MULTI-BEAM PHASED ARRAY ACOUSTIC TRANSDUCER OPERATION FOR DOWNHOLE APPLICATIONS |
摘要 |
An apparatus for imaging a borehole wall includes an array of acoustic transducers and a controller. The controller scans a section of the borehole wall with first acoustic beams that are transmitted by a series of sets of acoustic transducers in the array to produce adjacent first acoustic measurements that are spaced a first distance D1 apart along the borehole wall, each set having at least one transducer that is different from an adjacent set, (ii) steers a second acoustic beam along the section of the borehole wall using one set of acoustic transducers in the array to produce adjacent second acoustic measurements that are a second distance D2 apart along the borehole wall, and (iii) images the borehole wall using the first acoustic measurements and the second acoustic measurement to generate a borehole wall image, wherein at least one second acoustic measurement is between adjacent first acoustic measurements. |
