Description
Technical field
The utility model is the underground equipment of oilfield production usefulness, particularly a kind of pumpingh well gas anchor.
Background technology
In oil well, the well air content that has is large, and when pumping with oil well pump, the gas-liquid ratio that enters in the oil well pump is large, reduces well liquid discharge capacity, and oil well output is low, and pump efficiency is low, and after air content surpassed certain value, oil well pump also gas lock can occur, and causes oil well not fuel-displaced.In order to reduce gas to the impact of oil well pump work, the oil field is often adopted to install under pump and is utilized the gas anchor of slippage effect and Gravity Separation simply to separate, and prevents that gas from entering in the pump, although this gas anchor has certain effect, but for the large oil well weak effect of air content, can not sand block, sub-sand.The multistage separating gas anchor is adopted at the scene sometimes, although certain liquid gas separating effect is arranged, complex structure, cost of production is high, can not sand block, sub-sand, can't resolve sand to the impact of oil pumping.
Summary of the invention
The purpose of this utility model provides a kind of pumpingh well gas anchor, is installed under the oil well pump in the pumpingh well, and gas-liquid sand is separated, and reduces the gas that enters oil well pump, improves the pump efficiency of oil well pump, improves the oil well economic benefit.
The purpose of this utility model is achieved in that and comprises top connection, tap, flowline, urceolus, lower contact, the exhaust valve ball, mix feed tube, the urceolus upper side has and outreaches groove, the tap side has inline groove, tap is fixed in the urceolus top, inline groove is aimed at and is outreached groove, urceolus top is connected with the top connection bottom, top connection is hollow structure, internal thread is arranged at top connection top, fuel-displaced eccentric orfice is arranged in the tap, the exhaust eccentric orfice, exhaust eccentric orfice and inline groove, outreaching groove communicates, lay the exhaust valve ball in the exhaust eccentric orfice, the exhaust valve ball makes the exhaust eccentric orfice, inline groove, outreach unidirectional the communicating of passage that groove forms, the flowline upper end is installed in the fuel-displaced eccentric orfice of tap, and be fixed into one with tap, flowline communicates with top connection inside by fuel-displaced eccentric orfice, flowline is in the urceolus, mixing the feed tube bottom is installed in the eccentric orfice of lower contact, mixing feed tube communicates with the lower contact bottom, mixing feed tube inserts in the urceolus, lower contact top is connected with the urceolus bottom, flowline, mix that feed tube is parallel to be in the urceolus, make and form flow channels in the urceolus, flow channels communicates with the flowline bottom, and flow channels communicates with mixing feed tube top.
The beneficial effects of the utility model are: after liquid vapour mixture is discharged from mixing feed tube upper end, fluid diversion flows downward, during fluid diversion, gas-liquid separation, the gas of separating is opened the exhaust valve ball, through the exhaust eccentric orfice, inline groove, outreach groove and inwardly drain into the oil well cover, liquid flows downward in flow channels, through flowline, fuel-displaced eccentric orfice, top connection is upwards flowed by the oil well pump extraction, gas-liquid mixture had been realized efficient separation before well liquid flow to oil well pump, good separating effect, reduced the gas that enters oil well pump, can improve the pump efficiency of oil well pump, the bottom also can hang downhole tools such as considering sandpipe and realize the functions such as sand control, has significant economic benefit.
