"Well Control Equipment" discusses in detail the functions and technical specifications of well control special equipment-various wellhead blowout preventers, control devices, choke and kill manifolds, blowout preventers in drilling tools, drilling fluid gas separators and automatic drilling fluid injection devices, and introduces the installation, pressure test and daily inspection of the equipment. For those well control facilities with dual "identities", such as weighted drilling fluid devices and mud tank level monitors, well control equipment will not be introduced. In view of the fact that most of the blowout preventers and their control devices used in onshore drilling in China are made in China, and the domestic standard choke and kill manifolds are becoming more and more popular, the well control equipment is mainly made in China. "Well Control Equipment" is a special training textbook for drilling engineers to obtain well control operation certificates, and can also be used as a reference book for teachers and students of related majors in petroleum colleges.
