Problems solved by technology

[0008] The invention provides a method for intelligently reconstructing a 2D geological sequence model, which solves the problem of manually drawing POLYGON in the past to establish 2D geological models, and uses the superposition of POLYGON to describe special geological bodies. low, and often cannot describe the sequence pattern of sedimentation, which brings great problems to constraint attribute modeling

Embodiment 1

[0061] Such as Figure 1-Figure 6 As shown, the present embodiment provides a method for intelligently reconstructing a 2D geological sequence model, comprising the following steps:

[0062] Step 1: Draw horizon lines and fault lines;

[0063] Step 2: Identify the geological framework formed by the horizon lines and fault lines described in step 1, and establish framework information for the identified geological framework;

[0064] Step 3: Identify the topological structure of the framework information of the geological framework in step 2, and fuse the identified topology structure with the boundary information of the geological framework to construct boundary units;

[0065] Step 4: Track and identify the boundary units mentioned in Step 3, and apply the constraints of geological laws to establish a sequence model, realize automatic identification of geological bodies, and obtain 2D grid division diagrams and 2D geological models.

[0066] Such as Figure 7 , Figure 8 ...

Abstract

According to a method for intelligently reconstructing a 2D geological sequence model, the geological model is automatically established within a few minutes in an extremely short time basically without human intervention, the model is accurate, the efficiency is extremely high, it can be guaranteed that 2D modeling is achieved with correct sequence, high quality and high efficiency, and a remarkable technical effect is achieved; for a geologic body identified by the technology, stratigraphic sequence information can be quickly defined; sequence identification and mesh generation are automatically carried out. The problem that in the prior art, when a 2D geologic model is established, a POLYGON manual drawing mode is generally adopted, the efficiency is low, a sedimentary sequence mode cannot be described, and great difficulty is brought to later constraint attribute modeling in the mode that the drawn POLYGON is overlaid to describe a geologic body in a special form is solved.

Description

technical field [0001] The invention belongs to a 2D sequence modeling technology for petroleum geological exploration, evaluation and development, and in particular relates to a method for intelligently reconstructing a 2D geological sequence model. Background technique [0002] Since the publication of the world's first geological map of the geological structure and stratigraphic relationship of England, Wales and Scotland edited by the British geologist William Smith in 1815, 2D geological Figure 1 It has always been an important form of geological information. With the development of IT, especially the development of computer-aided mapping technology, GIS technology and 3D geological modeling technology, the expression of geological information has achieved great progress. [0003] In the field of reservoir exploration and development (including geophysical forward modeling, inversion, geological correlation, reservoir profile, etc.), sometimes in order to achieve more ...
