Abstract:

Low resistivity reservoirs developed well in Mesozoic Yanchang Formation in norhtern Shanxi, with wide distribution and tremendous resource potential. But because of its complex genetic mechanism and diversified forms, the traditional method is difficult to identify them. Combining with the actual oilfield production practice, according to logging, well logging, experimental analysis and production test, with the main producing oil group as the research object, based on the comprehensive geological research, this paper studied the genetic mechanism of Chang 6 low resistivity reservoir in Zhidan and Ansai area, and discussed its identification methods. The results show that complex pore structure, clay with conductive ability and high water salinity are the main causes for Chang 6 low resistivity reservoir, and the methods of
crossplot, logging curve overlapping and adjacent water layer can be used to improve the recognition accuracy of the low resistivity reservoir in the study area.

Key words: passive wave field, common receiver gathers, energy anomalies in frequency domain, oil and gas prediction
