Downhole tool |
摘要 |
<p>A multi-part logging tool (10) comprises a tool body having a longitudinal axis (16), a first transducer (30) perpendicular to the axis, spaced second (32) and third (34) transducers at angles of 8 to 27 DEG to the axis (16), fourth (36) and fifth (38) transducers at angles of 8 to 27 DEG to the axis, and a sixth transducer (40) perpendicular to the axis (16). The tool allows measurement of several distinct independent parameters, which are in turn used to solve for secondary parameters that give information about the properties of the cement outside the casing. <IMAGE></p> |
