Abstract

The invention discloses an annular preventer shell. The annular preventer shell is characterized in that a manufacturing technology of the annular preventer shell includes the following steps that the shell is cast and molded through 4Crl0Si2Mo alloy steel which mainly includes alloy elements of carbon steel, silicon steel, manganese, molybdenum and chromium and non-alloy elements of boron and nitrogen; the alloy elements and the non-alloy elements are mixed and forged to form the 4Crl0Si2Mo alloy steel; and glass reinforced plastic is added on the basis to serve as an anticorrosive material, and the glass reinforced plastic and the 4Crl0Si2Mo alloy steel are subjected to hot quenching heat treatment to be cast and molded. According to the annular preventer shell, the 4Crl0Si2Mo alloy steel serves as the main material of the shell and has high heat resistance, even density and high water pressure resisting capability, so that the phenomena of cracking and the like of the preventer shell in the working process are effectively prevented after heat treatment; manufacturing is simple, and cost is low; and the material resistant to abrasion and corrosion is added, and therefore the service life is long.

Description

A kind of annular preventer housing
Technical field
The present invention relates to mechanical field, particularly relate to a kind of annular preventer housing.
Background technology
Ring jet-preventing device for drilling well is equipment indispensable in petroleum and natural gas drilling engineering, should possess effectively close well head, blowout and process the functions such as other complexcase when preventing drilling well, and possess the function with hydro valve flashboard.Housing is the main body of ram preventer, is the strength member bearing high pressure.Annular preventer is equipped with the Gate of ram-type preventer usually, the annular space of a sealing can be formed during running between tubing string and pit shaft, when there is no tubing string in well, also can complete shut-in well separately, but use several times just dying, and do not allow long-term closing well to use.
Preventer hull shape is comparatively complicated, geometrical variations is large, at the scene in open and close well process, easily there is formation of crack at region of stress concentration in the repeated stock effect that its inside is subject to high-pressure oil gas, and ftracture under repeated load, even brittle rupture, so reasonably select to seem quite crucial for annular preventer case material.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of annular preventer housing, and can effectively prevent preventer housing from occurring the phenomenons such as cracking in the course of the work, even density, hydraulic pressure resistance ability is strong.
The technical scheme that the present invention adopts is: provide a kind of annular preventer housing, it is characterized in that, its manufacture craft is as follows: described housing selects 4Cr10Si2Mo steel alloy casting, its component mainly comprises: carbon steel, silicon steel, manganese, molybdenum and chromium are as alloying element, boron and nitrogen are as non-alloyed element, described alloying element is formed 4Cr10Si2Mo steel alloy with non-alloyed element mixing enure, adds again a kind of impregnating material and 4Cr10Si2Mo steel alloy on this basis through quench hot thermal treatment casting.
Further, described impregnating material mainly glass reinforced plastic.
Further, described quench hot temperature is 1010 ~ 1050 DEG C.
The invention has the beneficial effects as follows: a kind of annular preventer housing of the present invention, 4Cr10Si2Mo steel alloy is adopted to have higher heat resistance as the main raw of housing, even density, hydraulic pressure resistance ability is strong, through Overheating Treatment, effectively prevent preventer housing from occurring the phenomenons such as cracking in the course of the work, manufacture simple cost low, add again the corrosion-resistant long service life of material wear-resistant.
Embodiment
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
A kind of annular preventer housing of the present invention, it is characterized in that, its manufacture craft is as follows: described housing selects 4Cr10Si2Mo steel alloy casting, even density, hydraulic pressure resistance ability is strong, its component mainly comprises: carbon steel, silicon steel, manganese, molybdenum and chromium are as alloying element, boron and nitrogen are as non-alloyed element, a part enters in solid solution liquid with atomic condition, another part forms Composite carburization body, described alloying element is formed 4Cr10Si2Mo steel alloy with non-alloyed element mixing enure, add again glass reinforced plastic on this basis as impregnating material and the 4Cr10Si2Mo steel alloy quench hot thermal treatment casting through 1010 ~ 1050 DEG C, effectively prevent region of stress concentration in the course of the work from occurring formation of crack, or ftracture under repeated load, even brittle rupture phenomenon.
The present invention adopts 4Cr10Si2Mo steel alloy to have higher heat resistance as the main raw of housing, even density, hydraulic pressure resistance ability is strong, through Overheating Treatment, effectively prevent preventer housing from occurring the phenomenons such as cracking in the course of the work, manufacture simple cost low, add again the corrosion-resistant long service life of material wear-resistant.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
