Description

A kind of down-hole is electronic gives up

Technical field: the present invention relates to petroleum production engineering field, oil field, belong to the electronic releasing device in a kind of down-hole.

Background technology: at present the oil field function that realizes giving up all is an engineering properties, and machinery is given up complicated on structure design, and technology is loaded down with trivial details, the realization process poor reliability of giving up, poor controllability, the tool using unification that matches can not realize the shortcoming that a kind of releasing tool cooperates many covers instrument to use.This device is a kind of electronic giving up, connect lower going-into-well by land cable at the bottom of, have and give up flexibly, controlled, convenient, fast with the tool combinations of putting into the down-hole for a long time, and rational in infrastructure, simple, satisfy the oil field to the functional requirement of giving up.

Summary of the invention: the purpose of this invention is to provide have give up flexible, controlled, with electronic the giving up in a kind of easily and efficiently down-hole of the tool combinations of putting into the down-hole for a long time.

Technical scheme of the present invention is: it is made up of connector, sealing ring, motor overcoat, motor, the anti-pivoted frame of motor, shaft coupling, power transmission shaft, fishing rod, adapter sleeve, anti-rotation pin, a location arm seat, plate, plate spring, spring washer, location support arm bearing pin, location support arm and location support arm torsion spring; Wherein the outer set upper side of connector lower end and motor is by being threaded, motor lower end in the motor overcoat prevents that with motor pivoted frame is by being threaded, motor is connected by shaft coupling with power transmission shaft, the power transmission shaft lower end is connected with end in contact on the fishing rod, motor overcoat lower end is by being threaded with the adapter sleeve upper end, the fishing rod lower end links to each other with an arm seat upper end, location, rotatablely move between an anti-rotation pin restriction adapter sleeve and the location arm seat, the fishing rod lower end contacts with the plate upper surface, the plate spring housing is on plate, plate lower end and spring washer upper end is by being threaded, the location support arm is connected by location support arm bearing pin with a location arm seat, and location support arm torsion spring is contained in the support arm of location.

Compared with the prior art the present invention has following advantage:

1), the present invention realized electronic giving up, have give up flexible, controlled, convenient, fast with the tool combinations of putting into the down-hole for a long time, rational in infrastructure, simple.

2), the present invention satisfied the requirement of oil field to the function of giving up, for the further exploitation in oil field provides a good technical support.

Description of drawings: Fig. 1 is a structural representation of the present invention

The specific embodiment: the invention will be further described below in conjunction with accompanying drawing, and it is made up of connector 1,sealing ring 2,motor overcoat 3,motor 4, theanti-pivoted frame 5 of motor,shaft coupling 6,power transmission shaft 7,fishing rod 8, adapter sleeve 9,anti-rotation pin 10, alocation arm seat 11,plate 12,plate spring 13,spring washer 14, location support arm bearingpin 15,location support arm 16 and location supportarm torsion spring 17; Wherein connector 1 lower end andmotor overcoat 3 upper ends are by being threaded,motor 4 lower ends in themotor overcoat 3 prevent that with motor pivotedframe 5 is by being threaded,motor 4 is connected byshaft coupling 6 withpower transmission shaft 7,power transmission shaft 7 lower ends are connected with end in contact on thefishing rod 8,motor overcoat 3 lower ends are by being threaded with adapter sleeve 9 upper ends,fishing rod 8 lower ends link to each other witharm seat 11 upper end, location, rotatablely move betweenanti-rotation pin 10 restriction adapter sleeves 9 and thelocation arm seat 11,fishing rod 8 lower ends contact withplate 12 upper surfaces,plate spring 13 is enclosed within on theplate 12,plate 12 lower ends andspring washer 14 upper ends are by being threaded,location support arm 16 is connected by location support arm bearingpin 15 with alocation arm seat 11, and location supportarm torsion spring 17 is contained in 16 li of location support arms.

During on-the-spot the use, at first the present invention is lowered into assigned address by well head, cable links to each other with connector 1 of the present invention, install to this by the terrestrial transmission signal of telecommunication,motor 4 is received signal and is started working,motor 4 outputting powers, byshaft coupling 6motor 4 is connected withpower transmission shaft 7,power transmission shaft 7 transmission power, becausepower transmission shaft 7 is enclosed within on thefishing rod 8, drivefishing rod 8 and rotate,fishing rod 8 is connected adapter sleeve 9 by trapezoidal thread with alocation arm seat 11, because the rotation offishing rod 8, makeplate 12 andfishing rod 8 grooves be in crossing condition,plate 12 is inserted infishing rod 8 grooves under the effect ofplate spring 13 power,location support arm 16 loses support, andlocation support arm 16 flicks under the supportarm torsion spring 17 elastic force effects of location; Following payout, this device moves downward, andlocation support arm 16 is supported on the positioning step of downhole tool;Control motor 4 is rotated further, andfishing rod 8 moves downward, and behind the rotation certain hour, adapter sleeve 9 is thrown off withfishing rod 8 screw buckles, realizes giving up.
