Description

Coupler of well logging torpedo

A kind of oil reservoir logging connection winch cable and device that adds long electrode, cable head harness of being used for.

Torpedo coupling on the borehole log bridle device that oil reservoir logging is at present both at home and abroad adopted is spindle-type overall structure or the left and right halved body structure vertically cut open, in be hollow tubular, 7 pairs of circuit sealing bodies are housed, be full of silicone grease.This kind coupling will be isolated the circuit sealing body from silicone grease during dismounting, trouble, time-consuming, unhygienic; Circuit sealing body two ends are the flexible cord body, arrange uneven easily crowded damaged bad; Poor sealing is arranged again, and external mud is easily invaded in the tube, reduces electrical insulation capability; This kind coupling can not separately use in addition, need be with to add long electrode and go into the well, and has increased electrode cable wearing and tearing number of times, reduces service life of equipment.

The purpose of this utility model is to overcome above-mentioned shortcoming part of the prior art and provides a kind of by pegging graft fixedly being connected of logging cable and electrode, easy accessibility, and the time lacks, and the upper and lower halved body coupling of insulation and good airproof performance.

The purpose of this utility model can reach by following measure: torpedo coupling housing decompose is gone up to the cable connection tube, is the electrode coupling tunnel down, in two cylindrical shells respectively with the cable seal body that has been threaded, electrode seal; Two seals middle parts be a cylinder, and the through hole of a plurality of correspondences is arranged on it, is packed into relatively and is fixed on it by the sealing-plug that goes between; Be stuck on the cable seal body on establishing the connection ring body between its cable, electrode container, the lower end combines as a whole two cylindrical shells to be threadedly connected on the electrode seal; In electrode seal upper chamber, adorn porous socket, insert by lead-in wire sealing-plug top electrode and form contact; And establish joint ring at each assembly building and order with the location spiral shell.

The purpose of this utility model can also reach by following measure: the hole that seven correspondences are arranged on the cylinder socket in cable, electrode seal, be that 1 hole is arranged on the coaxial inner conductor, uniform 6 identical holes on the circumference of axial line, and the hole in the cable, electrode seal is a screwed hole; Axial electric groove is arranged on the electrode seal, protrude the key body by cable seal body lower surface and insert the location.

Above-mentioned porous socket is an isolator, can be made by fluoroplastics, and be divided into upper and lower halved body, is connected as a single entity with double-screw bolt; The hole is bumped into the one copper sheathing on the body, and there is open slot vertically at the copper sheathing two ends, along circumferential flexible wiring; The mark of porose serial number on socket one end face, and upper and lower halved body top electrode grafting order groove is arranged on its side, there is the opening elasticity baffle ring that is set on the electrode seal inwall end; In addition, lead-in wire sealing both ends electrode is long and short different, and long end inserts on the socket and forms and electrically contacts.

Below in conjunction with accompanying drawing will the utility model is described in further detail:

Fig. 1 is a torpedo coupling overall structure complete section diagrammatic sketch

Fig. 2 is that the structure of cable seal (8) on Fig. 1 is partly cutd open figure

Fig. 3 be the structure master of Fig. 1 top electrode seal (6) look partly cut open, right view

Fig. 4 is that the master of porous socket on Fig. 1 (5) looks section, left view

Fig. 5 is that the master of Fig. 4 copper sheathing (20) looks, the A-A sectional drawing

By shown in Figure 1, it is the improvement to former torpedo coupling, promptly the housing of torpedo coupling is decomposed to go up and be the cable tube (1) of tie cable (4), down for connecting the electrode container (12) that adds long electrode (13), at two cylindrical shells (1,12) respectively with the cable seal body (8) that has been threaded, electrode seal (6), each assembly building has joint ring (9), also uses the screw (11) of band sealing mat in circumferential location in; At cable, electrode container (1,12) the interior upper and lower chamber that respectively has, the middle part is a cylinder, the tapped through hole that a plurality of correspondences are respectively arranged on it, each is screwed into relatively and is fixed on it by cable, contact conductor sealing-plug (7), it is long relatively extreme on the sealing-plug promptly to go between, and shortly extremely joins with cable or contact conductor on the contrary; And at electrode, cable seal body (6,8) there is keyway (17) key body (16) to insert the location on the body, axial keyway (17) is promptly arranged on the electrode seal, after the two is inserted mutually in the key body (16) that protrusion is arranged on the cable seal body lower surface, circumferential positioning action is arranged.

At cable, electrode container (1,12) establish connection ring body (10) between, the upper end is stuck on the interior combination cable seal body (8), the lower end is threadedly connected on the electrode seal (6), and two cylindrical shells (1,12) are connected as a single entity, two seals (8,6) be encapsulated in it, wherein the interior upper chamber of electrode seal (6) body is loaded on the interior lower chambers of cable seal body (8), and between joint ring (3) is arranged; Insert and form by lead-in wire sealing-plug (7) top electrode at the built-in fixing and directed porous socket (5) of electrode seal upper chamber and electrically contact.

Above-mentioned cable seal body (8) is two footpath ectosomes, and institute forms that ring platform and connection ring body (10) upper end are interior to be encircled boss clamping is identical mutually; On the cylinder in its cable, electrode seal (8,6) 7 screwed holes (15) are arranged respectively, that is: a screwed hole is arranged on the coaxial inner conductor, on the circumference of this axial line, be evenly equipped with 6 same holes, and upper and lower correspondence, 7 core holes be called; Porous socket (5) isolator can be made by fluoroplastics, and is divided into upper and lower halved body (19,21); Be connected as a single entity by double-screw bolt (23), have on it with cable seal body (8) inner cylinder on the corresponding through hole in hole, be called 7 core sockets, be bumped into one copper sheathing (20) in the hole, there is shaft orientation opening groove (24) at the copper sheathing two ends, wiring (22) is circumferentially arranged in the open slot upper edge, can be thin Elastic steel cable, with interior electrode banding, and on porous socket (5) upper surface porose serial number mark, i.e. electrode mark mark, and its external have on, the hold concurrently axial groove (25) of keyway of following halved body top electrode copper sheathing grafting sequencing, the pre-key (18) of inserting can be located, and (18) are one with part (6); Be fixed socket, be set in electrode seal inwall upper shed elasticity baffle ring (2) in its end; Porous socket (5) exposes the long end of electrode by lead-in wire sealing-plug (7) and inserts and forms and electrically contact, and short end of its electrode and cable, contact conductor (4,13) connection are encapsulated in the silicone grease (14).

The utility model has following advantage compared to existing technology: because cable and add long electrode and form by 7 spring hole scokets (5) and electrically contact, loading, unloading are convenient, only need one, two minute, and greatly improve work efficiency, and accomplish the comparison civilized construction; Respectively be provided with sealing ring in assembling place, guaranteed sealing property and insulating properties; This torpedo coupling is decomposed into upper and lower halved body, can separately use, and can use with electrode torpedo device and other matched with devices.
