Description

Cable electrodes functional universal borehole log bridle device

Technical field

The utility model relates to the oil reservoir logging instrument, is used for when being specifically related to a kind of oil reservoir logging playing between winch cable and downhole probe that pulling force is connected and the head harness of electrical connection effect.

Background technology

The borehole log bridle device that at present domestic each oil reservoir logging company uses is to have copied many years ago by the borehole log bridle device of abroad introducing basically, when namely logging well, the cable torpedo must be connected with the electrode bridle assembly with the cable head harness respectively, then is connected with various downhole probes and just can completes test event.Each squad that logs well must be equipped with the two breeds of horses halter simultaneously, causes maintenance capacity large, and labor strength is also large.On the structure of head harness internal pressure balance, the overwhelming majority still adopts external early stage technology, utilizes rubber tube to do statocyst and add in inside and fills silicone grease and realize, this structural disadvantages is a lot, and technology is also relatively backward, is abroad eliminated already.Applicant in 2004 applied for once that name was called the utility model patent of " balance piston type well measuring headstall ", it is to utilize piston to do the trial of pressure balancing structure, but be placed in because of piston in the chamber at place, the thin neck of fishing bell footpath, the piston top is provided with the spring pushing, its activity space is narrow and small, mud rushes down does not go out, and following problem can occur in actual the use: 1, piston movement is obstructed; 2, repeatedly going into the well the mud that retains in back cavity can be with the dead dismounting difficulty that causes of piston; 3, be to be slidably matched due to piston and fishing bell barrel, during unfreezing, fisher will tighten the place, thin neck footpath of fishing bell, if cause the thin neck path position distortion of fishing bell, piston just may be stuck, affect normal unfreezing, therefore adopt the head harness unreasonable structure of this pressure balancing structure, field test results is unsatisfactory, facts have proved it is infeasible.

Summary of the invention

The purpose of this utility model is to use in logging operation for existing borehole log bridle device to cause maintenance capacity large, and labor strength is also large, and the irrational shortcoming of pressure balancing structure provides a kind of cable electrodes functional universal borehole log bridle device.

technical solution of the present utility model is: it comprises head harness, the upper end of head harness be provided with can with the cable torpedo that is fixed on the winch cable socket on the 15 core sockets that plug of 7 core plugs, it comprises that also lengthening soft electrode independent groups is fit, lengthen soft electrode independent groups zoarium by lengthen soft electrode and respectively fixing and locking torpedo under torpedo and electrode on the electrode of lengthening soft electrode top and bottom consist of, on electrode torpedo be provided with the cable torpedo that is fixed on the winch cable socket on the 7 core sockets that plug of 7 core plugs, under electrode, torpedo is provided with 15 core plugs that 15 core sockets with the head harness upper end plug.

Technique effect of the present utility model is: it has overcome the deficiency on existing borehole log bridle device technique, can economize on the use of funds, and reduces maintenance capacity, and can alleviate workman's labour intensity.It can make up the backwardness of present head harness internal pressure balanced structure with not enough, and the hidden danger of the normal unfreezing of eliminating the effects of the act, and result of use is more desirable.It unites two into one electrode bridle and cable head harness, can complete the test assignment of cable head harness and can complete the test assignment of electrode bridle again.

The utility model separates lengthening soft electrode and the electrode bridle that connecting electrode torpedo lower end, upper end is fixedly connected in the electrode bridle chamber, is designed to lengthen the soft electrode independent groups fit.The cable torpedo forms a kind of combination when being connected with head harness, survey the well logging project that does not lengthen soft electrode.Cable torpedo, lengthening soft electrode independent groups zoarium are connected with head harness and form another kind of combination, and surveying has the well logging project that lengthens soft electrode.

Because dummy piston is arranged in fishing bell lower semisection major diameter cavity, add in the fishing bell airtight cavity of dummy piston below and fill silicone oil, piston area is large like this, activity space is large, and piston can move up and down with the silicone oil variations in temperature in cavity freely, has good pressure balance performance; Survey completion mud and can gush from the mud on the fishing bell wall of dummy piston top and mouthful flow out, can not remain in dead dummy piston in fishing bell, cause the dismounting hard problem to be solved; The residing position of piston is not affect normal unfreezing in the large cavity of fishing bell.
