Abstract

método para averiguar um furo subterrâneo, método para averiguar um espaço anular, método para analisar um espaço anular e método para monitorar um enchimento com cascalho subterrâneo. a presente invenção refere-se ao monitoramento de raios gama dispersos e é usada para identificar substâncias dispostas entre tubos coaxiais 412 dispostos em um furo subterrâneo 402. os raios gama são direcionados estrategicamente a partir do interior de um tubo mais interno 412 para o interior do espaço anular 422 e alguns dos raios gama se dispersam a partir da substância entre o tubo 412s e são detectados com os detectores ajustados em uma distância axial designada a partir da fonte de raio gama 428. os raios gama também se dispersam a partir do fluido no interior do tubo 412, uma razão dos raios gama detectados que se dispersam a partir do fluido no tubo 412 e a partir da substância pode ser usada para determinar a substância.method for ascertaining an underground hole, method for ascertaining an annular space, method for analyzing an annular space and method for monitoring a filling with underground gravel. the present invention relates to the monitoring of scattered gamma rays and is used to identify substances arranged between coaxial tubes 412 arranged in an underground hole 402. the gamma rays are strategically directed from the inside of an inner tube 412 to the inside of the annular space 422 and some of the gamma rays disperse from the substance between the tube 412s and are detected with the detectors set at a designated axial distance from the gamma ray source 428. the gamma rays also disperse from the fluid in the inside tube 412, a ratio of the detected gamma rays that disperse from the fluid in tube 412 and from the substance can be used to determine the substance.
