Abstract：In order to examine the capacity using variation of impedance versus azimuth (IPVA) to detect the fracture and showing the author's development in an aspect of fracture detection,the paper detected the distribution of fracture in Luo-42 well zone of Shengli Oilfield. It is shown by drilling data in the region that the fracture-concentrated segment of S3 shale situated in the fourth oil shale of S3 shale. There are many fractural types and the proportion of structural fracture is maximum. Using simultaneously the IPVA method and structural fracture-predicted forward and inversion techniques to predict the distribution of fractures in the well zone,the predicted results of both methods are basically coincident and matched the analytic resuits of drilling data. It is further demonstrated by above results that the both methods have strong ability of fractural detection and four favorable targets are trapped，providing a benefit basis for exploration of fractured reservoir in the region.
