Description
Technical field
The invention belongs to well casing gas purification technology field, be specifically related to a kind of well casing gas washing tank.
Background technology
Well casing gas is associated gas, is a kind of mixed gas being rich in the low molecule alkane such as methane.In crude production, the recycling mode of casing gas mainly contains: casing gas is injected crude oil pipeline and recycle; Directly as well site boiler oil; Natural gas generator is utilized to generate electricity.Wherein, utilize casing gas to generate electricity and drive oil recovery unit in well site to be one of major measure of well casing gas recycling.Because natural gas generator is to the C in Sweet natural gas
3, C
4, liquid ingredients, the component such as solid impurity have strict demand, therefore, casing gas generator is all equipped with casing gas refining plant.Existing casing gas refining plant primarily of separator, moisture eliminator and filtration unit three part composition.Oil droplet is separated by casing gas first in the separator, enters moisture eliminator drying and dehydrating, finally by filtration unit filtering solid impurity, becomes qualified natural gas generator fuel gas.Because existing casing gas refining plant volume is large, cost is high, therefore cannot use at the small oil field of dispersion and pilot production oil field.In China, the small oil field of many fragmentary dispersions and the casing gas in pilot production oil field still adopt ignite the torch, the mode process such as emptying, cause the huge wasting of resources and environmental pollution.
Containing C in casing gas
3, C
4deng heavy hydrocarbon composition, the existence of these components can affect performance and the work-ing life of natural gas power unit.At present, C in Sweet natural gas is removed
3, C
4method Deng component mainly contains separation by deep refrigeration, absorption method etc.The heavy hydrocarbon composition in Sweet natural gas although these methods can effectively be escaped danger, because its complex process, cost are high, therefore cannot use in the well site in the small oil field of dispersion and pilot production oil field.
Summary of the invention
In order to overcome the deficiency that existing casing gas refining plant volume is large, cost is high, the invention provides a kind of well casing gas washing tank with collision sieve plate, this well casing gas washing tank effectively can remove the C in casing gas
3, C
4deng heavy hydrocarbon composition, be therefore specially adapted to be rich in C in associated gas
3, C
4in the oil field of heavy hydrocarbon composition.This casing gas washing tank adopts skid structure, and structure is simple, and volume is little, and cost is low, and maneuverability is easy to maintenance.
The technical solution adopted for the present invention to solve the technical problems is: a kind of well casing gas washing tank with collision sieve plate, comprise tank body, tank base has diesel oil pipe, and tank body lower part is connected with inlet pipe, and tank body top is connected with escape pipe, and hand hole is arranged at tank body top.Spray line, baffle plate, collision sieve plate, spray catcher, siccative is had in tank body.It is characterized in that: tank base is provided with spray line, spray line is communicated with inlet pipe, and spray line top has some production wells.On the downside of spray line, baffle plate is installed.Be provided with some layers of collision sieve plate on the upside of spray line, collision sieve plate is the metal sheet having some holes, and the hole on adjacent sieve plate is staggered.On the upside of collision sieve plate, spray catcher is installed.Silica-gel drier is provided with on the upside of spray catcher.On the upside of siccative, tank body upper position is provided with escape pipe.Tank body top is provided with hand hole, is convenient to change siccative.Tank base is provided with diesel oil pipe, for changing diesel oil in tank.
The structure of described spray line comprises the ring pipe of some arranged concentric, and each ring pipe is interconnected, and is communicated with inlet pipe, and ring pipe top evenly has some production wells.
The structure of described baffle plate comprises several metal sheets, and metal sheet is shutter shape arrangement.And be welded on tank body lower part position.
The structure of described collision sieve plate comprises some layers and opens pertusate metal sheet, each metal sheet equidistantly arranges, the hole that one deck collision sieve plate of next-door neighbour's spray line is opened and spray line top production well are staggered, on adjacent collision sieve plate, institute's hole-opening is staggered, under collision sieve plate is positioned at the diesel oil liquid level of tank base.
Described spray catcher is waved plate spray catcher.
A kind of working process of the well casing gas washing tank with collision sieve plate is:
After well casing gas enters tank body from inlet pipe, evenly to spray in tank diesel oil from the production well at spray line top, air-flow is impact flow collision sieve plate plate face upwards, heavier drop and solid impurity fall into bottom washing tank along the gap between baffle plate downwards, and the hole on lighter gas self collision sieve plate is upwards overflowed.Gas upwards flows in diesel oil, often through one deck collision sieve plate, all wants impact sieve plate plate face.Through the washing of diesel oil, the crude oil in casing gas, light oil, C
3, C
4etc. components dissolved in diesel oil, meanwhile, the water in casing gas and solid impurity is eliminated.Waved plate spray catcher is upwards flowed into through the washed Sweet natural gas of diesel oil.During the runner of the Sweet natural gas carrying mist of oil secretly by waved plate spray catcher complications, oil droplet is crash panel face under mass force effect, at waved plate surface aggregation, finally to flow in tank in diesel oil.Sweet natural gas after spray catcher demist upwards flows into siccative, dewaters further, after drying, discharges from the escape pipe on tank body top through siccative.
The invention has the beneficial effects as follows and be:
1. be provided with some layers of collision sieve plate on the upside of spray line, casing gas sprays in tank in diesel oil by spray line, and air-flow is repeated impact sieve plate in uphill process, considerably increases oil, gas contact area, thus increases substantially C in casing gas
3, C
4deng the removal efficiency of composition.Meanwhile, air-flow repeated impact sieve plate is conducive to drop heavier in gas and the separation of solid impurity.
2. be provided with shutter shape baffle plate on the downside of spray line, the reflected gas stream disturbance formed after can preventing gas shock from colliding sieve plate is deposited on the impurity at the bottom of tank.
3. well casing gas washing tank have that structure is simple, volume is little, easy for installation, run in few without the need to human attendance, maintenance workload, manufacture and the feature such as running cost is low, be therefore specially adapted to oil well and the pilot production oil well of fragmentary dispersion.
