Description
Technical field
The present invention relates to oil gas production equipment technical field, be specifically related to a kind of low-pressure gas well multiple filtration gas-liquid and divide
From method.
Background technology
In the recovery process in oil field, there is subnormal pressure in part oil field, brings certain difficulty to well workover, and part gas well is low
Press off and adopt, shake out and bury stratum and cannot clear up in time so that the reduction of gas well yield even stops production.There is no external energy
Implementing underground work under supplementary information, workover fluid is increasingly severe to the pollution on stratum so that after effect, the discharge opeing cycle constantly prolongs
Long.Therefore, no matter it is to be required to carry out pressurized treatment to such gas well when exploitation or discharge opeing.In prior art, it will usually
With supercharging unit to gas well supercharging, and the natural gas extracted out often can carry the liquid of part together by conveyer belt pipeline, for this
With gas well, gas-liquid separator can be installed at supercharging unit.In actual use, the separation efficiency of gas-liquid mixture is that it is main
Mostly problem to be solved, for solving this problem, be that this makes structure of gas liquid separator multiple by arranging what the filter element of complexity realized
Miscellaneous, cost of manufacture is higher.Additionally, in gas-liquid mixture, there is also some solid impurities, the solid impurity of excess can make discharge opeing
Blockage, thus affect the use of gas-liquid separation device.
Summary of the invention
The purpose of the present invention is i.e. to overcome the deficiencies in the prior art, it is provided that a kind of low-pressure gas well multiple filtration gas-liquid is divided
From method, by the filter element separating liquid/gas mixtures that cross section is T-shaped, the connecting portion of filter element, filter cylinder and filter form three grades of mistakes
Filter, makes gas-liquid separation efficiency of the present invention high, and the present invention is further through consolidating in the collection strainer filtering gas-liquid mixture below filter element
Body impurity, to prevent discharging tube from blocking.
The goal of the invention of the present invention is achieved through the following technical solutions:
Low-pressure gas well multiple filtration gas-liquid separating method, it is characterised in that include step:
Step 1) upper end at cylinder is provided with upper end cover, the lower end of cylinder is provided with bottom end cover, gas-liquid mixed
Thing is provided with air inlet pipe near the barrel of upper end from cylinder and enters separator;
Step 2) in cylinder, it is provided with the filter element that cross section is T-shaped, after gas filtration, by going out of arranging on upper end cover
Trachea is discharged;Described filter element includes horizontally disposed connecting portion, vertically disposed filter cylinder and several mistakes being arranged in filter cylinder
Filter disc, described connecting portion connector drum inwall and the upper surface of filter cylinder;
Step 3) it is provided with bottom filter element in cylinder and points to, along tubular axis, the collection filter that the direction of bottom end cover bends
Net, is provided with corrugated screens in the upper end of described collection filter screen, and liquid is through corrugated screens and collects strainer filtering;
Step 4) by be provided with at bottom end cover bottom surface nadir discharging tube will separate after liquid discharge.
In oil exploitation, the gas-liquid mixture of extraction is entered in cylinder by air inlet pipe, swiftly flowing gas-liquid mixed
Thing collides with filter element, and gas-liquid mixture during motion, has small part of gas through connecting portion in the space that filter element and cylinder are formed
Directly arrive cylinder upper end, more gas and the multiple filtration sheet collision in filter cylinder and filter cylinder, such three-stage filtration, it is possible to make
Liquid component in gas-liquid mixture is maximized to be settled by filtration, and gas part is by finally moving to cylinder upper end after filter element
Dynamic, and discharged by the escape pipe on upper end cover, and liquid portion deposits to cylinder lower end, is finally discharged by discharging tube.Multistage mistake
Filter improves the strainability of the present invention, and its simple in construction, low cost of manufacture.
The solid impurity of minority is there will be in gas-liquid mixture, and in the first mistake of gas-liquid mixture experience filter element sidewall
The bottom to filter element is moved, owing to the size of solid impurity is bigger, it is impossible to directly by filter element, be therefore separated after filter
Solid impurity is directly lost in corrugated screens.Corrugated screens, refers to that its outer surface is wavy drainage screen, and its surface area is remote
More than the flat screen of comparable size, the upper surface that can be prevented effectively from it is blocked and causes liquid to decline and has some setbacks;Due to cylinder
The gas that middle and upper part is divided continues through, and the air pressure that therefore cylinder middle and upper part is divided is less than the air pressure of cylinder body bottom, and is positioned at cylinder
The liquid of bottom can occur springing up because two-way pressure is uneven, and downward projection of collection filter screen is then mainly used in calming down cylinder
The liquid of the accumulation of bottom, and then ensure the even running of cylinder.
Further, described step 3) in, the filter opening aperture of described corrugated screens is more than the filter opening hole of described collection filter screen
Footpath so that the solid impurity in corrugated screens can fall to collect on filter screen smoothly, it is to avoid the impurity in corrugated screens is too much
And affect the gas flowing of cylinder body bottom and reduce the bearing capacity in corrugated screens, prevent it impaired.
Further, described step 3) in, described collection filter screen and corrugated screens all removably connect with cylinder inboard wall, just
In periodic cleaning cylinder.
Further, described step 1) in, described upper end cover and bottom end cover are connected with cylinder screw, upper end cover and bottom end cover
To scribble fluid sealant, upper end cover and bottom end cover threaded with cylinder junction, it is simple to the present invention overhauls, and fluid sealant is for ensureing this
The air-tightness of invention.
Further, described step 1) in, described air inlet pipe is tightly connected with cylinder, and described escape pipe seals with upper end cover
Connecting, described discharging tube is tightly connected with bottom end cover.
The present invention compared with prior art, has such advantages as and beneficial effect:
The present invention forms three-stage filtration by the connecting portion of filter element, filter cylinder and multiple filter, it is possible to make gas-liquid mixture
In liquid component maximized settled by filtration, improve the strainability of the present invention, and its simple in construction, manufacturing cost
Low.It addition, the present invention is by collecting the solid impurity in filter screen and corrugated screens double medium filtration gas-liquid mixture, in case discharging tube
Blocking, affect the present invention and normally uses, and collects the corrugated screens on filter screen and is prevented effectively from again it and blocks and affect gas-liquid and mix up thing
Flowing.
