摘要
为了更准确地测试高温注汽井的地层温度、压力数据,研制了一种高温注汽井温度压力测试仪。该仪器由井下仪器与地面处理两个部分组成:井下仪器以PIC16F883单片机为核心,完成井内温度、压力、磁定位的采集和存储;地面处理实现井下数据的回放与处理。介绍了该仪器的结构和主要技术指标、系统的硬件及软件设计。应用情况表明,该仪器能够满足高温注汽井的测试要求。
In order to more accurately test of high temperature gas injector formation temperature and pressure data , a high temperature double parameter tester is developed .The instrument was composed of downhole instruments and ground processing： the downhole instrument completed the borehole temperature, pressure, CCL of the collection and storage with PIC16F883 MCU as the core; Ground processing achieved downhole data playback and processing .This article introduces the structure of the instrument and the main technical indicators , the system hardware and software design .Application shows that the instrument can meet the testing requirements of the high temperature gas injector .
