The axial direction of Kulongshan anticline in the south thrust belt of Qingxi Sag in Jiuquan Basin is accordance with the regional structural trend of NWW. However, the proved high oil abundance block of the structure spreads in the direction of NNE. The reservoir distribution is greatly dominated by the development situation of the deep fractured reservoir of Lower Cretaceous. Based on the core observation and description, the data of rock thin section, scanning electron microscope, X-CT scanning of whole-core and image logging, the fracture genesis, types and occurrence, including the spreading direction and the group systems of the reservoir of Lower Cretaceous Xiagou Formation are studied. Furthermore, the fractures distribution model is set up by the combination of test analysis data with image logging interpretation result and the seismic attribute analysis.
