Problems solved by technology

In mud logging, mud logging gas flows at a high speed and its composition changes in real time. Its thermal conductivity and heat capacity are much lower than those of metals. It will be very difficult to make it heat up rapidly and keep a constant temperature in a limited space and a very high sample flow rate. Combined with Flowing gas pressure control, purification treatment and other procedures, the realization of the whole system is full of difficulties
[0004] To sum up, in order to realize the application of Raman spectrometer in the field of field logging and gas logging, it is necessary to solve the problem that the measurement environment affects the detection results

Abstract

The invention provides a Raman spectrometer measurement environment control method and system. The system comprises a Raman spectrometer temperature control system and a sample purification and flow and pressure control system. The Raman instrument temperature control system comprises a Raman spectrometer sample gas micro heater, a heat conductor temperature measuring meter, a gas temperature measuring tee joint, a gas temperature measuring meter, a Raman instrument optical path pool body, an optical path pool body temperature measuring meter, a temperature setting instrument, a PID (Proportion Integration Differentiation) operation program device, a regulator, a heater temperature controller and an optical path pool temperature controller. According to the scheme, the problems that a Raman spectrometer cannot adapt to the severe and changeable logging site environment, and the measured value is inaccurate can be solved.

Description

technical field [0001] The invention belongs to the field of mud logging gas component detection, and in particular relates to a method and system for controlling the temperature, pressure and flow of high-speed flowing gas, thereby realizing the unification of the measurement environment of a Raman spectrometer under various mud logging site conditions. Background technique [0002] Gas logging is the core technology of mud logging and the most direct and effective means to discover oil and gas layers. Its detection technologies are mainly hydrogen flame chromatography technology, thermal conductivity chromatography technology, and infrared spectroscopy technology. Due to their shortcomings such as long detection period, few detection indicators, and recalibration and correction when changing well positions, it is becoming more and more difficult to adapt to the complex oil and gas at the present stage. Tibet exploration work requirements. Raman spectroscopy has become one...
