Abstract
The invention relates to a manual multifunctional thermal production blowout preventer. The body is formed by forging alloy steel, die cavities of each layer are perforated on all sides, and each layer is provided with two flashboards. A seal receptacle is respectively welded at the joints of the upper walls of the upper inner cavity and the lower inner cavity of the body and the flashboards. Whenthe flashboards move to the inner cavities of the body, a rubber sealing member on the upper end of each flashboard is in interference contact with the seal receptacle. The blowout preventer of the type contains closed specifications of various dimensions of oil pipes, so when different specifications of oil casing pipes are required to be sealed during the use, the flashboards and a sealing member do not need to be detached and changed; moreover, compared with a common single-flashboard blowout preventer of the same type, the weight and height are greatly reduced, thereby bringing great convenience to the operation of workers at the production line of an oil field and ensuring the work efficiency. Moreover, the blowout preventer has simple structure and convenient use, thereby being suitable for being popularized in each big oil field.
Description
Affiliated technical field
The present invention relates to a kind of manual ram preventer, belong to industrial gas oil drilling well and oil production equipment and drill through equipment technical field.
Background technology
The thermal recovery ram preventer is the oil field in completion practice, workover treatment and removes and stop the stratum high pressure gas to carry the well kick that crude oil and water may form and the generation of blowout secretly in oil pipe operation, oil recovery, the formation testing process, is installed in the safety sealing device of thermal production well mouth for preventing well kick, blowout.It is aboveground operation and requisite well head safe device when switching downhole tool.
The common manual ram preventer is formed by body, side door assembly, flashboard assembly three parts.Every layer of ram preventer all has an auxiliary gate-board at corresponding die cavity two ends, and the body die cavity adopts ellipsoidal structure, and the flashboard assembly is made up of preceding seal, top seal, flashboard body, and the locking leading screw connects lock shaft.
When abnormal conditions took place in the down-hole, manually preventer rotation lock leading screw promoted flashboard and cuts out the sealing oil casing annular space;
Common double-deck manual brake plate preventer is generally highly higher, and weight lays particular stress on, and process is numerous and diverse during sealing different model oil pipe dismounting and change, has influenced operating efficiency greatly.Oil field one line operating personnel requires manufacturer can develop new preventer to address the above problem.
Summary of the invention
The scheme that the present invention solves this technical problem is:
The whole domestic four flashboard double-deckers of developing at first of preventer, every stratotype chamber all around connects, every layer of flashboard that two pairs of different sizes are installed.The ellipse that the body die cavity changes common ram preventer is a rectangular configuration, is more suitable for the installation of four flashboard structures.
Lower inner cavity upper wall and flashboard joint are welded the embedding seal receptacle respectively on body.Flashboard is when the chamber body central motion, conflict with the seal receptacle interference in flashboard packing unit upper end, the semicircle rubber concave surface in front end center moves to the center simultaneously, holds the oil pipe of different size tightly, play the effect of sealing well head, seal chamber flashboard assembly plays full shut-in well mouth when move at the center effect entirely.
The preventer material all adopts alloy steel to forge and forms, and effectively reduces whole height and weight.The technical problem that this structure mainly solves is
Because every layer has two width of cloth flashboards, the oil pipe sealing specification that comprises various sizes, its function is more comprehensive, when in use needing to seal the oil pipe of different size, need not dismounting and change flashboard and seal, seal uses the material of special molecular structure to make, and can bear-18 ℃-149 ℃ temperature, the temperature rank reaches BE, and the limiting temperature of high low temperature and sealing performance all can satisfy the oil well environmental requirement fully.
This model preventer has increased by two width of cloth flashboards, but employing double-decker, the type hand height has only 440mm, weight is 405Kg, only is equivalent to 2/3 of the common preventer of same model, for shop floor worker operation in oil field brings very big convenience, guaranteed operating efficiency, and simple in structure, easy to use, be suitable at each elephant and promote.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing and example.

" O " type rubber seal, 9. interior hexagonal cylinder head bolt, 10. lock shaft, 11. side doors, 12. pad, 13. thrust ball bearings, 14. glands, 15. the locking leading screw, 16. sign of direction.
The specific embodiment
Below in conjunction with description of drawings, be explained in detail by example:
Fig. 1, when needing the oil pipe A of certain specification of sealing, during preventer work, place two 4 flashboard assemblies in the 6 body die cavities to move to the well head center by artificial rotation 10 lock shafts with oil pipe A correspondingly-sized, produce strength translation forward simultaneously, make two 5 caulking gum contacts hold oil pipe A and extruding generation slight deformation tightly, 5 caulking gums contact and push the generation slight deformation with 6 body flashboard cavity walls simultaneously, because the band that 5 caulking gums constitute seals, at this moment, 4 flashboard assemblies form the initial sealing of preventer upside well head.
When needs seal the oil pipe B of another model, do not need to dismantle flashboard as common preventer, change caulking gum, the 4 flashboard assemblies that directly withdraw from a certain specification are to initial position, 4 flashboard assemblies of rotation and oil pipe B correspondingly-sized just can be finished Seal Oil pipe ring shape space by normal running then.
When needs are shunt in a well, directly rotate both sides full envelope 4 flashboards by common ram preventer, can finish full shut-in well mouth.
