Problems solved by technology

[0002] Existing infrared mud logging instruments are roughly divided into a drilling parameter acquisition part and an infrared gas analysis part. There is no automatic control function for the electric degasser. At the same time, the circuit structure of the existing technology is relatively complicated and the integration degree is low; the lower computer It only collects and displays the concentration values ​​of light and heavy hydrocarbons separately; there is no instrument that can simultaneously display and print the drilling time curve and the total hydrocarbon concentration curve in real time

Abstract

The invention relates to a total hydrocarbon intelligent logging system. A geologic parameter acquisition unit in drilling engineering, a tracking control unit of an electric degassing unit and an infrared total hydrocarbon gas analytic unit which adopt a standard industrial control chassis as a shell to form a drawer type structure are arranged in an integral machine cabinet with a computer host, a UPS power supply and a tool box simultaneously; the circuit connection thereof is as follows: the computer host respectively adopts an RS232 serial port and is bidirectionally connected with the geologic parameter acquisition unit in drilling engineering, the infrared total hydrocarbon gas analytic unit and the automatic tracking control unit of the electric degassing unit and the automatic tracking control unit of the electric degassing unit and the degassing unit are connected bidirectionally; the sampling of sample gas of the electric degassing unit enters the infrared total hydrocarbon gas analytic unit; and the infrared total hydrocarbon gas analytic unit is simulated and output by D / A. The system can simultaneously print drilling time curve and total hydrocarbon concentration curve and has compact structure, beautiful appearance, convenient installation, carrying, debugging and maintenance for the instrument.

Description

Technical field [0001] The invention relates to a geological parameter detection and analysis instrument, in particular to an all-hydrocarbon intelligent logging system. Background technique [0002] The existing infrared mud logging units are roughly divided into the drilling parameter acquisition part and the infrared gas analysis part. There is no automatic control function of the electric degasser. At the same time, the circuit structure of the prior art is relatively complicated and the integration is low; It only collects and displays the concentration values ​​of light and heavy hydrocarbons separately; there is no instrument that can display and print the drilling time curve and the total hydrocarbon concentration curve in real time at the same time. Summary of the invention [0003] The purpose of the present invention is to provide a new infrared logging instrument that integrates drilling geological parameter acquisition, infrared full hydrocarbon gas analysis and aut...
