Title:
TRANSDUCER ASSEMBLY FOR OFFSHORE DRILLING RISER
Document Type and Number:
WIPO Patent Application WO/2018/035840
Kind Code:
A1
Abstract:
A transducer assembly for an offshore drilling riser (15) includes a spool (11) for connecting into the riser (15). A protrusion (31) having upper and lower sloping surfaces extends around the side wall of the spool. A recess extends around the protrusion between the upper and lower sloping surfaces. Upper transducer bores (47) are spaced around the protrusion and extend from the upper sloping surface downward and inward into the spool bore (19). Lower transducer bores (119) are spaced around the protrusion (31) and extend from the lower sloping surface upward and inward into the spool bore (19). A base (51) of a rigid non-metallic material is located in each of the transducer bores (47). A seal ring (65) extends around a cylindrical exterior portion (53a) of each of the bases (51) and one of the transducer bores (47). An acoustic transducer element (71) is mounted to the outer end of each of the bases (51). The transducer assembly can easily detect the parameter of drilling fluid flowing through the spool bore (19) and form a tight sealing.
