Abstract
A large-diameter oil-gas separating gas anchor comprises an outer pipe, an upper joint, a central pipe, a multistage separation umbrella and a lower joint, and is characterized in that the central pipe adopts an oil pipe with the diameter of 62 mm; the upper joint adopts an oil pipe coupling; the lower joint adopts oil pipe male threads; the outer pipe with the diameter ranging from 108 mm to 114 mm is sleeved at the periphery between the upper joint and the lower joint of the central pipe; the screw-type multistage separation umbrella or umbrella-type multilayer separation umbrella is arranged between the outer pipe and the central pipe; the separation umbrella is fixed on the central pipe; a gap is formed between the separation umbrella and the outer pipe; a plurality of vent holes are uniformly formed at the periphery of the central pipe at the lower part of the separation umbrella; a plurality of vent holes are uniformly formed at the periphery of the outer pipe at the upper part of the separation umbrella; and the upper joint and the lower joint are connected between tail pipes at the lower part of an oil-well pump. The utility model effectively solves the problems of the prior art, such as poor anti-gas effect, easy generation of air locking to the oil-well pump and influence to the pump efficiency, and improves the oil-well production.
Description
One, technical field
The utility model relates to a kind of oil field used big latus rectum Oil-gas Separation gas anchor in oil well gas-tight technology.
Two, background technology
At present, development along with the oil field, all kinds of extraordinary oil reservoirs have obtained exploitation, sand, wax, water, gas, thick, it is the various factors that influences oil well production, wherein high gassiness oil well gas produces gas lock to oil well pump, has influenced the ordinary production of oil well, and becoming the gassiness block influences one of key factor of oil well production.
1, the oil recovery technique of current oil well gas-tight, main following measure, the gas-tight oil well pump of adopting; Put sleeve pipe gas in the manufacturing process; Use is the result show, effect is undesirable, particularly for fouling serious and heavy oil block to contain gas well more undesirable.
2, manufacturing process is used the gas-tight oil well pump, find that by using present technology has the following disadvantages, rising along with well water, the eccentric wear well number of gassiness oil well constantly increases, and the distance and the length of rod and tube partial-wear constantly increase, and the use of gas-tight oil well pump also has been subjected to influence, the gas-tight deleterious, the rise of water cut corrosion and scaling further increases the weight of simultaneously, and air trap makes the gas-tight oil well pump that the gas lock phenomenon take place once more because corrosion and scaling may be malfunctioning.
3, the use of common gas and sand anchor, at present, except that using the gas-tight oil well pump, the oil well gas-tight has also used common gas and sand anchor, the central tube diameter of present common gas and sand anchor is generally between 25mm-35mm, mainly have the following disadvantages in the use, a, perishable fouling, central tube stops up, make oil circuit not smooth, have a strong impact on oil gas separation and oil well liquid-supplying, further influence oil well output, particularly poorer for the heavy oil wells effect; The oil pipe that the general use of the outer tube of b, common gas and sand anchor is 73mm-88.9mm is made outer tube, because the restriction of outer tube is that the separation umbrella is less than normal, has further influenced oil gas separation.
4, put sleeve pipe gas in the manufacturing process, improved the gassiness oil well yield to a certain extent, but seriously caused the waste of natural gas energy resource, pollute again simultaneously.
Three, summary of the invention
The purpose of this utility model provides a kind of big latus rectum Oil-gas Separation gas anchor, solves the problem that above-mentioned prior art exists.
The technical solution of the utility model realizes in the following manner:
Big latus rectum Oil-gas Separation gas anchor, form by outer tube, top connection, central tube, multi-stage separation umbrella and lower contact, it is characterized in that central tube is made as diameter 62mm oil pipe, top connection is tubing coupling, lower contact is the oil pipe male thread, on the central tube between the lower contact periphery be with the outer tube of a diameter between 108-114mm, between outer tube and central tube, be provided with screw type multi-stage separation umbrella or umbrella formula multilayer is separated umbrella, separate umbrella and be fixed on the central tube, separate between umbrella and the outer tube being provided with the gap; Evenly be provided with several air vents being in the central tube periphery of lower part, evenly be provided with several air vents being in the outer tube periphery of top from umbrella from umbrella; Last lower contact is connected between the tail pipe of oil well pump bottom.
The utility model has solved prior art gas-tight weak effect effectively, easily makes oil well pump produce gas lock and influences the problem of pump efficiency, has improved oil well yield.

Five, the specific embodiment:
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model is made up of outer tube 1, top connection 2, central tube 3, multi-stage separation umbrella 4 and lower contact 5, it is characterized in that central tube is made as diameter 62mm oil pipe, top connection is tubing coupling, lower contact is the oil pipe male thread, on the central tube between the lower contact periphery be with the outer tube of a diameter between 108-114mm, between outer tube and central tube, be provided with screw type multi-stage separation umbrella or umbrella formula multilayer is separated umbrella, separate umbrella and be fixed on the central tube, separate between umbrella and the outer tube being provided with the gap; Evenly be provided with several air vents being in the central tube periphery of lower part, evenly be provided with several air vents being in the outer tube periphery of top from umbrella from umbrella; Last lower contact is connected between the tail pipe of oil well pump bottom.
When using the utility model, connect between the tail pipe of oil well pump bottom, formation oil enters in the oil well pump by tail pipe, reduction along with pressure, part natural gas can be separated, form air pocket, when air vent place to central tube, pressure reduces suddenly, natural gas enters the annular space of outer tube and central tube, can bleed off from well head as the casing pressure height, and isolated crude oil is drawn back tail pipe by oil well pump again and entered oil well pump, so just prevented that natural gas from entering the oil pumping pump barrel, influenced pump efficiency or produce gas lock.
