Utility model content
The purpose of this utility model: a kind of down-hole self-operated type ejector water pumping gas production new tool is provided, utilize energy and the injector nozzle reducing pressure by regulating flow of down-hole natural gas self, make natural gas flow form differential pressure district at mixing chamber, the hydrops in pumping pit shaft, realizes the object of gas stringer water pumping gas production.
The technical solution adopted in the utility model: down-hole self-operated type ejector drainage gas production tool, primarily of urceolus, nozzle support pipe, nozzle, nozzle bearing, larynx mouth apart from pipe, trunnion, anemostat, top connection, flexible pipe composition.
Critical piece is all adopt alloy steel to process, nozzle is seated in nozzle bearing, nozzle support pipe, nozzle bearing, larynx mouth are positioned in urceolus sequentially apart from pipe, trunnion and anemostat, flexible pipe by screwed connection in urceolus lower end, urceolus upper end and top connection are by screwed connection, and top connection and setting hanger pass through screwed connection.
In the method implementation process, first ejector and setting hanger are passed through screwed connection, then utilize steel wire operation to transfer to planned well deep location, realize setting and sealing of ejector by setting hanger.
Down-hole natural gas flow is because of the sealing of upper end hanger, nozzle is entered through ejector urceolus entrance, form low-voltage high speed jet, a low-pressure area is formed at the mixing chamber of larynx mouth in pipe, thus form Negative Pressure Difference district between the flexible pipe be connected with same mixing chamber, suck and carry hydrops, two bursts of gas-liquid flow with different momentum are after entering and carrying out mixing and Momentum Transfer in trunnion, reach mixing and power conversion fully after flowing to anemostat, finally form the synchronized gas-liquid mixed stream with certain pressure energy and discharge well head together.
A kind of down-hole self-operated type ejector drainage gas production tool, urceolus, urceolus is formed with air inlet; Nozzle bearing, is arranged in urceolus, nozzle bearing is formed and draws liquid mouth; Nozzle, is arranged in nozzle bearing, and the air inlet port of nozzle is connected with the air inlet be formed on urceolus, the gas outlet of nozzle, and the gas outlet of nozzle tilts towards the direction of drawing liquid mouth.
Further, also comprise larynx mouth apart from pipe, with nozzle bearing being axially arranged side by side at urceolus, nozzle and draw liquid mouth all with larynx mouth distance pipe be connected.
Further, also comprise anemostat, anemostat is connected apart from pipe with larynx mouth, and the internal diameter of anemostat increases along away from larynx mouth gradually apart from pipe direction.
Further, it is characterized in that, also comprise trunnion, nozzle bearing, larynx mouth are successively set in urceolus apart from pipe, trunnion and anemostat, and larynx mouth is communicated with apart from pipe, trunnion successively with anemostat.
Further, also comprise top connection, be connected to one end of the close anemostat of urceolus, top connection is for connecting setting hanger.
Further, above-mentioned down-hole self-operated type ejector drainage gas production tool, also comprises flexible pipe, and draws liquid mouth and is connected.
Further, also comprise nozzle support pipe, flexible pipe with draw liquid mouth and be connected by nozzle support pipe.
The beneficial effects of the utility model: the utility model spray application technique, make full use of energy and the injector nozzle reducing pressure by regulating flow of down-hole natural gas self, make natural gas flow form differential pressure district at mixing chamber, the hydrops in pumping pit shaft.By wire rope operation, instrument is delivered to design attitude, increases lifting rate, reduce hydrops, effective control pit shaft inner product level, compares the strong water-pumping/draining gas production operation of tradition, without the need to extra power, greatly reduces operating cost.
Because ejector can be engaging in any well depth position by setting hanger, therefore, according to the gas well plug-ging degree of depth and gas well Production design determination ejector depth of setting, meanwhile, the degree of depth that hose length effectively can control pit shaft inner product liquid level can be made full use of.
