摘要
为获取油气井下的关键参数,设计了一套井下智能监测系统.系统以PIC18F67K22 作为主控芯片,集成温度、压力、位移、含水率、加速度传感器 5 种监测模块及电源模块.同时制定通信协议、配置相关参数并采用QT creator开发上位机,搭建了上位机与采集系统之间的完整通信体系,实现了多参数实时采集监测.通过模拟高温高压多参数变化实验、测试环境实时变化曲线,验证了监测系统的实时性、稳定性、准确性,结果表明该系统可满足实际需求,为油气井工具智能化提供了可靠方案.
Abstract
A downhole intelligent monitoring system was designed to obtain the key parameters of oil and gas wells.The sys-tem used PIC18F67K22 as the main control chip and integrated five monitoring modules including temperature,pressure,dis-placement,water content,acceleration sensor,and power module.At the same time,the communication protocol was formulated,the relevant parameters were configured,and QT creator was used to develop the upper computer,which built a complete commu-nication system between the host computer and the acquisition system,and the real-time multi-parameter acquisition and monito-ring was realized.By simulating high temperature and high-pressure multi-parameter change experiments and testing environment real-time change curve,the real-time,stability and accuracy of the monitoring system were verified,and the results indicate that it can meet the actual needs,providing a reliable solution for the intellectualization of oil and gas well tools.
