is reliable.The lower contact of robbing the spray instrument is provided with the combination tubing round thread, is applicable to two kinds of different tubing strings.This blowout control device does not in use need replacing partly to seal flashboard just can realize sealing multiple tubing string.The top connection of robbing the spray instrument is provided with handle, is convenient to go up fast button.One way valve is equipped with in the upper end of robbing the spray instrument, is used to control blowout.
Description of drawings:
Fig. 1 is the utility model master TV structure figure; Fig. 2 is the left view of this Fig. 1; Accompanying drawing 3 is structure charts of robbing the spray instrument.
The specific embodiment
With reference to accompanying drawing 1, be distributed with bearing gland 1, bearing box 2, screw mandrel 3, flashboard axis 4, partly seal side door 5 and partly seal flashboard 7 assemblies in housing 6 bottom bilateral symmetry.With reference to accompanying drawing 2, housing 6 tops one side radial distribution full envelope valve seat 8, is sealed valve plate 9, valve rod 10 and seal side door 11 entirely entirely.With reference to accompanying drawing 3, rob the spray instrument by lower contact 16, tube connector 15, top connection 14 and non-return valve 13, handle 12.
When gas blowout accident takes place, there is not tubing string in the well, can rotate full envelope valve rod 10, seal valve plate 9 entirely and advance, close preventer, realize shut-in well.When in the well tubing string being arranged, will rob the spray instrument rapidly and be installed on the oil pipe, promote tubing string, will rob the spray tool seat to pipe elevator, both sides are rotary screw rod 3, valve shaft 4 simultaneously, drives partly to seal flashboard assembly 7 and advance, and closes preventer, realizes shut-in well.
Claims (3)
1, the quick blowout control device of well head, the lower housing portion bilateral symmetry is distributed with bearing gland, bearing box, screw mandrel, flashboard axis, partly seals side door and partly seal the flashboard assembly, it is characterized in that: housing top radial distribution full envelope valve seat, is sealed valve plate, valve rod and seal side door entirely entirely.
2, the quick blowout control device of well head according to claim 1 is characterized in that: also comprise the spray instrument of being made up of lower contact, tube connector, top connection and non-return valve of robbing.
3, the quick blowout control device of well head according to claim 2 is characterized in that: be provided with handle in the top connection of robbing the spray instrument.
