Abstract

The invention relates to a geological knowledge base establishing method based on numerical simulation. The method includes: according to a mathematical equation and a boundary condition of hydrodynamics, superposing the deposition amount and the denudation amount which are obtained by simulating the hydrodynamic process and the sediment transmission process; obtaining a new sedimentary model, comparing and analyzing a simulation result and geological parameters of a target layer, performing geological dissection on the simulation result when the comparison and analysis results are consistent,extracting the geological parameters, and summarizing a geological phenomenon and a distribution rule of geological data, thereby establishing a corresponding geological knowledge base. Therefore, the material cost is saved, the constraint condition required by geologists to construct the geological model can be met, and the problem that the cost is high when a sedimentary physics simulation experiment is carried out through modern sedimentary investigation is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of oil and gas exploration and development, and in particular relates to a method for establishing a geological knowledge base based on numerical simulation. Background technique [0002] The geological knowledge base is an important constraint for constructing a fine geological model, which determines the quality and application of the geological model. Therefore, choosing an appropriate method to establish a geological knowledge base has important research significance in reservoir research. [0003] At present, the common methods of knowledge base construction and acquisition are generally through outcrop, dense well pattern anatomy or modern sedimentary investigation as the classic way of acquiring knowledge base parameters, and are used in the quantitative analysis and application of reservoir characteristics and heterogeneity at home and abroad. [0004] Outcrop dissection is mainly through detailed d...
