摘要
深海钻探泥浆举升系统在无隔水管泥浆循环钻井(RMR)工艺中具有关键作用.为了提升举升系统的安全余量和适应性,本文对多泵串并联机制进行了深入研究,详细描述了泥浆举升泵的串并联结构设计和工作原理,探讨了串联和并联运行时流量与扬程的关系以及泵组串并联工况点的数解法和图解法步骤.进一步地,利用模型泵实测特性曲线,使用图解法获取了双泵串并联工况下的Q-H特性曲线和工况点,并提出了双泵协同控制的建议.
Abstract
The deep sea mud lifting system plays a critical role in the Riserless Mud Recovery(RMR)drilling process.In order to enhance the safety redundancy and adaptability of the lifting system,in-depth research on the multi pumps series parallel mechanism was conducted,including the detailed study of the series parallel structure design and working principle of the mud lifting pump,and the relationship between flow rate and lift during series and parallel operation,as well as the mathematical method and graphical method for series parallel operating points of the pump group.Furthermore,by utilizing the measured characteristic curve of the model pump,the Q-H characteristic curve and operating points of the dual pumps series parallel operation were obtained using graphical method.Finally,suggestions for dual pumps collaborative control were proposed.
