Abstract
A dual-lateral monitoring electrode assembly comprises a left end head, a first O-shaped sealing ring, a second O-shaped sealing ring, an inner pipe, a glass steel protection layer, three electrode rings, a fluorine rubber layer and a right end head. The first O-shaped sealing ring is arranged in a sealing groove formed in the left side of the inner pipe, the second O-shaped sealing ring is arranged in a sealing groove formed in the right side of the inner pipe, the three electrode rings are sequentially arranged on the inner pipe, the fluorine rubber layer is arranged on the outer side of the inner pipe, the glass steel protection layer is arranged outside the fluorine rubber layer, the left end head is arranged at the left end of the inner pipe through a thread, and the right end head is arranged at the right end of the inner pipe through a thread. Compared with the prior art, the dual-lateral monitoring electrode assembly has the advantages of effectively protecting the insulation between the end heads and the electrode rings, being simple in structure and good in wear resistance and waterproofness and effectively guaranteeing logging accuracy.
Description
Technical field
The utility model relates to the instrument component field of oil well logging, and especially a kind of bilateral is to monitor electrode assembly.
Background technology
Resistivity well logging is according to the method for the difference research boring geological section of rock stratum or ore body and shoulder-bed resistivity (SBR).When work, with cable, electrode system put into boring and move along borehole sections, by instrument record log.According to the difference of selecting electrode system, resistivity well logging is divided into again conventional electrode system resistivity well logging, microlog, laterolog etc.
At present, most of bilateral using in the time carrying out operation, does not have safeguard measure to monitor electrode device; often, due to the wearing and tearing of colliding with, not only affect the accuracy of survey data, but also can damage instrument; often operating efficiency has been lowered in maintenance or replacing, has improved the cost dropping into.
Summary of the invention
The purpose of this utility model is to provide a kind of bilateral to monitor electrode assembly; at inner tube outer setting one deck fluorine rubber ring of electrode assemblies; fluorine rubber ring outer setting glass fiber reinforced plastic topping; improve the wear-resisting and water resistance of instrument; wear-resisting and water resistance is improved, and has effectively ensured the accuracy of well logging.
For achieving the above object, the utility model is realized by the following technical solutions:
A kind of bilateral is to monitor electrode device, comprise left end head, O-ring seals one, O-ring seals two, inner tube, glass fiber reinforced plastic topping, electrode retaining collar, fluororubber layer, right-hand member head, described O-ring seals one is arranged in the seal groove in inner tube left side, and O-ring seals two is arranged in the seal groove on inner tube right side; Described electrode retaining collar quantity has three, sets gradually on inner pipe, and fluororubber layer is arranged on inner tube outside, and glass fiber reinforced plastic topping is arranged on fluororubber layer outside, and left end head is arranged on inner tube left end by screw thread, and right-hand member head is arranged on inner tube right-hand member by screw thread.
Compared with prior art, the beneficial effects of the utility model are:
1) can effectively protect the insulating properties between termination, electrode retaining collar.
2) simple in structure, abrasion resistance and good waterproof performance, has effectively ensured the accuracy of well logging.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is further illustrated:
As shown in Figure 1, a kind of bilateral is to monitor electrode device, comprise left end head 1, O-ring seals 1, O-ring seals 28, inner tube 3, glass fiber reinforced plastic topping, electrode retaining collar, fluororubber layer, right-hand member head, described O-ring seals 1 is arranged in the seal groove in inner tube 3 left sides, and O-ring seals 28 is arranged in the seal groove on inner tube 3 right sides; Described electrode retaining collar 5 quantity have three; set gradually on inner pipe, fluororubber layer 6 is arranged on inner tube outside, and glass fiber reinforced plastic topping 4 is arranged on fluororubber layer 6 outsides; left end head 1 is arranged on inner tube 3 left ends by screw thread, and right-hand member head 7 is arranged on inner tube 3 right-hand members by screw thread.
By the inner tube outer setting one deck fluororubber layer 6 at electrode assemblies, fluororubber layer 6 outer setting glass fiber reinforced plastic toppings, 4 have played the effect of protection, and wear-resisting and water resistance is improved, and has effectively ensured the accuracy of well logging.
