Abstract
The utility model relates to an underground locking and fixing device used for plunger gas lift, which is applied to plunger gas lift oil extraction for an oil gas well, and comprises an upper joint, a locking and fixing assembly and a jolting body. The lower end of the upper joint is connected with the upper end of the jolting body through a screw thread. The outer wall of the jolting body is sleeved with a locking and fixing cylinder, and the lower part of the locking and fixing cylinder is connected with connecting rods with the cross sections to be in arc surface shapes. The two connecting rods are mutually symmetric. The inner wall of the lower end of each connecting rod is provided with a conical surface. The outer wall of the lower end of each connecting rod is fixed with a slip block. When the jolting body falls downwards, the outside conical surface of a jolting head of the jolting body enters the inner wall conical surface of each connecting rod to support the lower end of each connecting rod to expand outwards. A slip is braced by the jolting body to be articulated on an oil pipe wall. The jolting body falls downwards by steel wire salvage operation to shear and release a shear pin and continuously descends to brace the slip, and the slip is articulated on the oil pipe wall to limit the maximum falling depth of a plunger in an oil pipe, thereby the plunger is avoided falling down below the position of a working valve to cause the upper part of the plunger to be injected with gas.
Description
Technical field
The utility model relates to oil recovery technique field, oil field, and particularly the oil well plunger lift recovers the oil, and is a kind of special tool that the oil well plunger lift recovers the oil that is used for, and is a kind of down-hole fastening device of plunger lift.
Technical background
Sometimes adopt the gaslift method to recover the oil in the oil field,, provide a kind of pulsation gas-lift production pump as patent announcement CN2636685Y; Notification number CN200971772Y provides a kind of relay-type plunger lift oil recovery device of air.When the downhole production of plunger lift well, plunger damper need be fixed on tube inner wall, present plunger damper can be fixed on tube inner wall, but can not limit the maximum whereabouts degree of depth of plunger in oil pipe, plunger may drop to below the actuated valve position, cause in the plunger upper part gas injection, influence normally carrying out of gas-lift production work.
The utility model content
The purpose of this utility model is: a kind of down-hole fastening device that is used for plunger lift is provided, is used for the fixing of plunger lift producing well lower bumper, can finish slips and tube inner wall is stung tightly by the wire Launching and Bailing operation, reach the purpose of fixed bumper.
The technical solution adopted in the utility model is: be used for the down-hole fastening device of plunger lift, mainly be made up of top connection, shear pin, jarring body, fastening tube, screw and jump ring.It is characterized in that: top connection and jarring body have centre bore.There is internal thread the upper end of jarring body, and there is the jarring head lower end of jarring body, and the external diameter of jarring head is greater than jarring body upper end external diameter.The outer wall of jarring head is a cone-shaped.The be threaded upper end of jarring body, the lower end of top connection.Be with a fastening tube on the external wall of jarring, the fastening tube is an annular, and fastening tube bottom is connected with the connecting rod that the cross section is an arc surfaced.The fastening tube with can take being connected of connecting rod the welding, also fastening tube and connecting rod can be processed as one.The quantity of connecting rod is two, and two connecting rods are symmetrical.Inwall has the conical surface in the lower end of connecting rod.Outer wall is fixed with slip segment in the connecting rod lower end.The external surface of slip segment has slip insert.When transferring the jarring body, a jarring male cone (strobilus masculinus) of jarring body lower end enters the connecting rod conical surface of inboard wall, and support connecting rod lower end expands outwardly.The external surface of the slip segment that connecting rod lower end outer wall is fixing has slip insert, and slip segment is stung at tubing wall, plays fixation.
For after the jarring male cone (strobilus masculinus) of jarring body lower end enters the connecting rod conical surface of inboard wall, be not easy to withdraw from, make slip segment fixing more firm, on the inwall of connecting rod, internal projection is arranged.After a jarring male cone (strobilus masculinus) entered the connecting rod conical surface of inboard wall, internal projection can be stuck in the top of jarring head, and the jarring head can not withdraw from automatically.
Convenient for construction operation, adopt screw that jump ring is arranged in the lower end of connecting rod.
Convenient for construction operation, the connection of thread of the upper end of top connection lower end and jarring body has shear pin.
The beneficial effects of the utility model are: be used for the down-hole fastening device of plunger lift, finish slip segment and tube inner wall by the pulling operation and sting and fasten.By the wire Launching and Bailing operation, the maximum whereabouts degree of depth of restriction plunger in oil pipe avoids plunger to drop to below the actuated valve position, causes in the plunger upper part gas injection.Adopt special structure design, satisfied the needs of fastening snubber in the oil pipe.
