A logging method for real-time automatic acoustic detection using logging system

Abstract

The invention provides a real-time automatic sonic logging method. The real-time automatic sonic logging method comprises the steps that firstly, an industrial computer sends a pulse signal to a stepping drive system; secondly, after receiving the pulse signal, the stepping drive system drives an underground detecting instrument to rotate in a set direction; thirdly, the industrial computer receives data collected by the underground detecting instrument in real time and display the data in real time; and fourthly, the industrial computer analyzes the received real-time data and judges whether detection is safe or not. Compared with the prior art, the real-time automatic sonic logging method can completely and accurately detect underground data and adjust the work direction of the underground detecting instrument in time according to the real-time sonic data and posture information, so that needed data can be obtained, errors are not prone to generation, and repeated measurement is not needed. An real-time automatic sonic logging system has a complete automatic drive capacity, can detect the sonic data and the posture information in real time, intelligently controls the underground detecting instrument to rotate, achieves the effect that detection does not need guidance of professionals and is easy to operate, small in size and convenient to carry.

Description

technical field [0001] The invention relates to the technical field of rock formation structure detection in engineering geophysical prospecting, in particular to a well logging method for real-time automatic sound wave detection using a well logging system. 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 p...

Problems solved by technology

When the rock formation is deep and the measurement points are dense, the measured position not only has a large error, but also takes a lot of time and effort

[0005] However, in the actual working environment, even if the location where the detection device collects the acoustic wave data of 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 for repeated measurements
