Graduation system and method for lithologic density instrument

Abstract

The invention discloses a graduation system and a graduation method for a lithologic density instrument, which are used for overcoming the defect of high radiation on working personnel during gradation of the conventional lithologic density instrument. The system comprises a linear track, a lighologic density instrument, a magnesium block and an aluminum block, wherein the lighologic density instrument is arranged on the linear track; and the magnesium block and the aluminum block are arranged on an extension line of the linear track along the same direction. Due to the adoption of the system and the method, the graduation time of the lighologic density instrument is shortened remarkably, the graduation workload is lowered, the exposure time of working personnel in a radioactive space is shortened, and the safety conditions of the working personnel are improved remarkably.

Description

technical field

[0001] The invention relates to a lithology density instrument calibration technology, in particular to a lithology density instrument calibration system and method. Background technique

[0002] When performing secondary (workshop) calibration on existing lithology density series logging tools, two basic parts, magnesium block and aluminum block, are generally used, and there are two methods of vertical calibration and horizontal calibration. The vertical scale method is to use hoisting equipment to lift the instrument vertically, while the horizontal scale method is to place the instrument horizontally on the rail car through the rail car. In these two methods, the magnesium block and the aluminum block are placed side by side on one track, and the density instrument is set on the other track, and the two tracks are placed at 90 degrees. When grading, it is necessary to place the lithological density instrument in the magnesium block vertically or horizont...
