Abstract

The invention provides a modeling method and system of a geologic model, and solves the problem that most of the geologic modeling work is guided by a fault-related fold theory, is mainly carried out for a thrust belt of thin belt development, and cannot be suitable for a mountain-front thrust belt of transition belt development. The modeling method of the geologic model comprises the following steps: selecting a seismic section, and converting the seismic section into a depth modeling seismic section; obtaining a surface geology actual measurement profile based on the seismic profile; obtaining a structure modeling interpretation scheme based on the depth modeling seismic section and the surface geology actual measurement section; modifying the structural modeling interpretation scheme based on a structural deformation mode to obtain a preliminary interpretation scheme of the modeling seismic section; and adjusting the preliminary interpretation scheme to obtain a geologic model.

Description

technical field [0001] The invention relates to the technical field of modeling, in particular to a modeling method and system for a geological model. Background technique [0002] The piedmont area has always been an important position for my country's oil and gas exploration to seek breakthroughs, and has always been concerned and valued by the exploration departments of major oil companies. According to statistics, at present, the oil resources in my country's piedmont zone are about 7.868 billion tons, 1.996 billion tons have been proven, and the proven rate is 25%; natural gas resources are about 10.98 trillion cubic meters, 1.1 trillion cubic meters have been proven, and the proven rate 11%. It can be seen from the perspective of the scale of remaining resources that the proven rate of resources in the piedmont zone in my country is low, and the potential for oil and gas exploration is huge. [0003] The zoning of piedmont thrust structure can be divided into thick be...
