自1900年以来,旋转钻井经历过概念、发展、科学和自动化四个阶段。在这些阶段中,随着钻井工艺的不断发展,各种钻井仪表也随之不断出现和完善。例如,进行喷射钻井,需要控制一系列的水力学及泥浆参数,如泵压、排量、钻头压力降、泥浆粘度、泥浆固相含量及泥浆比重等,平衡钻井需要精细地控制泥浆动液柱压力,否则就实现不了平衡钻井,甚至 Since 1900, rotary drilling has experienced four stages of concept, development, science and automation. In these stages, with the continuous development of drilling technology, a variety of drilling instrumentation will also continue to appear and improve. For example, for jet drilling, a series of hydraulics and mud parameters need to be controlled, such as pump pressure, displacement, bit pressure drop, mud viscosity, mud solids content and mud weight. Balanced drilling requires fine control of the mud column Pressure, otherwise you can not achieve balanced drilling, even
