System for degassing muds and for analysing the gases contained in the muds

A system for degassing muds and for analysing the gases contained in the muds, the system comprising:

• a tank comprising a first inlet and a first outlet for the mud;
• feed means of the mud, connected to the first inlet of the tank;
• means for extracting the gases from the mud contained in the tank;
• means for injecting a carrier gas, connected to a second inlet of the tank;
• means for physico-chemical analysis of the extracted gases, connected to a second outlet of the tank, designed for the carrier gas and the extracted gases;
• synchronization means of flow rate regulating means;
• carrier gas injection means;
• and
• physico-chemical analaysis means,
• wherein the extraction means comprise an ultrasonic electroacoustic transducer, and the feed means for feeding mud to the tank comprise volume and the flow rate regulating means enabling a preset constant volume of mud to be guaranteed in the tank and enabling the flow rate to be adjusted to a preset constant value.
