石油压裂液混配车自控系统的设计与应用

摘要

针对某油田在石油压裂液控制中所面临的问题，基于 OMRON C200HS 开发了一套石油压裂液混配车自控系统。介绍了自控系统的工作原理、硬件组成、软件流程及其所实现的功能。现场试验与实际应用表明：该自控系统可以按照生产需要快速配置不同比例的石油压裂液，橇出口粘度达到试验最高粘度的86％以上，大幅提高了配液质量并减少了胶粉浪费。%Considering the matters which bother the control over the petroleum fracturing fluid and basing on OMRON C200HS,a mixing car’s auto-control system was developed,including the introduction of its working principle,hardware structure and software implementation as well as the realized functions.Field test and ap-plication results show that this auto-control system can meet requirements for the petroleum fracturing fluid do-sing,and it can make the fracturing fluid viscosity exceed 86% of the highest viscosity along with an improved dosing quality and saved glue powder.
