1、 摘 要 在油井开采过程中，需要对油井的温度、压力、动液面等参数进行不定期测 量以监控采油过程，其中动液面是一个重要的参数。传统的动液面测量方法由人 工操作、人工信号判读。其数据计算整理工作繁琐，误差大、自动化程度低、效 率低。本文分析了传统动液面测量并与新型的动液面测量系统进行对比，研究了 动液面测量的详细步骤。并以 STC89C52 单片机为核心设计超声波测距的硬件电 路和软件来模拟动液面检测系统。首先设计了系统的整体方案，整个电路采用模 块化设计，包括控制模块、数据采集模块、显示等模块等，软件由主程序、预置 子程序、发射子程序、接收子程序、显示子程序等组成。最后对系统进行调试， 实现了测

3、tion and artificial signal interpretation. Data collation and calculation are complicated with big error, low degree of automation and low efficiency. This paper analyzes the traditional working level measurement compared to the new measurement system, and studies the working level measurement detai
4、led steps. The hardware and software of the ultrasonic range is designed based on STC89C52 to simulate the working level detection system. First, the overall scheme of the system is designed with module design method, including control module, data acquisition module, display module etc. The software consists of main program, preset subroutine, launched subroutine, receive subroutine. display subroutine and so on. Finally, debugging the system and the system implements the functions of ranging
