Problems solved by technology

Restricted by the processing technology and other conditions, it is difficult to guarantee the uniformity of the inner diameter of the stainless steel air resistance wire. The length of the air resistance wire is artificially cut and intercepted, which also makes the dispersion of the air resistance flow large, which has great impact on the overall quality control of the product. problem
In addition, the length of the small flow stainless steel air resistance wire also brings troubles to the installation, which is not conducive to the modularization and standardized production of products

Abstract

The invention discloses a gas flow stabilizing device and a gas flow stabilizing method. The device comprises a gas sampling device, a filtering device, a pressure stabilizing device and a ruby gas resistor which are connected in sequence by a gas path pipeline; the pressure stabilizing device controls gas inlet pressure of a gas path system; the ruby gas resistor controls gas flow rate of the gas path system. According to the method, the gas flow rate of the gas path system is controlled by regulating the diameters of gas resistor inner holes formed in the center part of the ruby gas resistor, and length of the ruby gas resistor. According to the invention, precise and stable control of the gas flow rate in the gas path system can be realized within a wide temperature range from -40 DEG C to 150 DEG C; moreover, the device is simple in structure, convenient to install, stable in performance and low in cost.

Description

technical field [0001] The invention relates to a gas stabilizing device and a method for a petroleum logging gas analysis system, in particular to a gas stabilizing device and a gas stabilizing method. Background technique [0002] On-line gas chromatographic analysis technology is the core of oil and gas logging. It is used for continuous on-line analysis of drilling fluid gas (C1~C5 or C1~C8 hydrocarbon components) in the process of oil and gas exploration, and acts as the "eye" for oil and gas discovery. ", and provide accurate and reliable gas measurement data for service decision-making. In field gas logging, users put forward higher and higher requirements for the stability of the chromatograph, which puts forward new requirements for the performance of the gas chromatograph, especially the gas flow control of each gas path. [0003] At present, gas chromatographs generally use stainless steel gas resistance wires to control the gas flow of each gas path. As a kind ...
