三维观测系统属性分析与优化设计

三维观测系统设计及其属性分析研究是地震数据采集的一个重要环节，其中观测系统属性分析中炮检距分布的合理性又是最重要的参数之一。现有的地震数据采集软件也未提供一个定量分析评判的标准。为此本文从炮检距分布合理性的定量化判断及其观测系统参数的最优化设计出发，提出了采用面元内相邻炮检距的变化率大小来判断炮检距分布的均匀性，利用炮检距变化率的方差最小化作为观测系统参数优化选择的目标函数，这在一定程度和部分环节上为观测系统的优化设计提供了新的方法和手段。

Attributes analysis and optimum design of 3-D geometry.

Attributes analysis and design of 3-D geometry are an important link of seismic data acquisition, among which the reasonableness of offsets distribution in attributes analysis of geometry is one of most important parameters. Common-used seismic data acquisition software don't provide distinguishing standard of quantitative analysis. For that reason,starting from the quantitatively distinguishing standard of offsets-distributing reasonableness and optimum design of geometry parameters , the paper presented that using the size of changing rate of adjacent offsets within a bin to judge the uniqueness of offsets distribution and minimizing the variance of offsets-changing rate for objective function of optimizing geometry parameters, which provided new method and tool for optimum design of geometry to a certain degree and in part links.
