Light type automatic rock-core gamma scanner

Abstract

The invention discloses a light type automatic rock-core gamma scanner and relates to the field of exploration equipment in the oil and gas field. The light type automatic rock-core gamma scanner disclosed by the invention has the advantages that a measured curve can be automatically printed, automatic prompting for lack of printing paper is achieved, automatic reprinting is achieved, and an accurate stepping motor is adopted for driving, so that the measurement repeatability is guaranteed; the input is realized by 128mm*64mm liquid-crystal panel and a keyboard, the operation prompting adopts Chinese characters, so that the convenient and practical effects are achieved; due to the USB host function, measurement files can be automatically stored to a U disk; the functions of high-energy pulse cutoff and low-energy pulse cutoff are achieved, a large-power power converter is arranged inside, and the maximum output current is 8A; an EEPROM non-volatile memory is arranged inside and can be used for storing data with 4K bytes; a 86-series large-powder stepping motor and a 7A driver are adopted and 16 subdivision is adopted, so that the smooth operation without step-out is guaranteed; and upper computer software is equipped to generate a site measurement curve, so that the processing and the viewing are convenient.

Description

technical field [0001] The invention relates to the field of oil and gas field exploration equipment, in particular to a portable automatic rock core gamma scanner. Background technique [0002] In the field of exploration and development of oil and gas fields, core data are the first-hand data for obtaining underground geological information, and the accuracy of core data directly affects energy exploration, production and scientific research. The core gamma exposure rate data measured on-site by the core gamma scanner can provide a basis for geological engineers to study the lithology, physical properties, electrical properties, and oil and gas properties of the formation, and has great significance for the formulation of on-site construction measures and the restoration of cores. Great directing. [0003] The existing traditional rock core gamma scanner is too large in size, inconvenient to carry, mediocre in measurement accuracy, and unable to run automatically and prin...
