| 1 | Orientation detector of sources emitting radioactive radiation | US549482 | 1990-07-06 | US5073715A | 1991-12-17 | Rene Chuiton; Maurice Chemtob; Philippe Kissel |
| An orientation detector for radioactive sources is provided.Such detector comprises a homogeneous sphere containing six sensors arranged on three different diameters at a limited depth from the sphere surface. Comparison of the radiation received and differently attenuated by the material of the sphere makes it possible to deduce the angular disposition of the source relative to the detector. | ||||||

| A method and apparatus for detecting the orientation of downhole geophones are provided. A gamma ray source is secured to a casing enclosing a geophone such that the location of the gamma ray source with respect to the orientation of a geophone is known. The geophone is secured to tubing such that the orientation of the geophone with respect to the tubing is known. The tubing, with attached geophone, is secured downhole. A gamma ray logging tool is run the length of the tubing. The orientation of the downhole geophone is determined from the gamma ray log. | ||||||

| PURPOSE: To obtain accurate measured values by providing a system for measuring radiation of incidence to 6 pieces of sensors reacting to radiation coming in according to the characteristics having no relation to the direction of a radiation source. CONSTITUTION: A detection device is inserted in a A1 spherical body 7 and has six pieces of sensors 1 to 6 arranged at the same distance from the center and close position to the outer surface. The sensors 1 to 4 are arranged on meridional M of the spherical body and the sensors 2, 4 to 6 are arranged on the equator E perpendicular to the meridional. The sensors 1 and 3 are arranged along a pole line P accompanied by the center O and the sensors 2 and 4 are along the line Q and the sensors 5 and 6 are along another line Q'. The spherical body 7 is brazed on a mast which is on the extended line of the pole line P and fixed to a support stage. This support stage forms an automatic conveyor 11 on which the detection device is placed. A radiation source S emits a radiation beam toward the detection device, which need not be arranged in the direction of the source for performing measurement. So accurate and perfect measured values can be obtained. COPYRIGHT: (C)1991,JPO | ||||||

Détecteur d'orientation de sources radioactives (5). Il se compose d'une sphère homogène (7) contenant six capteurs (1 à 6) sur trois diamètres différents à faible profondeur. La comparaison des rayonnements reçus, différemment atténués par le matériau de la sphère (7), permet de déduire les angles d'azimut et de site (ϑ et φ) de la source. |
