发明名称 Method and apparatus for detecting gas conveyed by drilling fluids
摘要 A method for detecting gas in a fluid, the system including flowing fluid bearing gas through a gas trap apparatus, flowing gas trapped by the gas trap apparatus to and through an infra-red gas detection system for detecting the gas, the infrared gas detection system having apparatus for isolating absorption spectra of the gas, producing with the infra-red gas detection system analog signals indicative of levels of the gas, transmitting the analog signals to a first processor for converting the analog signals to digital signals, transmitting the digital signals from the first processor to a second processor, producing with the second processor digital signals indicative of the level of the gas.
