Dynamic Reservoir Model And Remaining Oil Distribution Of Gasikule E31

To solving the relative problems of reservoir description and development plan regulation in the maturing field, taking Gasikule E31 oil reservoir as an example, with the residual oil distribution as center, this thesis makes an extensive study about the stochastic prediction modeling for the river facies sand-body, reservoir simulating and the regulation methods of improving water-flood efficiency adopting the methods of the combination of geology, log and reservoir development research, reservoir static prediction and performance analysis,reservoir performance research and reservoir simulation.Though the study, the thesis establishes the study program and the method system from stochastic modeling to reservoir development plan regulation,which has great significance on the theoretical research and practical application of reservoir description and development regulation in the maturing field.On the basis of establishing reservoir model, the thesis chooses the method of the combination of determinacy and stochastic modeling, which is a valid method for rebuilding the reservoir model, establishes the huge model of the reservoir and three-dimensional reservoir prediction model which provides a reliable qualitative geologic model for reservoir simulation. At the same time, according to the result of reservoir modeling,This thesis builds the reservoir parameter model by use of the upscaling, and through the study of reservoir simulation, the thesis describes the residual oil distribution qualitatively and quantitatively.Finally, through analyzing the development characteristic of Gasikule E31 oil reservoir, the thesis evaluates the production performance of this reservoir. The thesis gives some suggestions on development of Gasikule E31 oil reservoir, which are enhanced water-flood development, performing water injection profile control and water shutofF in the deep location,cyclic flooding test, and reservoir...
