摘要:
A gas-extraction device (52) for extracting at least one gas contained in a drilling mud, the device comprising an enclosure (62), an equipment (64) for supplying the drilling mud to the enclosure (62), and an equipment (70) for introducing a carrier gas into the enclosure (62). The device further comprises a flow regulator (104) able to regulate the flow rate of a gas flow containing at least carrier gas, and a pressure controller for locally setting a pressure distinct from the pressure of the enclosure (62). The flow regulator (104) is interposed between the pressure controller and the enclosure (62) and the pressure controller is configured so that the one of the pressure controller and enclosure (62) which is situated upstream from the flow regulator (104) has a higher pressure than the one situated downstream.
摘要:
The disclosure relates to a heat exchanger (100) for heating a drilling fluid, comprising : - an outer body (102) comprising an inner chamber (113) ; - an inner element (104) fitted in the inner chamber;
said inner element comprising a helical groove (144), said groove and a wall (112) of the inner chamber defining a path for the fluid ; and - a heating source (106) for heat exchange with said path ;
the inner chamber further comprising at least one opening (116), the inner element being able to be removed from the inner chamber through said at least one opening ; the outer body further comprising at least one removable lid (120) closing said at least one opening of the inner chamber.
