Description
A kind ofly be used for oil reservoir logging and once go into the well and finish the device that cable and downhole instruments single or two well logging contents are connected fast.
At present, logging community does not generally use combination well detecting Instrument in open hole well, adopts the monomer instrument to go into the well, and to being connected of its winch cable and downhole instrument, all adopts original rope sling at home, the technology that sebific duct etc. fall behind, trouble, time-consuming; Be to adopt advanced electrode head harness, but long 20 meters of its body, use inconveniently that it is big that middle rubber electrode cable is followed the instrument wearing and tearing of repeatedly going into the well, and makes well logging cost of production height abroad; In cased well, its well logging content is less, generally all is one, two well logging content, and as using well logging electrode head harness, resemble with shooting high and bombard mosquito, also be a kind of very big waste.Connection for convenient list or two well loggings proposes the design on this basis.The purpose of this utility model is to overcome shortcoming part of the prior art and provides a kind of height to lack (18 centimetres of total lengths), more advanced cable head harness easy to connect and lower-cost.
The purpose of this utility model can reach by following measure:
If housing, the upper end is fixedly coupled plug, the mid-fixing pulling force seat of body, and the two establishes the post power bolt to be threaded; Its plug external has joint ring, screw thread as with other disjunctor sealing, be connected, interiorly put the electrode socket of insulation and the plunger that electric conductor passes through for room; The lower end of plug be two the footpath cylinders as plug, its big footpath is that electric conductor passes through cylinder, path is a multiedge cylinder; The pulling force seat is that two footpath cylinders are similar corresponding on two footpath cylinders and the plugs, the two put sleeve that endoporus mates multiedge cylinder, pulling force column sleeve in interior; Establish the conductor contact pin in addition as the body that is electrically connected between socket, plunger, and join with lead.
The purpose of this utility model can also reach by following measure:
In the above-mentioned housing is the multipath hole, establish joint ring between plug and housing wall, the pulling force seat is to be threadedly connected in the housing, and key body location is arranged between wall, insulated column has 7 axial holes beyond the Great Wall, and there is keyway on the side, is bumped into the location by self key on the plug, insulated receptacle is fixed by the opening elasticity shelves ring that is embedded on the inwall of plug upper end, and have on the socket with plunger on 7 corresponding holes; Sleeve after the installation is fixed by the opening elasticity shelves ring that is embedded on the end face on the plug; Put plate washer with holes in pulling force seat lower end, fix by the shelves ring that is embedded on the housing.
To be described in further detail the design below in conjunction with accompanying drawing:
Fig. 1 is that logging cable head harness overall structure is partly cutd open figure,
Fig. 2 is logging cable head harness part complete section and last A-A sectional drawing thereof,
Fig. 3 is contact pin on Fig. 2 (a 4) diagrammatic sketch,
Fig. 4 insulate on Fig. 2 that plunger (6) main is looked, left pseudosection,
Fig. 5 be Fig. 2 upper plug head (5) main look partly cut open, left view,
Fig. 6 is main complete section, the left view looked of Fig. 2 upper pulling force seat (12);
By shown in Figure 2, establish housing (10), the upper end is fixedly coupled plug (5), the mid-fixing pulling force seat (12) of body, the two is established with the pulling force bolt (9) that is threaded, and all adopts the anticorrosion stainless steel.Wherein plug (5) is a connector, and external have packing_seal ring (2) and a screw thread, as with can connect being tightly connected of part, put the electrode socket (3) of insulation and the plunger (6) that electric conductor passes through for room in it; The lower end of plug (5) be two footpath cylinders (18,22) as interior block head, the cylinder (18) that big footpath is passed through for electric conductor, path is multiedge cylinder (22).Pulling force seat (12) also is two footpath cylinders, and is similar with the last two footpath cylinders (18,22) of plug (5), and corresponding the installation, puts the sleeve (20) of connection on two multiedge cylinders, is many ribs hole and institute's external member coupling in the sleeve, in multiedge cylinder, pulling force bolt are placed in.If conductor contact pin (4) is as the body that is electrically connected between socket (3), plunger (6), contact pin (4) also joins with lead (8).
In the above-mentioned housing (10) is the multipath hole, and plug (5) is gone up cylinder and is seated in the housing (10), establishes packing_seal ring (7) between wall; Pulling force seat (12) is with on the inwall that is threadedly connected to housing (10), and keyway (17) arranged with key (11) location between wall; In insulation plunger (6) 7 axial holes are arranged, there is keyway (14) on the side, and plug (5) is gone up self key (15) and is bumped into the location, with anti-rotation; Have on the insulated receptacle (3) with plunger (6) and go up 7 corresponding holes, fixing by the opening elasticity shelves rings (1) that embed on the inwall of plug (5) upper end.For increasing the whole erection mechanical performance, between plug (5), pulling force seat (12), put pulling force bolt (9), twist on two axle center screwed holes, relatively rotate for preventing the two (5,12), put sleeve (20); Sleeve after the installation (20) is fixed by the opening elasticity shelves rings (19) that end face is embedded on the plug (5); And put plate washer with holes (13) in pulling force seat (12) lower end, fix by being embedded in housing (10) ring (21) that performs.
Earlier pulling force bolt (9) is twisted on pulling force seat (12), cover upper bush (20) connects plug (5), and shelves rings (19) are installed; After plug, pulling force seat be connected as a single entity, be inserted in from housing (10) and screw on; Plunger (6), socket (3) and plug and lead (8) are loaded in plug (5) upper chamber in advance, and lead (8) will pass from respective aperture, then key (11) are inserted, and plate washer (13) is fixing with the shelves ring.
The utility model has following advantage compared to existing technology:
Height short (18 centimetres of total lengths), weight little (3 kilograms), in use flexible, convenient; Employing is from close self-locking structure, and insulating properties are reliable, and easy installing/dismounting, increases work efficiency; And accomplish civilized construction, be to make cable be connected advanced connector with downhole instrument in the at present well logging.
