Abstract
The invention discloses an oil drainage disconnecting-connecting device for oil field well repair operation and mechanical oil extraction. The oil drain part adopts a piston and sliding pin type; the separation part and the connection part adopt a cable tight sleeve type. The volume is reduced by one time compared with the prior art, the butt joint process is carried out in the pump cylinder, and the accuracy and the reliability of butt joint are better. When the oil pumping device works, the oil drainage part is arranged on the pump barrel, the butt joint rod of the disconnecting part is arranged on the plunger, and the five-claw spring is clamped on the first oil rod. The oil drain hole can be closed and the butt joint process can be finished as long as the sucker rod is descended. The oil drainage and disjointing process can be continuously completed by lifting the sucker rod. The above-described work can be repeated.
Description
The present invention relates to oil well repairing operation and mechanical oil recovery aspect.Specifically, be to be used for the device that oil pipe draining and the sucker rod and the plunger of deep well pump take off mutually, connect.
Usually bleeder and the on-off connector that adopts is two independent device.Its complex structure, volume is bigger, manufactures difficulty.
Oil-bleeding disconnector disclosed by the invention has two functions of draining and uncoupling, makes oil bleeding part and uncoupling partly become an indivisible organic whole.It simple and reasonable, oil bleeding part adopts piston, sliding pin type, and uncoupling partly adopts the tight shell type of rope.The volume ratio prior art is dwindled one times, and the uncoupling process is carried out in pump barrel, and the accuracy and the reliability of its butt joint are better.This kind oil-bleeding disconnector is made up of draining and uncoupling two parts.During work, oil bleeding part is installed on the pump barrel; The butt joint of uncoupling part is installed on the plunger, with the deep well pump G.I.H; Five pawl bullets of uncoupling part are connected on first sucker rod.Descending when five pawl bullet cards with sucker rod, during by the draining piston, just can close the draining hole.Be advanced in the pump barrel under continuing, and insert butt joint, finish docking operation.When needing draining and disconnection, need only and carry sucker rod, just can finish draining and uncoupling process continuously.
Describe details and the working condition that the present invention proposes in detail below in conjunction with accompanying drawing.
Oil bleeding part is made up of draining tube 1, draining piston 4 etc.; The uncoupling part is made up of five pawl bullet cards 11, butt joint 13 etc.When five pawl bullet cards 11 were descending with sucker rod, the sliding pin 3 that projection and the draining of its upper end lived on 4 contacted, and promotion draining piston 4 is descending, walking to spacing collar 7 ends, draining hole 6 is closed, and joint ring on the draining piston and the both sides that just in time are in draining hole 6 are to increase sealing effectiveness.In this moment, sliding pin 3 withdrew the cannelure of draining tube, the spring latch lock 2 on the sliding pin prevented that sliding pin from skidding off.Five pawl bullet cards 11 continue descending, enter pump barrel by draining piston 4, insert butt joint, promoting the tight cover 14 of rope simultaneously moves down, after the protuberance of recess in the five pawl bullet cards 11 and butt joint 13 coincide, rope tightly overlaps 14 and moved by using of thrust spring 15, and was tight five pawl bullet cards 11 and butt joint 13 ropes.Spring 12 in the five pawl bullet cards is the gaps that are used for adjusting between five pawl bullet cards and the butt joint, guarantees the reliability that connects.Need draining and when disconnecting, can on carry sucker rod, the protuberance of five pawl bullet cards, 11 upper ends is at first by sliding pin 3, the then following end in contact of the tight cover 14 of rope and draining piston 4, and drive on the draining piston and move is until draining hole 6 is opened.At this moment, sliding pin 3 skids off outside the groove, restPoses.Carry sucker rod in the continuation, five pawl bullet cards 11 with on move, and the tight cover 14 of rope is subjected to stopping of draining piston 4, moves on stopping, five pawl bullet cards break away from the lock ring of the tight cover 14 of rope gradually, finally break away from butt joint.Said process can repeat.Joint hoop 9, pipe nipple 10, packing ring 8, nut 16 are auxiliary accessories.
Claims (1)
1, a kind of oil pipe draining and sucker rod and plunger device of uncoupling mutually that is used for, it comprises draining and two parts of uncoupling, it is characterized in that: on the draining tube 1 cannelure is arranged, be drilled with draining hole 6 on every side, three bellmouths are arranged on the draining piston 4, taper sliding pin 3 is installed in the hole, and there is one group of spring latch lock 2 at the sliding pin middle part; There is the convex annular barring five pawl bullet cards, 11 upper ends of uncoupling part, in the spring 13 of adjusting play is arranged, rope tightly overlaps 14 and is positioned on the extension bar, can move up and down, it is tight or loosen the effect of five pawl bullet cards to play rope.
