| 摘要 | A measurement assembly for determining an electrical resistance of a fluid in a wellbore is provided. The measurement assembly can include a non-conductive frame, comprising an excitation electrode and a monitoring electrode coupled to the non-conductive frame. The measurement assembly can also include a central electrode in a flow path for the fluid, wherein the flow path is defined by the non-conductive frame. The central electrode can be positioned for conductively coupling the excitation electrode and the monitoring electrode through a conductive path defined by the fluid. Further, the measurement assembly can include a power source for transmitting power to the excitation electrode for determining the electrical resistance of the fluid. The electrical resistance of the fluid can be used to determine whether the fluid includes oil, water, or gas. | ||||||
