Abstract
The utility model relates to an auxiliary pumping device for an oil well. The auxiliary pumping device for an oil well is provided with an upper joint 1 and a body 8 which are connected into an integral body by a thread. The valve ball 3 of a one-way valve and a valve seat 4 are arranged in the hollow interior of the auxiliary pumping device for an oil well. A fixed V-shaped sealing ring 6 and a spacing ring 7 are arranged on the outer part of the auxiliary pumping device for an oil well. The fixed V-shaped sealing ring 6 and the spacing ring 7 are provided with dummy clubs to be matched to make the dimension of the fixed V-shaped sealing ring 6 unchanged after the fixed V-shaped sealing ring 6 is installed. The auxiliary pumping device for an oil well is arranged on the middle part of an oil pumping rod, and the load and the bearing liquid column pressure of an oil pumping pump at the bottom of a well are reduced. The oil output of an oil layer is increased, and the yield of an oil well is increased. Sand discharge capability is enhanced when oil is pumped, the deposition of sand grains in the well is reduced, and thus, the phenomenon of sand clamping or sand burying is reduced.
Description
The utility model relates to from well producing oil, gas, water, solubilized maybe can dissolve material or slurry of mineral, particularly from the equipment of underground mining oil.
The producing well in oil field, when the pressure of oil reservoir reduces and can not blowing the time, then need to pump and produce oil, the equipment of this oil recovery is that a base valve is fixed on the shaft bottom, again that the oil well pump piston with one way valve that is connected on the sucker rod is following to the shaft bottom, on piston, under when moving, crude oil in the oil pipe can be mentioned on the ground, but this oil rig, the fluid column of its whole well depth all acts on the oil well pump, during oil well pump piston up stroke, walk long stroke and just can cause enough negative pressure that base valve is opened, crude oil just can enter oil pipe, so oil reservoir is fuel-displaced not smooth, oil production is low, in addition, piston is hard cooperation with cooperating of pump case, and contained sand grains enters and causes the pump wearing and tearing between piston and the shell in the crude oil, leakage of oil or stuck and akinesia causes the accident.Contained sand grains deposits in whole well depth in the crude oil, and the sediment outflow effect is bad.
The purpose of this utility model provides and a kind ofly can reduce the head of liquid that acts on the oil well pump, improve the discharge opeing ability of oil well pump, increase crude output, can in containing the crude oil of sand, work, increase the sediment outflow effect and can play the oil well pumping-assistant device of centralizing function sucker rod.
The purpose of this utility model realizes by following technical scheme, the oil well pumping-assistant utensil has top connection and body, top connection is connected as a single entity with this body and function screw thread and has the screw thread that is connected with sucker rod, it is characterized in that top connection is a hollow, inside is equipped with valve ball and valve seat, also has the passage with external communications, and body is a part hollow, cavity has the passage with exterior, and the outside of body also has with pressure ring fixing V-seal ring and spacer ring.
Fluted on the joint ring, boss is arranged on the spacer ring, groove matches with boss joint ring can not swelled after being subjected to thrust.
Below in conjunction with drawings and Examples oil well pumping-assistant device of the present utility model is explained in detail.
Fig. 1 is the elevation of the utility model oil well pumping-assistant device, and wherein part is analysed and observe.
As Fig. 1, the oil well pumping-assistant utensil has top connection 1 and body 8, top connection 1 is connected as a single entity with body 8 usefulness screw threads, top connection 1 top has upper internal threaded, body 8 bottoms have lower external thread makes exhausting-aid device can be connected to the centre of sucker rod and the appropriate depth that is positioned at oil well, top connection 1 is a hollow, cavity has passage 2 and exterior, body 8 is a part hollow, cavity has passage 9 and exterior, this passage 9 need be positioned at the below of outside seal ring, V-shaped ring 6 is equipped with in the outside of body 8, between sealing 6, each separates with spacer ring 7, the hold-down ring 5 that joint ring 6 and spacer ring 7 usefulness are threaded to be connected on the screw thread of body 8 is pushed down and is fixed on outside the body 8, spacer ring 7 has a boss and matches with the groove of V-shaped ring 6 and make not reason thrust and swelling of V-shaped ring, has valve seat 4 and valve ball 3 in top connection 1 inside, and they play one way valve.The outside of exhausting-aid device can directly contact with the internal diameter of oil pipe, and special-purpose pump barrel also can be arranged.
The quantity of V-shaped ring 6 is decided by the required degree of depth in well of exhausting-aid device, and then used quantity was some more when the degree of depth was big, and the material of joint ring 6 is oil resistant temperature resistant rubber or Polyurethane, and the external diameter of its tip should be greater than oil pipe or pump barrel internal diameter 2-4 millimeter.
During work, the oil well pumping-assistant device be connected to sucker rod the middle part and in the oil pipe of the desired depth of oil well, its V-shaped ring matches with the internal diameter of oil pipe or pump barrel and plays sealing function, when sucker rod moves up and down, the oil well pumping-assistant device also moves up and down in oil pipe, when up stroke, the valve ball 3 of exhausting-aid device is closed the hole of valve seat 4 under the head of liquid of top, so the liquid on exhausting-aid device top can be discharged outside the well, thereby the load of the oil well pump below having alleviated, and contained sand grains is promoted once more and can not be sink to the shaft bottom, when downward stroke, valve ball 3 is opened under the head of liquid effect below, and (it is motionless to be actually liquid and make liquid enter the top of exhausting-aid device, exhausting-aid device is descending), like this ringing and finish it and help the effect of taking out.
Oil well pumping-assistant device of the present utility model, externally contact with oil pipe is by V-shaped ring, good seal, and be difficult for by contained sand grains wearing and tearing or stuck in the liquid, so the crude oil that contains sand can be carried to well, joint ring 6 has the boss location with spacer ring 7, can joint ring not extruded the diameter ambassador's rapid wear that became because of thrust influences the life-span, and exhausting-aid device is installed in the appropriate depth of pumpingh well, and is also available a plurality of, reduced the load of shaft bottom oil well pump, and reduced suffered head of liquid, thereby made the liquid of adopting stratum flow in the well easily, thereby improved well yield, and the sediment outflow ability when pumping is strengthened, the sand card or the sand that have reduced oil well bury phenomenon.
Claims (3)
1, the utility model is the oil well pumping-assistant device, it has top connection 1 and body 8, top connection 1 is connected as a single entity with body 8 usefulness screw threads, it is characterized in that top connection is a hollow, inside is equipped with valve ball 3 and valve seat 4, also has the passage 2 of cavity and exterior, and body 8 is a part hollow, cavity has the passage 9 with exterior, and the outside of body 8 also has V-shaped ring 6 and the spacer ring of fixing with pressure ring 57.
