Abstract
The invention discloses a blowout preventer shell which is characterized by being a rectangular ultrahigh-pressure blowout preventer shell, wherein a plurality of side holes are formed in the shell; the shell is of a double-shell material structure made of 25CrNiMo low-carbon alloy steel and is forged in a quenching and tempering heat treatment way; weight-reduced reinforcing ribs are cast outside the shell; and an anticorrosive paint layer is smeared inside the shell. The blowout preventer shell disclosed by the invention has relatively high yield strength, tensile strength and fatigue strength because of being made of 25CrNiMo low-carbon alloy steel and also has plasticity and toughness; the side holes formed in the shell can be used for throttling and releasing pressure, so that the safety performance is high; and an anticorrosion paint is smeared on the surface of the shell, so that the service life of the blowout preventer is favorably prolonged, and the blowout preventer is high in comprehensive performance and very high in economic benefit.
Description
Technical field
The present invention relates to mechanical field, particularly relate to a kind of preventer housing.
Background technology
Preventer is for cutting out well head in the operation process such as formation testing, well workover, completion, preventing gas blowout accident from occurring, by envelope and half envelope, two kinds of functions are integrated entirely, there is structure simple, easy to operate, the feature such as high pressure resistant is the security seal wellhead assembly preventing blowout that oil field is commonly used.
Housing is the main body of preventer, it is the strength member bearing high pressure, preventer housing requires to carry out high pressure and leak test, therefore, shell steel casting should be the steel-casting of high-quality, should not adopt chill, if use chill, the quality of steel-casting then can be made lower than normal steel casting part quality, the target of sound steel castings can not be reached.Current market is exactly that Enterprise Development must follow this principle, and the exploitation of the preventer housing of super-pressure has very profound significance to market premised on " based on the quality of product, product variety is various turns to developing direction ".
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of preventer housing, can throttling pressure release, and security performance high plasticity is large.
The technical scheme that the present invention adopts is: provide a kind of preventer housing, it is characterized in that, described preventer housing is a kind of preventer housing of super-pressure, shape is rectangle, described housing has multiple side opening, and adopt 25CrNiMo low-carbon alloy steel Double-casing material-structure, described housing forges through Tempering and Quenching mode and forms, hull outside is cast with the reinforcing rib of weight reduction, is coated with one deck anticorrosive paint in enclosure interior.Further, the heavy 4200kg of described housing.
Further, the pressure limit that can bear of described housing is at 110MPa ~ 135MPa.
The invention has the beneficial effects as follows: a kind of preventer housing of the present invention, 25CrNiMo low-carbon alloy steel is adopted to have higher yield strength, tensile strength and fatigue strength, also has enough plasticity and toughness, side opening on housing can throttling pressure release, security performance is high, smear at surface of shell the application life that anticorrosive paint improves preventer well, integration capability is high, has very high economic benefit.
Detailed description of the invention
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 preventer housing, it is characterized in that, described preventer housing is a kind of preventer housing of super-pressure, the pressure limit that described housing can bear is at 110MPa ~ 135MPa, shape is rectangle, described housing there is multiple side opening, described housing forges through Tempering and Quenching mode and forms, adopt 25CrNiMo low-carbon alloy steel Double-casing material-structure, described 25CrNiMo low-carbon alloy steel has high strength, good plasticity and weldability, anticorrosion effect is desirable, case weight is 4200kg, hull outside is cast with the reinforcing rib of weight reduction, one deck anticorrosive paint is coated with in described enclosure interior.
Preventer housing of the present invention, 25CrNiMo low-carbon alloy steel is adopted to have higher yield strength, tensile strength and fatigue strength, also has enough plasticity and toughness, side opening on housing can throttling pressure release, security performance is high, smear at surface of shell the application life that anticorrosive paint improves preventer well, integration capability is high, has very high economic benefit.
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.
