The extraction of hydrocarbon gas is deaerated by the electric stirring type gas at vibratory sieve in domestic Conventional mud
Device and the quantitative degasser for occurring later（QGM）, the mud returned out using quick rotating vane or the continuous high degree of agitation pit shaft of impeller
Slurry stream, mechanical agitation is carried out to it and is crushed, and gas is separated from drilling fluid, is deviate from continuous acquisition outlet drilling fluid
Gas, then the gas that the gas transtracheal line that will be isolated with aspiration pump is pumped into remote instrument room from degasser is tested and analyzed
Detected for analysis in instrument.The method there are the defect of many inherences, and the degassing efficiency of stirring-type degasser is frequent at vibratory sieve
Can change because of the flow velocity of outlet mud, rate of discharge, mud liquid level height, drilling fluid density, viscosity and temperature, fluid type,
The influence of the factors such as gas type, gaseous state, causes the inconsistent of measurement result, causes sample volume and gas bleeding not
Unanimously, come difficult to measurement data and evaluation contrast attenation factor.Result causes its measurement to mud gas content to be inconsistent, non-
It is linear and qualitatively, and then quantitative contrast to oil/gas show data in similar well or region brings difficulty.
