多功能储层饱和度测井仪的数字系统设计

Design of Digital System for a Multi-Function Reservoir-Saturation Logging Tool

介绍一种用于套管井中的多功能储层饱和度测井仪的数字系统设计方案,仪器使用双探测器,双工作模式和多谱数据采集.文中对仪器的组成原理和几个重要的数字控制部件的功能进行了详细分析,对有关重要的设计细节也给予了说明,并给出了主要的数字仿真结果.关键器件采用Lattice的ispLSI1K系列883B级,EDA设计环境为ispLEVEL3.0平台.

The digital system design scheme of a multi-function Reservoir Saturation Tool that used in the casing well is introduced. The instrument uses double detector, double working mode and multi-spectrum acquisition. The paper labors the composing principle and some significant digital control devices, and illuminates some related significant disign details, and it also displays the results of central digital simulation. The used key device is the 883B grade of ispLSI1K series of Lattice corporation. And the EDA design environment is the ispLEVEL3.0 platform.
