Abstract: Remote detection acoustic reflection logging (RDARL) is capable to reflect acoustic impedance anomaly ranging from 3 to 10 meters beside a wellbore in carbonate formation or fractured-vuggy carbonate reservoir. This paper presents the detection principle and its typical response features applied to different types of reservoirs. Through the scale application of RDARL to Tarim carbonate reservoirs, integrated with conventional logging data, the fractured-vuggy developed situations of them beside the wellbores are evaluated. And the acid fracturing test shows that it can reach above 85% in effectiveness, increasing comprehensive capability of evaluating such a reservoir in this basin.
