System and method for remote monitoring and fault diagnosis of logging system

Abstract

The invention relates to a system and a method for remote monitoring and fault diagnosis of a logging system and discloses a remote fault diagnosis system for the logging system. The system comprises a logging operation monitoring device, a maritime satellite, a ground satellite station and a control computer, wherein the logging operation monitoring device is coupled with the logging system and is used for monitoring and acquiring operation condition data of the logging system; the maritime satellite is coupled with the logging operation monitoring device and is used for sending the operation condition data; the ground satellite station is used for receiving the operation condition data sent by the maritime satellite; and the control computer is coupled with the ground satellite station and used for analyzing the operation condition data received by the ground satellite station and outputting fault status data of the logging system. The invention also discloses a remote fault diagnosis method, a remote monitoring system and a remote monitoring method for the logging system.

Description

Technical field [0001] The invention relates to long-range satellite communications for logging systems. More specifically, the present invention relates to the use of maritime satellites to realize remote service monitoring, remote fault diagnosis and maintenance, remote system control, and remote real-time data transmission of the logging system. Background technique [0002] Well logging, also called geophysical logging or petroleum logging, or logging for short, is a method of measuring geophysical parameters by using the electrochemical, conductive, acoustic, radioactive and other geophysical properties of rock formations. It belongs to applied geophysical methods. one. During oil drilling, well logging must be performed after the designed well depth is reached, also known as completion electrical logging, to obtain various petroleum geology and engineering technical data, that is, oil layer depth, thickness and other information, as the completion and development of the oi...

AI Technical Summary

Problems solved by technology

[0004] Since logging operations are generally in remote areas, the natural environment is harsh, and the communication conditions are poor. As far as a single oil well is concerned, all equipment and houses in the well site are temporarily built, and there is no wired communication network at all, especially in In sparsely populated areas such as seas, deserts, grasslands, and mountainous areas, even mobile phones have no signal; in some foreign areas, due to cost or security constraints, logging operations are generally only performed by local employees; remote services for logging systems Monitoring, remote fault diagnosis and maintenance, remote system control, remote real-time data transmission and other requirements cannot be realized at all
