Problems solved by technology

Especially in the case of deep rock formations and dense measurement points, the measured position not only has a large error, but also takes a lot of time and effort
However, in the actual working environment, even if the position of the acoustic wave data collected by the detection device at each point is manually measured, due to the complex geological conditions around the well, it is impossible to detect the data completely and accurately, so errors are prone to occur during analysis, and cost A lot of time and effort to repeat measurements

Abstract

The invention discloses an automatic acoustic wave logging instrument and a method. The method comprises the steps that by using an encoder wireless location-measuring device, an acoustic wave logging energy transducer can track and record displacement values automatically in the moving process; according to a set displacement interval, automatic sampling is conducted, and collected acoustic wave signals are preserved; and by analyzing the acoustic wave signals, detecting and evaluating of the strength and defects of a rock stratum are realized, and accordingly integration of a measuring and analysis device and a sampling device and automation of the measuring process are achieved.

Description

technical field [0001] The invention relates to the technical field of rock structure detection in engineering geophysical prospecting, in particular to an automatic sonic logging instrument and a method thereof. Background technique [0002] Geology is one of the seven natural sciences, mainly concerned with the study of the earth and its origin and evolution. Practical applications are very extensive: earthquake prediction, search and exploration of various minerals, disastrous landslides, and evolution of paleontology. Among them, physical exploration is referred to as "geophysical prospecting", which is based on the differences in physical properties such as density, magnetism, electricity, elasticity, and radioactivity of various rocks and ores. Changes in the geophysical field are used to detect geological conditions such as stratum lithology and geological structure. The main geophysical prospecting methods are gravity prospecting, magnetic prospecting, electrical p...
