Abstract
The utility model provides a tension head harness used for the fast connection of the connection cable or the electrode and the underground logging tool in the well logging of the oil field. The main technical proposal of solving the existed problem in the prior art is that: a tension meter assembly is provided between an upper joint and a pulling force rod, and the tension meter assembly is arranged in an insulation balancing cavity; a circuit-board support assembly is arranged in a main body cavity, and is arranged in the main body cavity. The utility model solves the problems of that: the existing headstall can not reflect whether the instrument is clamped or the cable is bonded when the headstall is clamped under the ground, and the existing headstall can not reflect the stressing situation of the pulling force rod when the cable is released or shrunk. The utility model can be widely applied to the fast connection of the connection cable or the electrode and the underground logging tool in the logging operation of the oil field.
Description
Technical field:
The utility model relates to a kind of oil field and be used for the tension force head harness that stube cable or electrode and downhole logging instrument are connected usefulness fast in well logging.
Background technology:
What used in logging operation in present domestic oil field is the head harness of Purely mechanical, and its effect is that the realization cable is connected, protects when instrument is met card cable and instrument also conveniently to salvage with the quick of downhole instrument.Existing head harness can not reflect when meeting card in the down-hole that instrument is met card or cable bonds.At the stressing conditions of putting, can not reflect when receiving cable chest-developing bar.
The utility model content:
In order to overcome problems of the prior art, the utility model provides a kind of tension force head harness, it is to be provided with a chest-developing bar and tensiometer assembly in head harness, in the well logging process, when instrument is met card, can judge the reason of downhole instrument chance card, also can know the stressing conditions of chest-developing bar, provide subsurface information clearly to unfreezing work.
The technical scheme that its technical problem that solves the utility model adopts is: the tension force head harness adopts the tensiometer assembly directly to link to each other with chest-developing bar, and the tension variations of chest-developing bar is passed to ground by amplifier with the form of voltage signal.Understand the stressing conditions of chest-developing bar by continuous voltage change curve.If meeting card, the down-hole can conclude that it still is the cable bonding that instrument is met card.When card is met in the down-hole, when upwards receiving cable, if what obtain is that the straight line explanation pulling force that tensiometer reflected does not change with the tension variations of cable, this moment, chest-developing bar was not subjected to the pulling force of cable, the downhole cable bonding; If what obtain is the curve of a variation, illustrate that pulling force that tensiometer reflects changes with the tension variations of cable, this moment, chest-developing bar was subjected to the pulling force of cable, and instrument is met card.Size by power F can be had found a patron or superior appreciative of the ability the card degree, can according to circumstances take the unfreezing measure; Helmet is threaded with the top connection left end, and the top connection right-hand member is inner to be connected with tensiometer assembly left end internal whorl, and the outer end puts little six sides, puts a spring between top connection right-hand member outside and little six sides.Tensiometer assembly right-hand member is inner to be connected with chest-developing bar left end internal whorl, and the outer end puts big six sides, puts a spring between tensiometer assembly right-hand member and the big six side's left ends.The chest-developing bar right-hand member is threaded with main body, and the main body right-hand member is threaded with last shell left end, and last shell right-hand member is threaded with the thread protector left end, salvages the shell right-hand member and is threaded with the main body left end.Wiring board is placed in the main cavity its right-hand member ring that is locked and compresses, retaining ring is threaded with main body, balance capsule left end and top connection right-hand member galvanized wire bind, balance capsule right-hand member and main body left end galvanized wire bind, be full of silicone oil in the balance capsule and then constitute the insulation counter balance pocket, the tensiometer assembly is placed in the insulation counter balance pocket.
The utility model beneficial effect is: have maintenance period length, good insulating, volume little, in light weight, connect advantages such as rapid, alleviate labor strength, shorten aboveground well logging time.This tension force head harness also can accurately be judged the stressing conditions of chest-developing bar in the head harness of down-hole; If meeting card, the down-hole can conclude that it still is the cable bonding that instrument is met card.
