Abstract
The utility model discloses a three well-head used for mouths of anti-leak and decompression oil wells, comprising a shell and an oil inlet nozzle, an oil outlet nozzle and a sealed nozzle which are arranged on the shell, a packing base is installed inside the sealed nozzle, the oil inlet nozzle is arranged at the lower end of the shell, the outside diameter of the shell is larger than that of the oil inlet nozzle, the oil outlet nozzle and the sealed nozzle are respectively arranged at one side and the top part of the shell. The inner cavity of the shell is a decompression chamber, which is respectively connected with the oil inlet nozzle, the oil outlet nozzle and the sealed nozzle, a decompression value is arranged at the upper part of the decompression chamber and a filter is arranged at the lower part; a valve plug is installed under the a packing base. The design of the utility model is reasonable and simple. By reducing the oil pressure, not only the leakage of crude oil is thoroughly resolved and the oil field environment is well protected, but also the sealing material such as rubber is saved by 95 percent and 4000 to 5000 yuan can be saved by each well every year.
Description
Technical field
The utility model relates to a kind of oil field shaft mouth oil recovery parts, is specifically related to a kind of anti-well mouth of oil well threeway of letting out, reduce pressure.
Background technology
At present, the threeway that oil field shaft mouth uses is the straight tubular that diameter does not change, relief capabilities to former oil pressure is poor, not only need to consume a large amount of encapsulants such as packing aborning, strengthened cost of production, and, cause severe contamination to environment because the problem that pressure causes crude oil to leak can not get solving.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, and a kind of reasonable in design, simple in structure, the anti-well mouth of oil well threeway of letting out, reduce pressure that can effectively alleviate former oil pressure, reduce production costs is provided.
For achieving the above object, the technical solution adopted in the utility model is: a kind of anti-well mouth of oil well threeway of letting out, reduce pressure, comprise housing and be arranged on the oil-feed mouth of pipe on the housing, the fuel-displaced mouth of pipe and sealing orifice, be positioned at sealing orifice and be provided with the packing base, it is characterized in that: the described oil-feed mouth of pipe is arranged on the bottom of housing, the external diameter of housing is greater than the external diameter of the oil-feed mouth of pipe, and the described fuel-displaced mouth of pipe and sealing orifice are separately positioned on a side and the top of housing; The inner chamber of housing is the pressure-reducing chamber, and the oil-feed mouth of pipe, the fuel-displaced mouth of pipe and sealing orifice are communicated with the pressure-reducing chamber respectively; The top in pressure-reducing chamber is provided with reducing valve, and its underpart is provided with strainer; The below of packing base is provided with valve plug.
The utility model compared with prior art has the following advantages: the utility model is reasonable in design; simple in structure; owing to reduced the pressure of crude oil; not only thoroughly having solved crude oil leaks; protected the oil field environment; but also can save 95% encapsulants such as rubber, the annual individual well of only this item can be saved 4000～5000 yuan.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
A kind of anti-well mouth of oil well threeway of letting out, reduce pressure as shown in Figure 1, comprise housing 6 and the oil-feed mouth of pipe 1, the fuel-displaced mouth of pipe 2 and the sealing orifice 3 that are arranged on the housing 6, be positioned at sealing orifice 3 and be provided with packing base 5, the described oil-feed mouth of pipe 1 is arranged on the bottom of housing 6, the external diameter of housing 6 is greater than the external diameter of the oil-feed mouth of pipe 1, and the described fuel-displaced mouth of pipe 2 and sealing orifice 3 are separately positioned on a side and the top of housing 6; The inner chamber of housing 6 is pressure-reducing chamber 7, and the oil-feed mouth of pipe 1, the fuel-displaced mouth of pipe 2 and sealing orifice 3 are communicated with pressure-reducing chamber 7 respectively; The top in pressure-reducing chamber 7 is provided with reducing valve 9, and its underpart is provided with strainer 10; The below of packing base 5 is provided with valve plug 8.
The external diameter of described housing 6 is 10～14cm.
During the utility model work, because the diameter of housing 6 increases suddenly, therefore the pressure that enters the crude oil in the pressure-reducing chamber 7 is eased rapidly, pressure reduces, and the depressurization of reducing valve 9 significantly reduces the pressure that acts on valve plug 8 and the packing in addition, thereby improved the working condition of packing, prolong application life, reduced the loss of packing, prevented leaking of crude oil.
