Abstract
The utility model provides a rigid connecting head harness. The mainly solves the problems that the existing head harness is connected by a soft electrode, is not easily salvaged, and single cores are not easy to be replaced when the single cores are damaged. The rigid connecting head harness is characterized in that a torpedo (7) whose outer wall is provided with a groove is clamped inside a salvage cap (1) by a fluorine rubber sleeve (12). The inner upper end of the centering blind hole (8) of the torpedo (7) is fixedly provided with a socket (6). An anti-rotating cap (5) is fixed on a polyhedron (10) on the upper part of the torpedo (7) by a screw (4). Upper single core joints (11) which are connected with the socket (6) are connected inside a plurality of through holes on the lower end surface of the torpedo (7). The lower end of the torpedo (7) is connected with a main joint (2) by a pulling force rod (3). Lower single core joints (9) which are connected with the upper single core joints (11) are connected inside through holes on the upper end surface of the main joint (2). The rigid connecting head harness has the advantages that the rigid connecting head harness has reliable connection and convenient salvage, and the single cores are easy to be replaced when the single cores are damaged.
Description
Technical field:
The utility model relates to oil reservoir logging field used well logging linkage, especially rigid connecting type head harness.
Background technology:
In oil reservoir logging work, land cable generally adopts head harness to be connected with downhole instrument.When present head harness is connected with cable, need soft electrode with a long 3-4 rice as changeover portion, being connected like this takes place in the work progress to go up when meeting the card accident, easily come off, owing on the head harness fishing bell the long soft electrode of 3-4 rice is arranged, fishing tool can't be salvaged, so this class engineering accident deals with very difficulty, makes construction cost increase, influence ordinary production, because existing head harness cable core connector is solid all-in-one-piece, when a single core damages, need integral replacing again, increased link cost like this, increase tie point, reduced the application life of equipment, increased the engineering accident hidden danger in the well logging work progress.
The utility model content:
Not easily changeable deficiency when connecting, being difficult for salvaging and the damage of single core by soft electrode in order to overcome existing head harness, the utility model provides a kind of rigid connecting type head harness, and this rigid connecting type head harness has to connect changes and salvage characteristics easily easily when reliable, single core damages.
Technical solutions of the utility model are: this rigid connecting type head harness, comprise fishing bell, major joint and chest-developing bar, fishing bell links to each other with major joint, be covered with the torpedo of outer wall belt groove in the fishing bell by the fluorine gum cover, the upper end is fixed with socket in the torpedo blind hole placed in the middle, torpedo top polyhedron has the anti-rotation cap by screw, be connected with the last single core joint that links to each other with socket on the torpedo lower surface in some through holes, the torpedo lower end links to each other with major joint by chest-developing bar, is connected with the core joint that places an order that links to each other with joint in some through holes of major joint upper surface.
Above-mentioned polyhedron is 6 bodies, and going up single core joint is 8, and the core joint that places an order is 11.
The beneficial effect that the utlity model has is: owing to be fixed with torpedo in the rigid connecting type head harness, link to each other with land cable by torpedo upper end socket, change hard connection into by being flexible coupling, torpedo connects, and makes to be connected firmly difficult drop-off, and salvage conveniently, prolong application life, improved the well logging success rate, shortened drilling period.The core joint that places an order by being threaded in the hole on the torpedo lower surface is connected with downhole instrument, when in the joint during some damages, can change at any time, reduce link cost like this, reduce tie point, prolong the application life of equipment, eliminate the accident potential in the well logging work progress.
Description of drawings:
Accompanying drawing 2 is the utility model A-A sectional drawings.
1-fishing bell among the figure, 2-major joint, 3-chest-developing bar, 4-screw, 5-anti-rotation cap, 6-socket, 7-torpedo, 8-blind hole, the 9-core joint that places an order, 10-polyhedron, the last single core joint of 11-, 12-fluorine gum cover.
The specific embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
By Fig. 1 in conjunction with shown in 2, this rigid connecting type head harness comprises fishing bell 1, major joint 2 and chest-developing bar 3, fishing bell 1 links to each other with major joint 2, be covered with the torpedo 7 of outer wall belt groove in the fishing bell 1 by fluorine gum cover 12, in the fishing bell 1 upper end step hole anti-rotation cap 5 arranged, be covered with torpedo 7 in the anti-rotation cap 5, torpedo 7 is a polyhedron 10 with anti-rotation cap 5 cooperation places, anti-rotation cap 5 is fixed on to beat by screw 4 with torpedo 7 and takes in the cap 1, prevents that torpedo 7 from rotating when work, causes and open circuit, the more important thing is and change hard connection by being flexible coupling into, torpedo connects, and is connected firmly difficult drop-off, and salvage conveniently, prolong application life, improved the well logging success rate, shortened drilling period; Torpedo 7 has blind hole 8 between two parties, is used to wear the connection lead; The upper end is fixed with socket 6 in the hole, and 6 of sockets make things convenient for land cable and are connected, and fix by the screwed hole on it; 8 holes are arranged on torpedo 7 lower surfaces, and 7 is through hole, and the hole internal thread is connected with single core joint 11, go up single core joint 11 and link to each other with socket 6, when single core joint 11 damages some like this, be convenient for changing by lead, reduce link cost, reduce tie point, prolong the application life of equipment; Torpedo 7 lower ends link to each other with major joint 2 by chest-developing bar 3,11 through holes that major joint 2 upper surfaces have, the through hole internal thread is connected with the core joint 11 that places an order, the core joint 11 that places an order links to each other with last single core joint 9 by lead, having solved existing single core joint is one, change the problem of inconvenience, reduce material cost, be convenient to operation.
