Abstract

Based on the comprehensive utilization of drilling data,logging data and 2-D seismic data,the authors hold that the tight reservoir of Yanchang Formation in Heshui area of Ordos Basin has developed a complex fault system consisting of strike-slip faults,fault damage zones and small-scale fractures,which together affect the heterogeneity and flow capacity of underground reservoirs,thus having an important impact on oil and gas production.So faults,fault damage zones and natural small-scale fractures should be treated as a system to analyze the fracture characteristics of ultra-low permeability reservoirs.The authors hold that only considering small-scale fractures is obviously not comprehensive.This understanding has important implications for the study of fractures in ultra-low permeability reservoirs in Ordos Basin.

Key words： fracture fault damage zone strike slip fault Heshui area
