- Abstract
To meet the demand of detecting deep radioactive parameters in the deep scientific drilling of uranium deposit in China, new techniques such as high-temperature gamma spectrum detection, small-caliber integrated pressure-resistance and temperature-resistance, and new detector nuclear pulse signal acquisition have been innovatively developed to solve the technical problems of high-temperature and high-pressure resistance of gamma spectrum quantitative detection under small-caliber conditions. The measurement range of uranium content of the small-caliber high-temperature gamma-ray spectrometry logger is 100×10-6 to 5 000×10-6 . The temperature-resistant technical index is 130 ℃, which can work continuously for 10 hours and has been applied in the 3000m deep uranium scientific drilling at Xiangshan uranium ore filed and Zhuguang Changjiang No. 1 scientific drilling. This technology can provide technical equipment support for the exploration of uranium resources and the study of deep ore-forming environment.
