Horizontal well geologic model construction system of underwater shunt channel single sand body configuration

Abstract

The invention discloses a horizontal well geologic model construction system of an underwater shunt channel single sand body configuration in the technical field of oil-gas exploration and development. The horizontal well geologic model construction system comprises a data management module used for acquiring data; the stratigraphic division module is used for establishing a stratigraphic framework; the logging facies module is used for logging facies analysis; the sand body identification module is used for identifying and classifying single sand bodies of the underwater diversion river channel; the sand body three-dimensional scale extraction module is used for obtaining a three-dimensional scale; the drawing module is used for extracting dominant types, forming a plane distribution diagram of sand body types and counting distribution of single sand body types; the sand body configuration analysis module is used for determining the three-dimensional scale of a typical sand body and performing configuration classification on the sand body; the permeability direction analysis module is used for acquiring permeability K values in different directions and determining the vector permeability of the sand body; the three-dimensional geological geometric model construction module is used for constructing a three-dimensional geological geometric model. According to the scheme, the influence of the permeability direction can be fully considered, and the precision of the geologic model is improved.
