Abstract

The invention provides a reservoir heterogeneity research method based on a three-dimensional geologic model. The method comprises the following steps: step 1, making a statistics of all characteristic parameters of permeability according to a permeability simulated result of the three-dimensional geologic model; step 2, computing a heterogeneity characterization parameter of a single reservoir; step 3, computing a reservoir vertical permeability variable coefficient, and drawing a planar contour diagram of the reservoir vertical permeability variable coefficient according to a computation result. The method has innovativeness and practicability, is beneficial to promotion, and provides a feasible method for a heterogeneity characterization method based on the three-dimensional geologic model.

Description

technical field [0001] The invention relates to the technical field of reservoir heterogeneity research, in particular to a reservoir heterogeneity research method based on a three-dimensional geological model. Background technique [0002] Due to changes in factors such as sedimentation, diagenesis, and later tectonic movements, the lithology, physical properties, oiliness, and electrical properties of the reservoir show differences in three-dimensional space. This difference is called reservoir heterogeneity. Reservoir heterogeneity has an important impact on oil and gas accumulation, production and development, and the formation and distribution of remaining oil. Reservoir heterogeneity can be divided into interlayer heterogeneity, plane heterogeneity, intralayer heterogeneity and pore heterogeneity, among which interlayer, intralayer and plane heterogeneity belong to macroscopic Heterogeneity, while pore heterogeneity belongs to microscopic heterogeneity. In terms of r...
