bubble flow泡流一种流动状态,在这种状态下,近似均匀分布和大小比较一致的气泡或油滴以恒定的速率向上流过油或水。相对速度主要取决于较轻相和较重相之间的密度差以及较重相的粘度。 bubble-point pressure饱和压力气体开始从溶液中逸出时的压力。 bucking electrodes屏蔽电极屏蔽电流电极。侧向测井类型电阻率测量系统中的电流电极,屏蔽电流从中流出以约束主电流成为薄的水平电流层。该电极除了在外形上通常是环状或点状(例如钮扣状)之外,其用途如同另一种屏蔽电极(guard
bubble flow A flow condition in which bubbles or droplets of approximately uniform distribution and relatively uniform size flow upward through the oil or water at a constant rate. The relative speed depends mainly on the density difference between the lighter and the heavier phases and the viscosity of the heavier phase. bubble-point pressure The pressure at which gas begins to escape from the solution. bucking electrodes shield electrode shield current electrode. Lateral Logging Type Resistivity measures the current electrode in a system from which a shield current flows to constrain the main current to a thin horizontal current layer. In addition to being generally ring-shaped or punctate (eg, button-shaped) in appearance, the electrode serves the purpose of another guard electrode
