Marine gas hydrate three-phase dynamic virtual construction method

Abstract

The invention provides a marine gas hydrate three-phase dynamic virtual construction method. According to the method, a view angle is interactively positioned by eyeball tracking, the position of an observation point is acquired by three-dimensional space geometric analysis, the pressure value and the temperature value of the observation point are acquired according to a depth pressure conversionand marine temperature field model, the physical state of a gas hydrate at the position of the observation point is judged according to a gas hydrate three-phase state judgment model built according to geothermal gradient, water temperature gradient, deep sea gas hydrate phase equilibrium curves and the like, the physical state is dynamically displayed in a three-dimensional scene, and eyeball tracking driven gas hydrate three-phase state dynamic simulation effects are achieved. Marine gas hydrate three-phase conversion virtual construction and expression are achieved, so that the stabilizingmechanism of the marine gas hydrate is visually and vividly expressed, gas hydrate three-phase virtual scenes of different sea areas can be built based on the method, and the method is widely used forthe fields of marine gas hydrate laboratory test analysis research, on-site mining simulation, teaching, popularization of science and the like.

Description

technical field [0001] The invention belongs to the technical field of dynamic virtual scene construction of marine natural gas hydrate stabilization mechanism, and specifically relates to a three-phase dynamic virtual construction method of marine natural gas hydrate. The virtualization technology realizes the dynamic construction of a three-phase marine natural gas hydrate scene. Background technique [0002] Natural gas hydrate resources have the characteristics of wide distribution and high energy density. It is a potential energy source and a metastable energy source. For example, marine natural gas hydrate can be expressed as solid, liquid, and gas under different pressures and temperatures in the deep sea. Its phase transition directly restricts the maximum depth and the thickness of the ore layer where gas hydrate is formed, and it is also the main reason for the difficulty in mining gas hydrate. By using virtual reality technology to simulate the natural gas hydrate...
