Well-logging isotope capsule and subpackage device used for same

Abstract

The invention discloses a well-logging isotope capsule and a subpackage device used for the same. The well-logging isotope capsule comprises a capsule body and radioactive isotope microspheres, the capsule body comprises a capsule main body and a capsule cap, the capsule body is filled with the certain weight of radioactive isotope microspheres, the capsule body has various specifications, and thesurfaces of the capsule main body and the capsule cap included in the capsule body are printed with two-dimensional codes; and the subpackage device comprises a shielding box, a cantilever-type manipulator, a machine vision system, a high-definition camera, an illuminating lamp and an operating control box. According to the capsule, the problem of different loading quantities in the process of loading the radioactive isotope microspheres into an isotope releaser is solved; and through the subpackage device, the problems that the radioactive isotope microspheres are missed and adhere to the isotope releaser, and adhere to the isotope releaser after releasing are solved, radioactive leakage is avoided, and radioactive damage of radioactive isotopes to operators and transport personnel is completely avoided.

Description

technical field [0001] The invention relates to the technical field of oil well logging tools, in particular to a logging isotope capsule and a dispenser for use thereof. Background technique [0002] Radioisotope logging is a logging method that uses artificial radioisotopes as missing agents to study and observe the technical status of oil wells and the status of oil production and water injection. The radioactive isotope microspheres are injected into the oil well with an isotope releaser during well logging, and the radioisotope microspheres form solid suspensions in the oil well, and are pressed into the channel outside the pipe or into the bottom layer or deposited in the filter along with the pressure of the releaser or water injection pressure. On the formation near the perforation tunnel, radioactive isotopes are used as tracer atoms, and gamma logging is carried out before and after. Comparing the curves before and after, we can know the characteristics of the form...

AI Technical Summary

Problems solved by technology

[0005] There are several problems in the current radioisotope method: 1. Because the radioisotope microspheres are very small and light in weight, the loading amount of each isotope releaser is different during the process of loading into the isotope releaser; 2. 2. Since the radioisotope microspheres are very small, in the process of loading the isotope releaser, due to the scattered loading, a small amount of radioisotope microspheres will not enter the isotope releaser but will be missed outside the releaser and adhered On the isotope releaser, it brings radiation hazards to the isotope releaser transportation and logging personnel; 3. Since the radioisotope microspheres are packed in the isotope releaser, after the isotope releaser releases the radioisotope microspheres in well logging, it still remains There are a small amount of radioactive isotope microspheres adhered to the isotope releaser, and the isotope releaser needs to be further processed. During this process, if care is not taken, it will still bring radiation hazards to logging and transportation personnel
