CN-122014235-A - Logging-while-drilling gamma-ray spectroscopy logging instrument probe

Abstract

The invention relates to the technical field of measurement while drilling, and discloses a gamma-ray spectroscopy logging instrument probe while drilling, which comprises a main body. The springs on the inner wall of the annular plate shrink and accumulate potential energy under the pushing of the annular plate, at the moment, the whole annular plate deforms into an ellipse under the action of the counter thrust, the spring extension part enables the springs connected with the springs to extend and accumulate potential energy, and then when the device is separated from the inner wall of the detection hole through rebound of the annular plate, the whole annular plate becomes circular under the reset potential energy of the springs in different states, so that the condition that the whole device swings and collides with the inner wall of the detection hole due to the action of the angle of a conveying wire and the gravity of the device when the device is positioned in the detection hole is reduced, the abrasion degree of a probe tube when the probe tube moves is reduced, and the whole quality of a gamma probe in the probe tube when the probe tube is detected is improved.
