Abstract
The utility model provides a novel production screen. The novel production screen comprises an upper connector, a gas and sand anchor body and a sedimentation pipe, wherein the gas and sand anchor body is internally provided with the sedimentation pipe and fixedly connected with a fixed pup joint, a slotted pipe, a gas distribution pup joint and a lower connector screwed plug by welding. The novel production screen has the beneficial effects that after gas and liquid enter the gas and sand anchor body, the flow velocity is more stable, and the novel production screen is scientific and reasonable in structure, simple in manufacturing, high in strength and not easy to deform, overcomes the phenomenon of entangled threads which is extremely easy to occur in the downhole process of the production screen, so as to prolong the pump inspection cycle, effectively avoid the current situations of sand prevention and sedimentation stopping. The novel production screen is long in service life and low in cost, and the production efficiency of oil pumping can be improved.
Description
Technical field
The utility model relates to the oil pumping downhole tool, specifically a kind of novel oil production screen casing.
Background technology
In oil exploitation, during owing to the different exploitation of geology oil reservoir, enter in the oil well pump in order to stop the impurity such as silt, screen casing has played key effect, the easy sand card of the screen casing that uses in the prior art, gas lock, abrasion pump, leakage of oil, and cost is high, rub, disturb a phenomenon with borehole wall sleeve pipe, guide's poor-performing, shock resistance is poor, and supporting capacity is poor, the present situations such as oil impregnate efficient is low, thus impact is produced.
The utility model content
The utility model purpose provides a kind of novel oil production screen casing, and the effect that have the gear sand setting, stops foreign material to advance pump improves the oil pumper efficiency of pump.
In order to realize the utility model purpose, by the following technical solutions: it comprises top connection, gas and sand anchor body, sedimentation pipe, sedimentation pipe is installed in the described gas and sand anchor body and is welded and fixed and is connected with fixing pipe nipple, slot pipe, the joint of minute breathing hard, lower contact plug.Described sedimentation pipe diameter is greater than width.
The beneficial effects of the utility model are: after vapour-liquid enters the gas and sand anchor body, make flow velocity more steady, and scientific and reasonable for structure, make simple, intensity is high, and is not yielding, not yielding, overcome the sleave phenomenon that screen casing very easily occurs in the process of down-hole, thereby the prolongation pump detection period is effectively avoided sand control, the heavy present situation of gear, long service life, cost is low, has improved oil pumping production efficiency.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Be labeled as among the figure: 1 top connection, 2 gas and sand anchor bodies, 3 sedimentation pipes, 4 fixing pipe nipples, 5 slot pipes, 6 minutes joints of breathing hard, 7 lower contact plugs.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is further elaborated: it comprises top connection, gas and sand anchor body, sedimentation pipe, sedimentation pipe is installed in the described gas and sand anchor body and is welded and fixed and is connected with fixing pipe nipple, slot pipe, the joint of minute breathing hard, lower contact plug, terminate at pump intake on the gas and sand anchor body, when oil well oil-pumping, crude oil liquid saves in the annular space that enters downwards between sedimentation pipe and the gas and sand anchor body by breathing hard dividing under the slot pipe, and then liquid enters sedimentation pipe and upwards enters pump.At slot pipe place, because having pressure reduction to produce, separates slot, and the liquid that flows through has produced interference, the speed that the downward flow velocity of liquid must make progress less than bubble in institute's gas and sand anchor body, the gas that overflows are along entering sleeve pipe with the opposite direction of joint of minute breathing hard, after liquid enters sedimentation pipe, keep less pressure reduction, in order to reduce the frictional resistance of liquid, described sedimentation pipe diameter is greater than width, and the downward aisle spare of sedimentation pipe separates with flow rate of liquid.The utility model does not describe part in detail and is known technology, and the common variation that those skilled in the art carries out in the technical solutions of the utility model scope or replacement all should be included in the protection domain of the present utility model.
Claims (2)
