Application of facies-controlled modeling technology a case study of H54-H98 block

In order to accurately describe the reservoir physical property and its through-going characteristics, this paper establishes the sedimentary microfacies model and the microfacies controlled property model step by step using the facies-controlled modeling technology and on the basis of study results on geology, logging and development performance. The 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 H54-H98 block 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 or adjustment of oil and gas fields.
