HRSG high resolution acoustic eight sectors logging tool
HRSG logging tool is a new multi-functional acoustic logging tool , it is a combination of the high- resolution acoustic logging tool and eight sectors acoustic logging tool through in function, could connect with HH2530 systerm by the TGR and electronic circuit 2 directly .
HRSG logging tool include as below : the short section of electronic circuit , acoustic probe and a short section of the low electronic circuit .
in barefoot well ,it could be with 2530-systerm instruments to do slam-combination logging .
In cased well ,it can be with TGR and Electronic circuit ,two combinations for sector cement bond loging.
