持率 meaning in English
holdup
Examples
- Three phase flow water holdup for data inversion by using reservoir saturation tool
用油藏饱和度仪资料反演求解三相流动持率研究 - A recent abc news / washington post poll puts mr bush ' s approval rating at 33 % and his disapproval rating at 65 %
《华盛顿邮报》和美国广播公司日前联合发布的一项民意调查结果显示，布什的支持率为33 % ，而不支持率达到65 % 。 - The measurement of oil / water two - phase flow is primarily accomplished by the combination of total flow rate and holdup measurement , and at present , the rotator flowmeter is used to measure the total flow rate . since the rotator flowmeter has movable parts , which makes its responsibility behave nonlinearly under poor environment of me under hole whose fluids have very complex and changeful characteristics and affects the measurement precision . what ' s more , the widely used centralized measurement instrumentation meets problems in oil wells characterized with high production or high water cuts
通常油水两相流测量主要是通过总流量和持率的测量组合来完成的，目前在总流量的测量中主要使用的是涡轮流量计，由于涡轮流量计具有可动部件使其在流体特性复杂多变的恶劣井条件下的响应呈非线性变化规律，影响测量精度，此外，普遍采用的集流型测试仪器在高产井及含水率高的油井中使用也遇到困难，为此，一种新型的适合非集流型点测的测试方法和测试仪器亟待发展和推广。 - So anew type of measurement and instrumentation is badly needed and developed which is suitable for non - centralized and stationary measurement based on this idea , this study take the new type of oilavater two - phase flow measurement and instrumentation development as the basic goal , cany out some theoretic exploration of measurement in order to improve oil / water two - phase flow well logging method and technique , and try to accomplish bom holdup and total flow rate measurement with one equipment simultaneously so as to push forward development of oilavater two - phase flow well logging
本文正是基于这一思想，以开发新的油水两相流测试仪器为目标，进行先期的测量理论探索，试图从原理上改进油水两相流测井方法和工艺，实现利用同种电学敏感原理同时完成持率和总流量的测量，推动油水两相流测井技术的发展。
