Abstract: Domestic rectangle tank has the problem of poor agitating performance and it's difficult to clean the sand. In connection with these problems, the Petroleum Machinery Factory of CNPC Bohai Equipment Manufacturing Co., Ltd. has developed a new type cylinder solid control system by reasonable design. The fine structure can reach the best agitating purpose, and realize full drilling fluid suction and full liquid waste discharging. This paper introduced the configuration, structure, technical parameters, test and applications of the system. This system has simple structure and scientific process. It has obvious effect on improving the drilling fluid performance and reducing environmental pollution. It's the development trend of drilling liquid solid control system.

Key words: cylinder tank, drilling liquid, solid control system

摘要： 针对矩形罐固控系统搅拌性能差、清砂困难等问题,中国石油渤海石油装备制造有限公司石油机械厂通过合理的结构设计,研制了一种新型的圆形罐固控系统,可使钻井液达到最佳的搅拌效果,实现100%钻井液吸入、100%废液排放。文章介绍了圆形罐钻井液固控系统的配置、结构、技术参数、试验与应用情况。该系统结构简单、工艺流程科学,对于保持和提高钻井液性能、减少环境污染具有明显的效果。圆形罐固控系统是钻井液固控系统一种新的发展趋势,具有极好的推广应用前景。
