IADC钻井手册第12版的这一早期版本章节解释了液压系统如何影响钻井过程。©空间碎片协委会。版权所有。这本新电子书讨论了“液压”这一广义术语所涵盖的内容，并简要介绍了液压相关设备。包括密度、粘度、屈服点、流变模型、流速和流体速度等水力参数。讨论了双联泵和三联泵的速度和循环率测定。水力学的应用，包括估计井底压力和井筒压力管理，以及环空速度。 五色插图和图表。8页，包括索引。

This early-release chapter of the 12th edition of the IADC Drilling Manual, explains how hydraulics impact the drilling process. ©IADC. All rights reserved.The new eBook discusses what is covered by the broad term "hydraulics", as well as briefly describing hydraulic-related equipment. Hydraulic parameters, such as density, viscosity, yield point, rheology models, flow rate and fluid velocity are covered. Velocity and circulation rate determinations for both duplex and triplex pumps are discussed. Applications of hydraulics, including estimating bottomhole pressure and wellbore pressure management are covered, as is annular velocity. Five color illustrations and charts. 8 pages, including index.
