The multistage efficient gas and sand anchor comprises a central tube, wherein 10 bowl-shaped ring filter screens are regularly welded on the central tube; one end of the central tube is connected with a lower joint; the other end of the central tube is connected with one end of the lower joint of a two-stage spiral separation device; threads in the other end of the lower joint are connected with a short shunt outer tube; a short shunt is installed in the short shunt outer tube; the short shunt is fixed in the lower joint by the threads; the short shunt outer tube is connected with a lower valve cover; the lower valve cover is internally provided with a check valve; the threads in the lower valve cover are connected with one end of a long shunt outer tube; the other end of the long shunt outer tube is connected with an upper valve cover; a long shunt is fixed in the upper valve cover by the threads; and the upper valve cover is internally provided with the check valve.
Description
Technical field:
The utility model relates to the oil field operation field, and used a kind of downhole oil-gas separation device is adapted at using in the pumpingh well.
Background technology:
At present, oil, the gas combined shaft is many especially, and the gas in the Oil/gas Well generally all contains severe toxicity, and the separative efficiency of oil, gas is low, makes pump contain most of gas, has greatly reduced the effect of pump, has a strong impact on oil well output.
The utility model content:
In order to solve the problem in the background technology, the utility model provides a kind of downhole oil-gas separation device---multi-stage, efficient gas and sand anchor, and its outside dimension is little, can satisfy the requirement of annulus logging, be particularly suitable for carrying out using in the pumpingh well of annulus logging, oil-gas separation efficiency is high, and through the gas that the multi-stage, efficient gas and sand anchor is separated, is discharged into oil sets annular space through steam vent, enter again designated lane, greatly reduced the gas in the pump, improved pump efficiency, thereby improved oil well output.
The technical solution of the utility model is: this multi-stage, efficient gas and sand anchor comprises central tube, 10 bowl-type ring filter screens are welded on the central tube regularly, central tube one end connects lower contact, the other end connects an end internal thread of the bottom joint of two-stage screw separator, bottom joint other end internal thread links to each other with the short shunt outer tube, short shunt is equipped with in short shunt outer tube inside, it is inner that short shunt is fixed on the bottom joint by screw thread, the short shunt outer tube links to each other with lower valve cover, in the lower valve cover ball-and-seat is arranged, lower valve cover internal thread connects long shunt outer tube one end, the long shunt outer tube other end connects upper valve cover, and long shunt is fixed in the upper valve cover by screw thread, in the upper valve cover ball-and-seat is arranged, same mechanism is overlapping, realizes double effects.
The utlity model has following beneficial effect: this is novel to be suitable for gas, oil ratio is 60～300m
3The pumpingh well of/t and 300～500m
3/ t pumpingh well, temperature＜120 ℃, maximum outside diameter φ 89mm, liquid stream minimum diameter φ 20mm; Three shunting gas-liquid mixture fluids greatly reduce gas in the pump, have improved pump efficiency, thereby have improved oil well output.
Description of drawings:
Accompanying drawing is half sectional view of the present utility model.
Among the figure 1, lower contact, 2, bowl-type ring filter screen, 3, central tube, 4, the bottom joint, 5, the short shunt outer tube, 6, short shunt, 7, lower valve cover, 8, ball-and-seat, 9, the long shunt outer tube, 10, long shunt, 11, ball-and-seat, 12, upper valve cover.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing: as shown in the drawing, this multi-stage, efficient gas and sand anchor comprises central tube 3,10 bowl-type ring filter screens are welded on the central tube 3 regularly, central tube 3 one ends connect lower contact 1, the other end connects an end internal thread of the bottom joint 4 of two-stage screw separator, joint 4 other ends in bottom link to each other with short shunt outer tube 5, short shunt 6 is equipped with in short shunt outer tube 5 inside, short shunt 6 is fixed on bottom joint 4 inside by screw thread, short shunt outer tube 5 links to each other with lower valve cover 7, in the lower valve cover 7 ball-and-seat 8 is arranged, lower valve cover 7 internal threads connect long shunt outer tube 9 one ends, long shunt outer tube 9 other ends connect upper valve cover 12, long shunt 10 is fixed in the upper valve cover 12 by screw thread, in the upper valve cover 12 ball-and-seat 11 is arranged, during actual the use, by buckleing in upper valve cover 12 1 ends of oil pipe connection, transfer to precalculated position in the well, under the swabbing action of pump, when gas-liquid mixture fluid is flowed through central tube 3 and bowl-type ring filter screen 2 by oil sets annular space, utilize the Gravity Separation principle, fluid flows downward and enters in the bowl-type ring filter screen 2, portion gas then is discharged into oil sets annular space by the filter screen come-up, gas-liquid mixture fluid through the initial gross separation of bowl-type gas anchor, under the swabbing action of pump, enter the lower end of two-stage screw separator---in the bottom joint 4, and rotate up mobile along the helical trajectory of short shunt 5, under the effect of centrifugal force, liquid is thrown toward the inwall of short shunt outer tube 6, upwards flow simultaneously, isolated gas is then along the inner tube of short shunt 6, enter in the ball-and-seat 8, and be discharged into oil sets annular space along the steam vent on lower valve cover 7 two sides, liquid after the shunting of too short shunting chamber enters upper screw, rotational flow on the screw of long shunt 10, under the effect of centrifugal force, liquid is thrown toward the inwall of long shunt outer tube 9, upwards flow simultaneously, isolated gas then enters in the spherical ball-and-seat 11 along the inner tube of long shunt 10, and be discharged into oil sets annular space along the steam vent on the upper valve cover 12 both sides inwalls, liquid enters oil pipe, is separated through the most of gas in the gas-liquid mixture fluid of three separation.Thereby greatly reduce the gas that enters in the pump, improved pump efficiency, improved oil well output.
