Background technology
If oil well brill before a lot of years (20～50 years) is difficult to guarantee the contact resistance (less than 0.1 Ω) that requires between electrode apparatus and the steel bushing.Because, the oxidation of steel bushing tube wall, corrosion or coking, wax deposition etc. in this case.The technology of the pipeline scraper plate device cleaning borehole wall that is adopted also usually can not obtain good result.
The method of measurement electrode backup is in the through casing resistivity logging instrument; Use soft electrode to connect; The hard alloy head of each electrode can move arbitrarily along borehole axis with being independent of each other; Casing wall has certain angle relatively, to hard alloy head pressurization and pressure release, pricks corrosion or coking layer in the sleeve pipe through continuous several times.Simultaneously, the currency according to measured parameter under two kinds of situation, the adequate condition of contact resistance is carried out detection of dynamic: on the uncontrollable current electrode of electrode system, do not have supply current (signal zero) and (or) to the uncontrollable power supply utmost point stream of supplying power successively.In less than 1 second to several seconds time; Release and recover pressure with automated manner or manual mode hard alloy head point; Make like this and can prick nonconducting corrosion layer (the similar iron chains head that beats usefulness) that the continuously smooth of measured parameter value reduces (reduce to one thousandth usually, to ten thousand/) to steady state value; All measurement electrode that electrode system is described are reliable with the sleeve pipe full contact, and almost 100% measurement situation is not always the case.This can make the backup time shorten, and can reduce a total Measuring Time in depth point.
Leather bag was the main accessory on the sleeve pipe measuring resistance rate logging instrument backup electrode; The fit sealing that had sleeve pipe measuring resistance rate logging instrument backup leather bag now is tied up realization with rope or steel band, and complicated operation is tied up not tight; Poor, the easy oil leakage of sealing effectiveness; And each aboveground construction operation, the flexible number of times of leather bag damages than being easier to more than 1000 times.
Summary of the invention
The purpose of the utility model provides a kind of TCR instrument backup leather bag, solves existing leather bag, needs tie up sealing with rope or steel band, and seal operation is complicated, ties up not tightly, and sealing effectiveness is poor, fragile, change problem such as workpiece complicated operation.
The technical solution of the utility model is:
A kind of leather bag comprises radiation fins, and the radiation fins end opening is provided with the leather bag bottom of extending to the radiation fins edge.
Turn up along the radiation fins radial direction in above-mentioned leather bag bottom.
The radiation fins of the above-mentioned leather bag leather bag top of extending that is provided with suitable for reading to the radiation fins edge.
Above-mentioned leather bag top is along turning under the radiation fins axial direction.
Above-mentioned leather bag bottom and/or leather bag top are provided with sealing device.
Above-mentioned sealing device is first outwards outstanding protruding ring muscle or first groove that caves inward.
Above-mentioned leather bag is outside equipped with retractable guard.
The utility model advantage is: the easy installation and removal between leather bag and leather bag seat, leather bag and the electrode, simple to operate, fit sealing is effective; Not easy oil leakage and not fragile, the seal operation that has overcome traditional leather bag and leather bag seat, leather bag and electrode is complicated, the problem of sealing effectiveness difference.
