The case where raw well logging inserting tube is by card.If chip off-falling is larger to be staggered, using suddenly put or with winch strength promoted the methods of, meeting
Logging cable is broken at safety joint, stays in well logging inserting tube in hole, after cable is proposed drilling, needs individually to salvage survey
Exploratory shaft sinking pipe.
In the prior art, generally using internal diameter be greater than inserting tube outer diameter core barrel salvage, when under core barrel to inserting tube by card
Behind position, rotary drilling is needed, inserting tube is packed into after core barrel and proposes to drill, the relatively tight and core barrel blocked in hole due to inserting tube
Rotary drilling is needed, is easily damaged inserting tube in this way.
Utility model content
The technical issues of the utility model mainly solves in the presence of the prior art, thus provide it is a kind of it is easy to use,
Unfreezing effect is good and is less likely to be damaged inserting tube release device in the drilling of inserting tube.
Above technical problems of the utility model are mainly solved by the following technical scheme:
Inserting tube release device in drilling provided by the utility model, the inserting tube include inserting tube ontology and line interconnected
The top of cable, the inserting tube ontology is in the up-small and down-big frustum of a cone, and the release device includes tube body, connecting screw head and cable
Lock mechanism；
The lower part of the tube body offers up-small and down-big tapered opening, and the tapered opening and the frustum of a cone match
It closes, offers downward opening cable trough on the lower sides of the tube body；
The cable lock mechanism includes two elastic mild steel pieces being symmetricly set on the inside of the tube wall, two institutes
It states elastic mild steel piece and the cable trough encloses closed cable chamber, the cable blocks after the elastic mild steel piece to be placed on
In the cable chamber；
The connecting screw head is mounted on the top of the tube body, and the connecting screw head is connected with external drilling tool
It connects.
Further, the outer diameter of the inserting tube ontology is greater than the internal diameter of the tube body.
Further, the conical surface length of the tapered opening is greater than the conical surface length of the frustum of a cone.
Further, the outer edge of the tapered opening is equipped with arc protection face.
Further, two elastic mild steel piece side lower surfaces close to each other are additionally provided with guiding hemisphere block.
The utility model has the beneficial effects that: being placed on cable chamber by card after the cable of inserting tube is passed through elastic mild steel piece
In, then, the tapered opening of tube body and inserting tube ontology, to the top of inserting tube ontology, will be made in tube body tripping in drilling by drilling tool
Frustum of a cone phase fitting, then turn on pump and slowly lower brill, until driving inserting tube ontology loosening slowly proposes drilling tool after confirming unfreezing
Inserting tube can smoothly be proposed to drill.The utility model is easy to use, and unfreezing can be improved under the premise of not damaging inserting tube
Effect and the inserting tube unfreezing that can be suitably used for any depth.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the usage state diagram of inserting tube release device in the drilling of the utility model；
Fig. 2 is the structural schematic diagram of inserting tube release device in the drilling of the utility model.
Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear
Define.
Refering to fig. 1 shown in -2, inserting tube release device in the drilling of the utility model, inserting tube 1 includes inserting tube interconnected
Ontology 11 and cable 12, the top of inserting tube ontology 11 are in the up-small and down-big frustum of a cone 13, and release device includes tube body 2, connection spiral shell
Silk head 3 and cable lock mechanism；
The lower part of tube body 2 offers up-small and down-big tapered opening 21, and tapered opening 21 is matched with the frustum of a cone 13, tube body
Downward opening cable trough 22 is offered on 2 lower sides；
Cable lock mechanism includes two elastic mild steel pieces 4 for being symmetricly set on 2 inside sidewalls of tube body, two elastic mild steel
Piece 4 and cable trough 22 enclose closed cable chamber 5, and cable 12 blocks after elastic mild steel piece 4 to be placed in cable chamber 5；
