Problems solved by technology

[0009] The technical problem to be solved by the present invention is that most of the existing numerical simulation methods for oil and gas reservoirs are relatively complicated when the reservoir grid is established, requiring the simulation personnel to have very solid professional knowledge and be very proficient in software application operations, otherwise it will be extremely difficult. Error-prone, resulting in the failure of the final numerical simulation, which undoubtedly raises the threshold for using reservoir simulation software and increases the difficulty of numerical simulation

Embodiment Construction

[0048] The following will combine Figure 1 to Figure 10 The three-dimensional formation modeling method based on the regular grid and corner grid technology provided by the present invention is described in detail, all of which are optional embodiments of the present invention. It can be considered that those skilled in the art will not change the spirit of the present invention Modify and polish it within the scope of its content and content.

[0049] It should be pointed out that the following examples describe the implementation process. In fact, the implementation of this part of the content still needs to be realized by programming with the help of OpenGL or other 3D graphics libraries. The method is to write the implementation program in advance, and input the corresponding The data, the model can be displayed after the background calculation, and here we hope to clarify the steps. In addition, OpenGL and the like are just some class libraries or function libraries, an...

Abstract

The invention discloses a three-dimensional stratum modeling method based on regular grids and corner-point grid technology. Firstly, according to elevation data for a stratum top/bottom interface in borehole data, regular grids for a stratum top/bottom interface in a certain research region is generated through interpolation algorithm, stratum thickness data in the borehole data are used for interpolation, stratum thickness regular grids for the region are generated, and the grid number is kept to be consistent; then, according to boundary coordinates and stratum pitching-out line data for the research region, a boundary file is built, and grids outside the boundary in the boundary file are removed; then, according to fault data, fault binding is carried out on stratum top/bottom interface regular grids; and finally, on the basis of the two kinds of regular grids, the corner-point grid technology is used for realizing three-dimensional stratum modeling.

Description

technical field [0001] The three-dimensional formation modeling method involved in the present invention, in particular, relates to a three-dimensional formation modeling method based on regular grid and corner grid technology. Background technique [0002] For a long time, researchers have attached great importance to geological modeling and visualization. As early as 1992, the International Association of Exploration Geophysicists and the European Association of Exploration Geophysicists established the SEG / EARG 3D Modeling Committee. In 1993, scholars from Canada SimonW.Houlding put forward the concept of 3D geological modeling, and elaborated some basic methods to realize geological 3D visualization technology, including triangulation generation method, triangulation surface model construction method, 3D triangulation solidification method, and boundary delineation of geological bodies and connections, etc., basically reflected the core achievements of the 3D visualizati...
