Abstract
The utility model discloses a novel well-logging bridle directly connected with a torpedo. The novel well-logging bridle directly connected with the torpedo is assembled by a torpedo female head, a positioning key, a connection rod, a salvage cap, a balancing tube, a glue sheath assembly, a blind point, a main body, a screw protector, a hexagonal sheath and the like. The novel well-logging bridle directly connected with the torpedo is characterized in that the torpedo female head is connected on the main body of the bridle via the connection rod and the blind point, a circuit pressure balance protecting system is formed by the balancing tube, the blind point is a separating structure of a cable and the bridle, an anti-rotating system is formed by the hexagonal sheath, and high-temperature tightness of the bridge is guaranteed by single-core double-groove sealing plugs and sealing rings. Well-logging capability of the bridle in deep wells and ultradeep wells is improved, safety and reliability of the anti-rotating system is improved, instrument falling accident caused by failure of the anti-rotating system is avoided, direction connection between a steel wire armored cable and the bridge is realized, outdoor construction of well logging is facilitated, and well-logging construction efficiency is improved.
Description
Technical field
The utility model relates to a kind of geological prospecting equipment, relates in particular to the direct-connected borehole log bridle of a kind of novel torpedo.
Background technology
Five sixties of eighties of last century cable all is to adopt steel wire loop to connect with being connected of downhole probe; Circuit connects the way that adopts colligation sebific duct or the wrapping of high pressure adhesive tape, and is original practicable again.The introduction borehole log bridle technology of Current Foreign Well Logging Technology progressively was applied and promotes along with 70 years last century, each apparatus manufacturer, and each oil reservoir logging company has developed the borehole log bridle that is fit to various downhole probe interfaces and various fisher in succession.Borehole log bridle is to be applied to oil gas field, Oil/gas Well to log well a standardization connection device realizing that steel wire armored cable is connected with downhole probe, it must possess following several functions: the standard interface that an elevated-temperature seal is arranged, the weakness structure that cable and head harness can be thrown off, anti-rotating function structure and salvage head has the circuit of good break-make and electrical insulating property.
Present various forms of borehole log bridle is summed up following three large series: introduce 3700 serial head harness of De Laisai company, the CSU series head harness of French Si Lunbeixie company, domestic 83 serial head harness; Wherein the price of import head harness is higher, uses not generally, and domestic 83 serial head harness are most widely used, and it is of a great variety, and form of structure is various, and every kind of form has excellent scarce place, and imperfection.
Summary of the invention
The direct-connected borehole log bridle spy of the utility model torpedo brings out one's strengths to make up for one's weaknesses for various types of quality place in the above-mentioned domestic 83 serial head harness, is intended to embody whole technical characteristics of borehole log bridle, consummating function.
The direct-connected borehole log bridle of a kind of novel torpedo described in the utility model comprises: helmet, jump ring, connector, torpedo female, positioning key, threaded collar, anti-back silk ring, connecting rod, fishing bell, balance pipe, gum cover assembly, single core double flute sealing-plug, weakness, fluting jackscrew, main body, 28 core plugs, threaded collar, sealing ring, thread protector, six square sets, jackscrew.It is characterized by: helmet and thread protector are respectively the guard blocks of torpedo female and 28 core plugs, prevent that wet gas from entering, and need remove during use; Jump ring is to be used for specially being connected the middle device that the torpedo joint is used with connector; Positioning key is the torpedo female and prevent the structure that it rotates mutually after connecting rod is connected; The torpedo female is connected on the head harness main body by connecting rod, weakness; Fishing bell is directly connected on the main body; Fill with silicone grease or silicone oil in the balance pipe, formed the circuit pressure balance protection system of this structure; Weakness is the disengagement structure of cable and head harness, when apparatus is stuck because of unexplained accident in the down-hole and utilizes cable to promote not come up, needs weakness to come disengagement structure; Six square set structures have formed the rotation protection system of this novel head harness; Single core double flute sealing-plug and sealing ring have been guaranteed the elevated-temperature seal of this new structure.
The direct-connected borehole log bridle of this novel torpedo has guaranteed that this bindiny mechanism possesses standard interface, elevated-temperature seal, weakness structure, anti-rotating function, salvaging head, break-make and insulating properties that circuit is good simultaneously.This new structure has not only improved the well logging ability of head harness at deep-well and ultradeep well, also improved the security reliability of rotation protection system, stopped to cause because rotation protection system is malfunctioning the instrument well accident that falls, the head harness upper interface adopts HYL38 type torpedo standard interface one torpedo female, realize the direct-connected of steel wire armored cable and head harness, convenient well logging field construction has improved the well logging efficiency of construction.

The specific embodiment
Below in conjunction with description of drawings the utility model is further elaborated.
The utility model is the direct-connected borehole log bridle of a kind of novel torpedo, comprising: helmet 1, jump ring 2, connector 3, torpedo female 4, positioning key 5, threaded collar 6, anti-back silk ring 7, connecting rod 8, fishing bell 9, balance pipe 10, gum cover assembly 11, single core double flute sealing-plug 12 and 25, weakness 13, fluting jackscrew 14, main body 15,28 core plugs 16, threaded collar 17, sealing ring 18 and 22 and 23, thread protector 19, six square sets 20, jackscrew 21.It is characterized by: helmet 1 and thread protector 19 are respectively the guard blocks of torpedo female 4 and 28 core plugs 16, prevent that wet gas from entering, and need remove during use; Jump ring 2 is the middle devices that are used for specially being connected torpedo female 4 usefulness with connector 3; Positioning key 5 is that torpedo female 4 is connected with connecting rod and is prevented the structure that it rotates mutually after connecting; Torpedo female 4 is connected on the head harness main body 15 by connecting rod 8, weakness 13; Fishing bell 9 is directly connected on the main body 15; Fill with silicone grease or silicone oil in the balance pipe 10, formed the circuit pressure balance protection system of this structure; Weakness 13 is the disengagement structure of cable and head harness, when apparatus is stuck because of unexplained accident in the down-hole and utilizes cable to promote not come up, needs weakness 13 to come disengagement structure; Six square sets, 20 structures have formed the rotation protection system of this novel head harness; Single core double flute sealing-plug 12,25 and sealing ring 18,22,23 have been guaranteed the elevated-temperature seal of this new structure.
During assembling, 28 core plugs 16 and gum cover assembly 11 and connecting line are installed in respectively on torpedo female 4 and the main body 15, then weakness 13 is connected on the head harness main body 15, and then connect anti-rotation six square sets 20, connecting rod 8, torpedo female 4, balance pipe 10, tighten balance pipe 10 two ends with iron wire after in balance pipe 10, filling with silicone grease when wherein assembling balance pipe 10, be loaded at last fishing bell 9, wait detect the two ends connecting line after, just can tighten thread protector 19, helmet 1, assemble complete.During specific works, remove first thread protector 19 and the helmet 1 at two ends, then connect on the corresponding head harness instrument of well logging usefulness, torpedo female 4 with connect above the cable instrument cab of having riveted torpedo male one end, after the energising, just can detect each layer material of down-hole under the data record, namely finish this logging program.
