Abstract
The utility model discloses a shock-absorbing wear-resistant joint of an oil well fracturing pipeline, which relates to oil layer fracturing pipe equipment in the field of oil field exploitation, and comprises a shell, a reducer union, a packing, a first sleeve and a second sleeve, wherein the reducer union is installed at the top of the shell; the bottom internal thread screw of casing has the second sleeve pipe, and the second sleeve pipe is arranged in to the lower extreme of first sleeve pipe, is equipped with the packing in the casing between the lower terminal surface of second sleeve pipe up end and reducing joint. According to the device, the packing and the movable reducing joint are arranged in the shell, so that when the first sleeve works, the hydraulic pressure of fluid in the first sleeve is higher, and the sealing force of the reducing joint in the shell is higher; meanwhile, the packing is used as an elastic sealing element, so that vibration in any direction of space can be absorbed, and a good vibration isolation effect is achieved; the setting of wearing layer can prolong first sheathed tube life, improves production efficiency.
Description
Technical Field
The utility model relates to an oil field exploitation field oil reservoir fracturing pipe equipment, concretely relates to oil well fracturing pipeline shock attenuation wear-resisting joint.
Background
In the oilfield industry, fracturing stimulation of oil and gas fields is typically accomplished using fracturing tubulars connected by fracturing joints. However, the pipe joints have single function, only can play a role in simple connection, and have poor sealing effect, and when the existing high-pressure discharge manifold is subjected to long-time fracturing operation, the fluid in the existing high-pressure discharge manifold has large impact on an oil pipe, the whole fracturing high-pressure manifold system often has abnormal vibration under the impact of the fluid pressure, and the abnormal vibration can cause the problems that a structural mutation part and a stress concentration part are easy to generate fatigue cracks, the flange connection fails, the pipe wall is punctured and burst, and the like; meanwhile, the inner wall of the existing fracturing pipe joint is not wear-resistant, and the service life of the joint is shortened due to long-time fluid impact, so that the production efficiency is influenced. Therefore, a shock absorbing wear resistant joint for an oil well fracturing pipeline is needed to solve the above problems.
Disclosure of Invention
Not enough to prior art, the utility model provides an oil well fracturing pipeline shock attenuation wear-resisting joint.
The utility model discloses a shock-absorbing wear-resistant joint for an oil well fracturing pipeline, which comprises a shell, a reducer union, a packing, a first sleeve and a second sleeve, wherein the reducer union is installed at the top of the shell; the bottom internal thread screw of casing has the second sleeve pipe, and the second sleeve pipe is arranged in to the lower extreme of first sleeve pipe, is equipped with the packing in the casing between second sleeve pipe up end and the lower terminal surface of reducing joint.
As a further improvement of the utility model, a rubber sealing ring is arranged between the shell and the reducer union.
The shock-absorbing wear-resistant joint for the oil well fracturing pipeline has a compact and reasonable structure, and the packing and the movable reducer union are arranged in the shell, so that the hydraulic pressure of the fluid in the first sleeve is higher when the first sleeve works, the sealing force of the reducer union in the shell is higher, and the sealing effect is better; meanwhile, the packing is used as an elastic sealing element, so that vibration in any direction of space can be absorbed, and a good vibration isolation effect is achieved; the setting of wearing layer can prolong first sheathed tube life, improves production efficiency.
