Abstract
An oil well casing gas washing tank comprises a tank body, as well as a gas inlet pipe and a gas outlet pipe which are connected with the tank body, wherein a spraying pipe is arranged at the bottom of the tank body, and communicated with the gas inlet pipe; a plurality of gas outlet holes are formed in the bottom of the spraying pipe; a baffle is arranged below the spraying pipe; separating umbrellas are mounted in the middle of the tank body; each separating umbrella is an umbrella-shaped thin plate with narrow slits; a spray catcher is mounted above the separating umbrellas; a silica-gel drier is paved above the spray catcher; the gas outlet pipe is connected onto the tank body above the silica-gel drier. Through the adoption of the oil well casing gas washing tank, C3, C4, light hydrocarbon, raw oil, water, solid particles and other impurities can be removed in casing gas; purified natural gas can serve as fuel which can be directly used by a natural gas power generator; the oil well casing gas washing tank is simple in structure, small in size, low in cost, convenient to mount and maintain, and particularly applicable to scattered and sporadic oil wells as well as trial-produce oil wells.
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
At present, utilize well casing gas to generate electricity and drive oil recovery unit in well site to be one of major measure of well casing gas recycling.Natural gas generator is to C in Sweet natural gas
3, C
4, liquid ingredients, the component such as solid impurity have strict demand.For making well casing gas reach the specification of quality of natural gas generator to Sweet natural gas component, casing gas generator need be equipped with casing gas refining plant.Existing casing gas refining plant is made up of separator, moisture eliminator and filtration unit.Casing gas isolates oil droplet in separator, then enters moisture eliminator dehydration, finally by the solid impurity in filtration unit filtering Sweet natural gas.Although this casing gas refining plant effectively can purify casing gas, because its volume is large, cost is high, therefore cannot use at the small oil field of dispersion and pilot production oil field.In China, the fragmentary oil well of dispersion and casing gas many employings emptying process of pilot production well, cause the huge wasting of resources and environmental pollution.
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, this well casing gas washing tank adopts skid structure, can not only casing gas be purified, make it reach the specification of quality of natural gas generator to Sweet natural gas, and structure be simple, volume is little, cost is low, maneuverability, easy to maintenance.
The technical solution adopted for the present invention to solve the technical problems is: well casing gas washing tank, comprises tank body, and 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, traverse baffle, separation umbrella, spray catcher and 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, has some production wells bottom spray line.Just to the position of spray line on the downside of spray line, traverse baffle is installed.Be provided with separation umbrella in the middle part of tank body, being separated umbrella is multilayer umbrella thin plate.Be separated on the upside of umbrella and Stainless Steel Cloth 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, is convenient to change 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 bottom even has production well.
The structure of described traverse baffle comprises the annular metal sheet of arranged concentric, and metal sheet is positioned at immediately below spray line ring pipe.
The structure of described separation umbrella comprises some layers of umbrella thin plate, and thin plate radially evenly has some narrow slits, adjacent two narrow slit staggered arrangement.When installing thin plate, the narrow slit staggered arrangement on adjacent two thin plates, is being separated the gas passage forming complications in umbrella.
Well casing gas washing tank working process is:
After well casing gas enters tank body from inlet pipe, evenly spray in tank diesel oil from the production well of spray line bottom, after gas collisions traverse baffle, upwards flow.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.Upwards enter separation umbrella through the washed Sweet natural gas of diesel oil, Tortuous flow in the narrowed flow path in separation umbrella, clash into sheet panel top face, the larger diameter drop carried secretly in Sweet natural gas condenses in plate face, and flows in diesel oil at the bottom of tank.Sweet natural gas after being separated the preliminary demist of umbrella upwards flows into spray catcher, and spray catcher is Stainless Steel Cloth, the small diameter drops collision silk screen carried secretly in Sweet natural gas, and condenses in silk screen surface.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. spray line bottom opening, the air-flow of ejection is after traverse baffle collision crashing, and reflection enters diesel oil washings, thus considerably increases oil, gas contact area, has increased substantially the effect of diesel oil washing, purification casing gas.
2. being provided with separation umbrella in the middle part of tank body, for removing the larger particles drop carried secretly in Sweet natural gas, carrying out preliminary demist process to Sweet natural gas, compensate for the gas that spray catcher can not process with a large amount of drop, this is not enough.
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.
