Abstract
This device (53) comprises a pump (65) which comprises at least a fixed element (73) and at least a moving element (75) that can move with respect to the fixed element (73). These elements (73, 75) delimit at least one pumping cavity (77). The device (53) also comprises means (151) for heating the mud, these means being applied to the fixed element (73) and/or to the moving element (75) in order to heat said element (75). Application to the analysis of the gaseous content of mud resulting from the drilling of an oil well.

Device (53) for preparing a fluid, particularly a drilling mud, of the type comprising:
- a pump (65) comprising at least a fixed element (73) and at least a moving element (75) that can move with respect to the fixed element (73), these elements (73, 75) delimiting at least one pumping cavity (77);
- and
- means (151) for heating the fluid;
- characterized in that the heating means (151) are applied to the fixed element (73) and/or to the moving element (75) in order to heat said element (75).
Method for preparing a fluid, particularly a drilling mud, of the type comprising the steps of:
- pumping the fluid between an inlet (91) of a pump (65) and an outlet (101) of the pump (65), the pump (65) comprising at least a fixed element (73) and at least a moving element (75) that can move with respect to the fixed element (73), these elements (73, 75) delimiting at least one pumping cavity (77);
- and
- heating the fluid using heating means (151);
- characterized in that the heating of the fluid is performed by contact of this fluid with a surface (107) of the fixed element (73) and/or of the moving element (75) of the pump (65), this surface (107) being heated by the heating means (151).
