DEVICE FOR EXTRACTING AT LEAST ONE TYPE OF GAS CONTAINED IN A DRILLING MUD, AN ANALYSIS ARRANGEMENT AND A RELATED EXTRACTION METHOD

摘要

this device (53) includes a chamber (63), and means (65, 67)movement of the drilling fluid in the chamber (63). it also includesmeans (69) for introducing a carrier gas into the chamber (63).with a pipe (113) having a body (121) for adjusting the flow rate ofthe carrier gas. the device includes a pipe (53) to (71) of the gas extractionleading in the chamber (63). the introduction of a carrier gas (69).includes a sensor (123) for measuring the pressure in adownstream of the regulating device (121), and control means (117)flow rate of carrier gas injected through the regulating device (121), functionthe difference between the pressure measured by the sensor (123), and aextraction of gas pressure is determined.
