A system for sampling a drilling fluid exiting the wellbore in a portion of a flowline (25) having a substantially closed section, comprising :
- a first portion (80) connected in the closed-section portion of the flowline, comprising a closing device (88) movable between an open position in which the first portion defines a fluid passage between the outside and the closed-section portion of the flowline and a closed position in which the device closes the fluid passage,
- a second portion (90) configured to be inserted in the first portion , with the closing device in open position, defining a fluid passage between the outside and the closed-section portion of the flowline;
- a retaining device (106, 108) for fixing the second portion relative to the first portion,
wherein the second portion and the retaining device are configured so as to close the fluid passage defined by the first portion. |
