Geological section modeling method based on drilling information and knowledge inference technology

Abstract

The invention discloses a geological section modeling method based on drilling information and the knowledge inference technology. A drilling database stores all acquired dotted drilling bottom layer information data; drilling data in the database is converted into a lamellar logic data structure through a data converter; an inference machine infers stratums meeting conditions through combination of lamellar logic data and the knowledge inference rule in a knowledge base; a method class is a set of method sets mapping the stratums and geometric objects; an object assembler links the stratums inferred by the inference machine into a vector polygon chain, and finally a geological section graph is formed and fed back to a user through a graph interface; maintenance of the knowledge base is achieved through a knowledge manager. Intelligent decision making of the user on the section modeling algorithm and the section graph is achieved, and the problems that a traditional geological section modeling system is not high in accuracy and practicality due to the fact that expert knowledge and experience for decision making cannot be fused are solved.

Description

technical field [0001] The invention belongs to the technical fields of engineering calculation and GIS, and specifically designs a geological section modeling method based on drilling information and knowledge reasoning technology. Background technique [0002] Section modeling technology is a computerized stratum structure modeling technology. At present, most of the existing geological section modeling systems adopt the method of automatic tangent point and manual auxiliary map connection. This method can solve the problem of simple ore body and fixed number map connection. , but it is difficult to solve the tracking problem of complex geological boundaries or engineering boundaries. Stratigraphic division should be based on geological interpretation methods, but how to integrate geological interpretation and expert experience is a difficult problem in section modeling technology. So far, research in this area has not yet made a breakthrough. [0003] Generally speaking...
