复杂地质构造速度模型插值方法研究

Study on velocity model interpolation method of complex structure

离散数据网格化不仅是数据处理的核心技术,同时也是科学可视化的前提,插值法是函数逼近的一种方法,它能将离散的数据结合起来形成一系列连续的函数,并由函数求取其他点的位置,本文对常用的六种空间插值方法进行了研究。并选择较适合插值方法对复杂构造的地震勘探数据进行插值方法处理,画出二维可视化图,图中以不同的形态解释地下复杂构造的空间分布情况,并对各种插值方法进行分析,找出最适合复杂构造的插值方法。

Discrete data grid not only is the core of data processing technology, and is also the premise of scientific visualization. the interpolation method is a kind of function approximation method, it can combine discrete data to form a series of continuous function, and the function to calculate the position of the other points, in this paper, the commonly used six space difference method are studied, mainly analysis the characteristics of various methods, And select suitable for interpolation method for complex structure seismic exploration data interpolation method processing, draw 2 d visualization, explain complex underground structure in different form in the figure of space distribution, and to analyze various interpolation method, and find out the most suitable interpolation method of complex structure.
