Abstract
The utility model relates to a pushing electrode accessory for oil well resistivity logging device, in particular to a leather bag sealing device for through casing resistivity apparatus, comprising a seal base and a seal thimble. A leather bag is arranged between the seal base and the seal thimble which is fixed round the seal base through screws. The leather bag sealing device for through casing resistivity apparatus avoids that cloth for binding electrode is easy to wear and damage electrode insulating function, increases logging efficiency, ensures logging material quality, simplifies structure and construction, and is especially adaptable to pushing electrode of resistivity logging device.
Description
Technical field:
The utility model relates to oil well resistivity tool backup electrode accessory, especially a kind of TCR instrument leather bag sealing device.
Background technology:
The through casing resistivity logging technology be a kind of in cased well the new technology of Formation Resistivity Measurement, measuring voltage is to receive the volt level, investigation depth reaches 2 meters.This technology is not only important means and the combination of open hole well data of seeking remaining oil can also carry out the remaining oil saturation evaluation, is current state-of-the-art cased hole logging technology.
Leather bag is the main accessory on the through casing resistivity logging instrument backup electrode, and one group of totally 8 leather bag is arranged on every instrument.Each aboveground construction operation, leather bag flexible all more than 1000 times, so, damage than being easier to.Existing through casing resistivity logging instrument backup leather bag sealing position all is to tie up with cord, leather bag often occurs damaging or tie up tightly not reaching sealing effectiveness.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of TCR instrument leather bag sealing device that provides, can carry out positiver sealing to logger backup electrode, can not occur the packing less phenomenon of electrode tightly not occurring and influencing logging effect, thereby can guarantee logging data quality owing to tying up.
Technical scheme:
The task of Ti Chuing for achieving the above object, the utility model is finished in the following way.It is made up of seal receptacle, sealing thimble, between described seal receptacle and the sealing thimble leather bag is housed, and its sealing top needle guard is fixed with screw after going in the seal receptacle.
During assembling leather bag is inserted in sealing thimble skin, and then thimble penetrated in the seal receptacle, again thimble and seal receptacle firmly are fixed together by screw, get final product, because one group of totally 8 leather bag on every instrument, the leather bag of each aboveground construction operation flexible all more than 1000 times can constantly damage as using cord to tie up, can tightly not reach sealing effectiveness yet, help getting and get accurate well-log information entirely and use the utility model the leather bag phenomenon just can not occur damaging because of tying up.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Among the figure by 1, the sealing thimble, 2, the sealing top needle stand, 3, nut, leather bag (figure is mark) is formed.
The specific embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing:
In the drawings, this leather bag is made up of seal receptacle 2 and sealing thimble 1, seal receptacle is stainless steel material with the sealing thimble and makes, leather bag (figure mark) is that high temperature resistant a, high pressure and grease proofing elastomeric material are made, rubbery human body assembling back is housed between seal receptacle 2 and the sealing thimble to be fixed by screw, rubbery human body has not only guaranteed the insulated enclosure of telescoping ram electrode like this, and this device has high strength and high performance sealing function again in the work progress of down-hole, needn't worry instrument logging quality problem because of the bad appearance of insulating when measuring.
Claims (1)
1, a kind of TCR instrument leather bag sealing device, form by seal receptacle (1), sealing thimble (2), it is characterized in that: between described seal receptacle (1) inwall and sealing thimble (2) outer wall leather bag is housed, its sealing thimble (1) is fixed with screw (3) after being inserted in the sealing top needle stand (2).
