The fault-block A11 in the A'Nan Oilfield of the Erlian basin is now at a high water-cut period, and its reservoir heterogeneity has severely affected development results. To accurately describe the reservoir and its through-going characteristics, this article establishes a structural model, a sedimentary microfacies model, and a microfacies-controlled petrophysical model, step by step, using facies-controlled modeling technology with multiple stochastic modeling methods and on the basis of study results on seism, logging, geology, and development performance. The correlation of analogy results between facies-controlled petrophysical parameters and direct petrophysical parameters reveals that the facies-controlled attribute model is more reliable in describing reservoir heterogeneity. The successful application in the A'Nan Oilfield shows that facies-controlled modeling technology can satisfactorily realize the petrophysical parameter analogy of reservoirs with quick-change sedimentary microfacies and severe heterogeneity, providing a dependable geological basis for the later development and adjustment of oil and gas fields.
