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.

摘要： A dual spectra well logging system includes a well logging tool which is adapted to pass through a bore hole in an earth formation. The well logging tool includes at least two sensors which sense at least one condition of the earth formation and provides corresponding pulse signals. A circuit connected to the sensors provides a combined pulse signal wherein the pulses of the pulse signal from one sensor has one polarity and the pulses of the pulse signal from the other sensor has pulses of an opposite polarity. A circuit applies the combined pulse signal to a well logging cable which conducts the combined pulse signal to the surface of the earth formation. Surface apparatus includes a network connected to the cable which provides control signals in accordance with the polarity of the pulses in the combined pulse signal. A network connected to the cable inverts the combined pulse signal and provides a combined pulse signal and an inverted combined pulse signal. A first switching network receiving the combined pulse signal passes the pulses derived from the pulses of the one polarity in acccordance with the control signals to provide a first pulse signal while a second switching network receiving the inverted combined pulse signal passes the pulses derived from the pulses of the opposite polarity in accordance with the control signals to provide a second pulse signal. An output network processes the two pulse signals to provide an indication of the earth's condition in accordance with the processed pulse signals.

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.
