Abstract

A blowout drainage device for a natural gas well comprises a base plate (1), a gas inlet pipe (2), an escape pipe (7), a drainage pipe (9) and the like. The blowout drainage device is characterized in that a pressure reducing component (3) is correspondingly mounted at a pressure reducing valve (5) in a tank (8), and a pressure reducer (4) is mounted in a shell of the tank (8). The blowout drainage device is reasonable in structural design and easy to operate, is used for blowout drainage of the natural gas well, and can directly use stratum energy, so that the process is simple, construction efficiency is high, and any pollution to a stratum is avoided.

Description

Natural gas well open flow dewatering installation
Technical field: the utility model relates to a kind of oil field mining site equipment, especially for a kind of natural gas well open flow dewatering installation of natural gas extraction.
Background technology: before the utility model, each oil field natural gas well adopts pumping, gaslift or chemical method to carry out draining more, not only complex process, long construction period, but also possibly cause formation contaminant.
Summary of the invention: the purpose of the utility model is: for the oil field gas production provides a kind of natural gas well open flow dewatering installation; Because this device is through the direct open flow draining of the pressure relief assembly control natural gas well; Therefore not only technology is simple, efficiency of construction is high, but also can not cause any pollution to the stratum.
The purpose of the utility model realizes through following measure: a kind of natural gas well open flow dewatering installation; Comprise chassis, air inlet pipe, reducing valve, constant pressure valve, blow-down pipe, tank body, gutter, manhole; And above having the tank body on chassis reducing valve, constant pressure valve, blow-down pipe are installed; Its side is equipped with manhole, the bottom is equipped with gutter, and reducing valve, constant pressure valve also are connected with air inlet pipe simultaneously, it is characterized in that reducing valve place in tank body; Correspondence is equipped with pressure relief assembly, and the bowl-shape pressure reducer of porous is installed in the shell of the bowl-shape pressure relief assembly of lower openings.
The purpose of the utility model can also realize through following measure: the pressure relief assembly that install at the reducing valve place in the tank body can be the 2-4 level, and each inter-stage is connected through screw thread.
The utility model reasonable in design, easy operating is used for natural gas well open flow draining, can directly utilize stratum energy, and therefore not only technology is simple, efficiency of construction is high, but also can not cause any pollution to the stratum.
Description of drawings: Fig. 1 is the structural representation of natural gas well open flow dewatering installation.
The specific embodiment: natural gas well open flow dewatering installation is by chassis 1, air inlet pipe 2, pressure relief assembly 3, pressure reducer 4, reducing valve 5, constant pressure valve 6, blow-down pipe 7, tank body 8, gutter 9, manhole 10; And above having the tank body 8 on chassis 1 reducing valve 5, constant pressure valve 6, blow-down pipe 7 are installed; Its side is equipped with manhole 10, the bottom is equipped with gutter 9, advances reducing valve 5, constant pressure valve 6 simultaneously and also is connected with tracheae 2; Reducing valve 5 places in tank body 8, correspondence is equipped with pressure relief assembly 3, and the bowl-shape pressure reducer 4 of porous is installed in the shell of the pressure relief assembly 3 that lower openings is bowl-shape; The pressure relief assembly of installing in the tank body 83 can be the 2-4 level, and each inter-stage is connected through screw thread.
The operating principle and the method for using of natural gas well open flow dewatering installation are: the pressure relief assembly 3 that at first should select to install the 2-4 level according to the natural gas well energy of treating operation; And close all valves on this device; Through air inlet pipe 2 this device is connected with its well head again, just can carries out the open flow draining; Open well head and reducing valve 5 during operation earlier; This moment, the gas of down-hole just got in the tank body 8 through air inlet pipe 2, reducing valve 5, pressure relief assembly 3; Pass through the gas-water separation of tank body 8 again; Gas is then discharged through blow-down pipe 7, and the liquid after the separation then can be discharged through gutter 9, thereby has accomplished the decompression open flow draining of the natural gas well; After operation construction a period of time, visual natural gas well energy decreases situation is closed reducing valve 5, is opened constant pressure valve 6, carries out the without hindrance open flow draining of the natural gas well, until last realization operative goals.Because this device only consumes the self-energy of the natural gas well in operation, and have no pumping equipment to participate in, therefore not only technology is simple, efficiency of construction is high, but also can not cause any pollution to the stratum.
