Abstract
The invention provides a feeding and salvaging tool of an electronic single/multi-point measurement instrument suitable for gas drilling. The tool is mainly designed to solve the problem that the electronic single/multi-point measurement instrument cannot be directly plunged into the well during gas drilling, and aims to achieve the purposes of enabling the measurement instrument to realize the electronic multi-point data measurement and salvaging the electronic single/multi-point measurement instrument. The tool comprises a salvaging head, a salvaging guide shoe, a clamping jaw, a spring clamp, a pin, a clamp cylinder, a spring and a joint; the clamping jaw is fixed onto the salvaging shoe by the pin and the spring clamp; and the clamp cylinder is in threaded connection with the joint. The tool can not only be used for plunging the electronic single/multi-point measurement instrument into the well, but also serve as a tool for salvaging the electronic single/multi-point measurement instrument after being deprived of the joint, the clamp cylinder and the spring. Furthermore, the tool has the advantages of simple structure, convenient operation, low cost, good stability, adoption of mechanical structure and stable performance during use.
Description
Technical field
What the present invention relates to is that the used a kind of electronics list multimetering instrument of gas drilling that is applicable to of drilling engineering veers away and fishing tool.
Background technology
Yet carrying out before positioning operation begins at directional well, is to confirm straight well section track, needs to gather hole deviation, bearing data; Behind directed the end; Also need full well section hole deviation, bearing data checking hole trajectory data, this moment is if adopt the deviational survey car to measure, and cost is high, use duration; Electronics list multimetering instrument image data is a kind of convenience, accurate, economic method; This method has become a kind of common method in conventional drilling liquid boring method, and electronics list multimetering instrument drops in the well, reads the instrument record data after the trip-out.
Development along with the gas drilling technology is applied to directional well, horizontal well construction with the gas drilling technology and has obtained significant progress, when gas drilling; Owing to there is not the damping action of drilling fluid, if electronics list multimetering instrument is dropped in the well, instrument will descend near free-fall velocity; During to the shaft bottom; Decrease speed is very high, even adopted oscillation damping method, existing electronics list multimetering instrument also is difficult to bear so big impact shock.
At present, during gas drilling, need the full well section direction of deflection data of measurement to measure still and be measured as the master,, will reduce cost greatly, raise the efficiency if there is an instrument that electronics list multimetering instrument is veered away to the shaft bottom with the deviational survey car.
Summary of the invention
Use the problem that exists for solving gas drilling electronics list multimetering instrument; The invention provides a kind of electronics list multimetering instrument of gas drilling that is applicable to veers away and fishing tool; Form by fishing head, fishing guide, claw, Spring Card, pin, card tube, spring, several major parts of joint; It is characterized in that: claw is fixed on the fishing guide by pin, Spring Card, and the card tube is connected with joint screw thread.
The object of the present invention is to provide a kind of easy to operate, simple in structure, good stability and be applicable to that the electronics list multimetering instrument of gas drilling veers away and fishing tool.
The present invention also adopts following technical scheme:
The fishing head lower end has screw thread to be connected with electronics list multimetering cylindrical shell, and the upper end is the conical surface, and tapering is 60～90 °, and the inboard, upper end is an inner conical surface, and purpose is when the ratchet on the claw hooks fishing head, can not receive minor impact event to break off relations.The fishing guide lower end is a conical surface guide shoe head, and the middle part bilateral symmetry has axial groove, is used to install claw in the groove; Have the protection claw and carried or transfer in the process and impact, and leave two square openings, the lower end ratchet of claw hooks fishing head from here; Shoulder is arranged at top, acts on and block socket joint to touch, and prevents that fishing guide from coming off; Prap and wiring hole are arranged at the top, when changing fishing tool into, connect wire rope here.All there is ratchet at the claw two ends, and the lower end ratchet is to the inside, and is and corresponding with fishing guide middle part two square openings, be used for joining with fishing head, the upper end ratchet laterally, with and be complementary with a card conical surface.The card tube is a tubular structure, and top has screw thread and joint to join, and there is inner conical surface lower tubular inside.Joint is a tubular structure; The bottom has screw thread to be connected with the card tube, and the upper end conical surface, prap and wiring hole connect wire rope when veering away electronics list multimetering instrument; Joint not only plays the effect of connection; Also play and increase the weight of effect, be beneficial to the last ratchet that the electronics list multimetering instrument that veers away presses claw, open the following ratchet of claw.
This electronics list multimetering instrument veers away and the following advantage of fishing tool:
1, have two kinds of functions, the electronics list multimetering instrument that can veer away can be used as electronics list multimetering instrument fishing tool if remove joint, card tube and spring;
2, simple in structure, easy to operate, cost is low;
3, good stability adopts mechanical structure, and performance is played stably in the use.

The specific embodiment
Combine Fig. 1 that the present invention is done further description at present.The electronics list multimetering instrument that is applicable to gas drilling veers away and fishing tool mainly is during to gas drilling; Electronics list multimetering instrument can not drop in the well and design; To realize electronics list multiple spot DATA REASONING, also can realize the purpose that electronics list multimetering instrument is salvaged simultaneously.
This electronics list multimetering instrument veers away and fishing tool; Form by fishing head 1, fishing guide 2, claw 3, Spring Card 4, pin 5, card tube 6, spring 7, joint more than 8 major parts; It is characterized in that: claw 3 by pin 5, Spring Card 4 is fixed on the fishing guide 2, card tube 6 is threaded with joint 8.
When veering away electronics list multimetering instrument; Assemble by Fig. 1, and insert wire rope, fishing head 1 is connected to electronics list multimetering instrument rod member at joint 8 top wiring holes; And fishing head 1 inserted in the fishing guide 2, block fishing head 1 by the following ratchet of claw 3.By winch this instrument and electronics list multipoint instrument are sent into the shaft bottom, when instrument on earth after, under the effect of gravity; Joint 8, card tube 6 are descending, and promote the last ratchet of claw 3, and make ratchet block the inner conical surface of card tins 6; Claw 3 can open automatically and break away from fishing head 1 according to lever principle this moment, and because card tube 6 has locked claw 3; Following ratchet can't be connected with fishing head 1 again, trips out the instrument of veering away, and realizes that electronics list multimetering instrument veers away.
When electronics list multimetering instrument in the shaft bottom, owing to other reason can not rise when continue pulling out of hole, can adopt this instrument to carry out electronics list multimetering instrument and salvage.Before being lowered to instrument, assemble and not joint 8, spring 7 and card tube 6, wire rope is received in the wiring hole that drags on the guide shoe 2, at the bottom of the winch lower going-into-well by Fig. 1.After dragging for guide shoe 2 and finding fishing head 1, with down, the following ratchet of claw 3 is stretched out, and blocks fishing head at gravity, can on carry, realize the salvaging of electronics list multimetering instrument.
This tool construction is simple, easy to operate, dependable performance, can't throw in electronics list multipoint instrument operating mode when being specially adapted to gas drilling, also is applicable to that electronics list multipoint instrument is salvaged when boring the liquid drilling well simultaneously.
