| description | Taking the Member 1 oil reservoir of Dongying Formation in Nanpu Sag as an example, this article puts forward an integrated study method for oil reservoir description and evaluation. First, with the correlation of seismic, log, and geological data, the isochronous stratigraphic framework of the oil reservoir is built up, sequence boundaries are interpreted, the sequence constrained prestack seismic inversion is processed, and a geological conceptual model of reservoir is established. Second, with the results of prestack seismic inversion and the Petrel software, the structure model of the isochronous stratigraphic framework and the quantitative geological database are built up. Third, through contrasting and selecting the most reasonable method of stochastic modeling, the reservoir facies modeling and the petrophysical modeling with the constraint of facies models are processed, the oil geological reserves are computed and evaluated, and some oil reservoirs are described finely. The study shows that the Member 1 oil reservoir is a layered, structure-controlled, edge water drive reservoir. It has thick sands, good properties, and complicated oil–water systems. The geological reserves estimated by the nine designed implementation models are the realization of Monte Carlo methods and conform to a certain probability distribution. The models are favorable for the reasonable evaluation of reserves. Key words: Nanpu No. 1 structure, Dongying Member 1 oil reservoir, integrated oil-reservoir description and evaluation, stochastic modeling under determinable constraints |
