The fault-block Z2 in Jiangsu Oilfield developed at the end of 1995 is now at a middle water-cut period, and its reservoir heterogeneity is severe. In order to accurately describe the reservoir and its through-going characteristics, this paper establishes the structural model, the sedimentary microfacies model and the microfacies controlled property model step by step using facies-controlled modeling technology with the facies-controlled modeling technology and on the basis of study results on geology, logging and development performance.The comparison between facies-controlled modeling and non-facies-controlled modeling reveals that the facies-controlled property model is more reliable in describing reservoir heterogeneity.And the recovery ratio is enhanced by the comprehensive supervisory steps. The successful application in the fault block Z2 shows that the facies-controlled modeling technology can satisfactorily characterize the properties of the reservoirs with quick-change sedimentary microfacies and severe heterogeneity, providing a dependable geological model for the later development adjustment of oil and gas fields.
