Description
Technical field
The utility model relates to oil extraction in oil field technical field, especially relates to a kind of well head medicine-adding and anaerobic tail gas airlift unit.
Background technology
When the energy shortage of stratum supply is to give rise to ground crude oil from shaft bottom, oil well just goes dead, fuel-displaced in order to make oil well continue, and needs artificially gas (air) to be pressed into shaft bottom, make crude oil spray ground, this oil production method is called gas-lift production.And during the oil extraction of, physical property difference great disparity complicated at geological condition, need to add in well wellbore and in Produced Liquid plurality of liquid medicament, comprise demulsifier, thinner, cured clearly dose, corrosion inhibiter etc.The kind of the liquid preparation added and quantity, require to determine according to the character of Produced Liquid and processing procedure.
At present, there is many disadvantages in the medicine machine of original airlift unit and chemicals dosing plant, chemicals dosing plant is lack of standardization and be separated with airlift unit, each oil recovery factory, each ore deposit medicine machine and airlift unit are multifarious, cannot unified management, and cause the production efficiency of oil extraction low, and cost, costly.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of well head medicine-adding and anaerobic tail gas airlift unit, improves production efficiency, reduce cost of production.
The utility model provides a kind of well head medicine-adding and anaerobic tail gas airlift unit, comprises skid platform, wellhead chemicals-feeder, the generation of tail tail gas and gathering-device, the first ball-and-seat, the second ball-and-seat, closes and note valve and outlet; Described wellhead chemicals-feeder and tail gas produce and are fixedly installed on described skid platform respectively with gathering-device; Described wellhead chemicals-feeder connects described first ball-and-seat, described exhaust collection airlift unit connects described second ball-and-seat, described first ball-and-seat and the second ball-and-seat are communicated with described the same side of noting valve of closing respectively, and described outlet connects the described opposite side closing note valve.
Further, described wellhead chemicals-feeder comprises chemical tank and medicating mechanism, and described chemical tank is connected with described medicating mechanism.
Further, described tail gas produces and comprises diesel engine and tail gas collecting device with gathering-device, and described diesel engine is provided with the offgas outlet be connected with described tail gas collecting device, and described tail gas collecting device is connected with described second ball-and-seat.
Further, the corner of described skid platform is provided with and is convenient to it and fixes or the suspension hook of movement.
The beneficial effects of the utility model are: adopt well head medicine-adding of the present utility model and anaerobic tail gas airlift unit, tail gas generation produces with gathering-device carries out collection anaerobic tail gas, medicament and the tail gas of wellhead chemicals-feeder produce to be noted valve place and collects and mix respectively by after the first ball-and-seat, the second ball-and-seat closing with the anaerobic tail gas of gathering-device, and mixed band medicament gas through outlet pipe is delivered to oil country tubular good.First ball-and-seat, the second ball-and-seat all adopt one-way flow to design, and can prevent the backflow of the anaerobic tail gas with medicament.Simply, easy to use, cost of production is low for well head medicine-adding of the present utility model and anaerobic tail gas airlift unit structure.
Accompanying drawing explanation
