摘要： Apparatus for determining the dielectric constant and/or resistivity of earth formations traversed by a borehole includes a transmitter which transmits electromagnetic energy into the earth formation from a first location in the borehole at a frequency which enables the electromagnetic energy to propagate throughout the surrounding earth formations. Receivers receive electromagnetic energy at two locations in the borehole which are spaced longitudinally from the transmitter provide signals representative of the total electromagnetic fields at the receiver locations. Circuitry determines the dielectric constant and/or resistivity of the formations in accordance with a secondary field ratio and a phase difference derived from the signals provided by the receivers.

摘要： Oil well production is often measured by using a settling tank, pump, flowmeter and a water-cut meter. Fluid from a well being tested is allowed to accumulate in the settling tank and, after a predetermined settling time, is pumped through the flowmeter and water-cut meter for gauging. The present invention is an improved water-cut meter which first determines the impedance of the free water pumped from the tank and later determines the impedance of the oil/water emulsion emerging from the tank. The ratio of the emulsion impedance to the free water impedance is proportional to percent water-cut of the fluid during the water-continuous phase. When the emulsion switches to oil-continuous phase, the system utilizes probe impedance for the water-cut determination. Using standard techniques, the water-cut and flow rate signals are then combined to calculate the total oil and water content of the settling tank fluid.

摘要： The present invention is a water cut monitor which includes a settling tank in which a quantity of fluid from a producing well is accumulated. The fluid is removed as a stream of fluid after a predetermined interval from the accumulation of the fluid by the settling tank so as to allow the accumulated fluid to separate into three phases: free water, water-continuous and oil-continuous. The flow rate of the stream of fluid is measured and a corresponding flow rate signal is provided as well as a temperature signal corresponding to a sensed temperature of the stream of fluid. The water cut monitor includes a plurality of electrodes in contact with the fluid. Injection electronics connected to at least one of the electrodes provides an injection voltage and injection current to the fluid stream and also provides signals corresponding to the injection voltage and injection current. A voltage in the fluid stream is measured and a measurement signal provided. A computer determines the water cut of the petroleum stream in accordance with the temperature signal, the injection voltage and injection current signals, the electrical phase angle signal and the measured voltage signal.
