Abstract
The utility model relates to a common matched tool for an oil pumping well, and particularly relates to a gas and sand anchor for an oilfield well. The gas and sand anchor for the oilfield well includes an upper joint, a gas hood, a connecting joint, upper pressure caps, an inner screen pipe, an outer screen pipe, lower pressure caps, a lower joint, and a gas pipe. The upper joint is connected to the lower joint via a connecting joint, the gas pipe is arranged between the upper joint and the connecting joint, the top part of the gas pipe is connected to the gas hood, the inner screen pipe and the outer screen pipe are arranged between the lower joint and the connecting joint, the top parts of the inner screen pipe and the outer screen pipe are the upper pressure caps, and the bottom parts of the inner screen pipe and the outer screen pipe are the lower pressure caps. The gas and sand anchor is advantageous in that the anchor can meet the requirements of high oil-gas ratio, and the gas proofing and the sand proofing of a fine-silty sand oil well, integrates the gas proofing and the sand proofing functions into one body; moreover, the anchor adopts the inner and outer screen pipes to realize high sand proofing effects and high permeability, the anchor adopts a spiral structure to realize good separation effects and high pump efficiency, thereby prolonging the service lifetime of a deep well pump, and improving the production efficiency.
Description
Technical field
The utility model relates to a kind of pumpingh well kit commonly used, and particularly a kind of oil field well is used gas and sand anchor.
Background technology
Oil-gas field development is to the middle and later periods, because stratum energy is not enough, often adopts deep well oil pumping to extract underground crude oil out ground.In this process, because gas gets into deep well pump, influence the deep well pump pump efficiency, the gas lock phenomenon can take place when serious, cause oil well not fuel-displaced; In addition, because oil reservoir shakes out to some extent, sand gets into deep well pump, not only influences the deep well pump life-span, when serious the sand card can take place, and causes oil well to stop production.At present, gas anchor commonly used, sand anchor guarantee the oil well ordinary production: conventional gas anchor, sand anchor adopt liquid gas Gravity Separation and filter screen sand control, and be backward in technique, can not satisfy the needs of high oil-gas ratio, fine silt oil well gas-tight, sand control; Gas anchor, sand anchor separate use, make pumping pipe string complicated, all bring difficulty for schematic design and site operation, have reduced deep well pump pump efficiency and application life.
Summary of the invention
The purpose of the utility model is exactly the above-mentioned defective that exists to prior art, provides a kind of oil field well to use gas and sand anchor, has improved the pump efficiency and the application life of deep well pump, has improved production efficiency.
Its technical scheme is: mainly be made up of top connection, gas hood, jointing, upper pressing cap, interior screen casing, outer screen pipe, lower pressing cap, lower contact, tracheae; Top connection connects lower contact through jointing; Between top connection and the jointing tracheae is set, the tracheae top connects gas hood, screen casing and outer screen pipe in being provided with between lower contact and the jointing; The top of screen casing and outer screen pipe is provided with upper pressing cap in described, and the bottom of interior screen casing and outer screen pipe is provided with lower pressing cap.
The outer wall of above-mentioned tracheae is provided with helical blade.
The beneficial effect of the utility model is: can satisfy the needs of high oil-gas ratio, fine silt oil well gas-tight, sand control, integrate the anti-airway dysfunction of sand control, adopt inside and outside screen sand control, effective, permeability is high; The helical structure gas-tight, good separating effect, pump efficiency is high, has prolonged the application life of deep well pump, has improved production efficiency.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Among the last figure: top connection 1, gas hood 2, helical blade 3, jointing 4, upper pressing cap 5, interior screen casing 6, outer screen pipe 7, lower pressing cap 8, lower contact 9, tracheae 10.
The specific embodiment
In conjunction with accompanying drawing 1, the utility model is done further to describe:
The utility model mainly is made up of top connection 1, gas hood 2, jointing 4, upper pressing cap 5, interior screen casing 6, outer screen pipe 7, lower pressing cap 8, lower contact 9, tracheae 10; Top connection 1 connects lower contact 9 through jointing 4; Between top connection 1 and the jointing 4 tracheae 10 is set; Tracheae 10 tops connect gas hood 2; Screen casing 6 and outer screen pipe 7 in being provided with between lower contact 9 and the jointing 4, the top of described interior screen casing 6 and outer screen pipe 7 is provided with upper pressing cap 5, and the bottom of interior screen casing 6 and outer screen pipe 7 is provided with lower pressing cap 8; The outer wall of described tracheae 10 is provided with helical blade 3.
The utility model can satisfy the needs of high oil-gas ratio, fine silt oil well gas-tight, sand control, integrates the anti-airway dysfunction of sand control, adopts inside and outside screen sand control, and effective, permeability is high; The helical structure gas-tight, good separating effect, pump efficiency is high, has prolonged the application life of deep well pump, has improved production efficiency.
