天然气水合物勘探泥浆制冷系统温控单元的改进研究

Research on Automation Control Unit of Drilling Fluid Refrigeration System for Natural Gas Hydrate Exploration

摘要:

针对天然气水合物钻井泥浆制冷系统在使用过程中，人为操作不当或某些设备异常造成系统瘫痪及需要人工频繁开关载冷剂循环泵等问题，在原有系统基础上加入智能温控单元。提高了天然气水合物钻井泥浆制冷系统的自动化程度，解决了制冷过程中的重要隐患，以确保泥浆制冷过程正常进行。

Abstract:

According the problems of natural gas hydrates drilling fluid refrigeration system in the using process, such as improper manual operation, system paralysis caused by some abnormal factors of the equipment and frequent manual switching on and off of refrigeration cryogenic medium circulating pump, the intelligent temperature control unit was added based on the original system to improve the automation degree of drilling fluid refrigeration system for natural gas hydrates. The important hidden dangers of the refrigeration process are solved to ensure the normal process of drilling fluid refrigeration.
