摘要： A well logging system and method for determining the water saturation of an earth formation and the resistivity of the water using complex dielectric constant and formation porosity measurements. Electromagnetic energy is transmitted into the earth formation from a borehole at a frequency lying within the range of frequencies from 10 MHz to 200 MHz. Electromagnetic energies are received at two locations in the borehole. A complex dielectric constant is derived from the received electromagnetic energies. The water resistivity and the water saturation of the earth formation is derived in accordance with the porosity of the earth formation and with the real and imaginary parts of the derived complex dielectric constant.

摘要： The present invention is a well logging method for determining the water saturation of an earth formation and the water's resistivity. Electromagnetic energy is transmitted into the earthen formation from a borehole traversing the earth formation. The electromagnetic energy is transmitted at two different frequencies within a range of frequency from 10 MHz to 200 MHz. Electromagnetic energies are received in the borehole from the earth formation. A phase difference and amplitude ratio for each transmitting frequency is derived from the received electromagnetic energy. The water resistivity and water saturation of the earth formation are derived from the derived phase differences and the amplitude ratios.

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： A dielectric well logging system is provided to determine dielectric constant and resistivity in formations invaded by water to determine oil and water saturations of the formations. Plural transmitters are activated in a time division multiplex manner and sensed by receiver coils.

摘要： A well logging system and method of the present invention determines the dielectric constant and/or conductivity of earth formations some of which have fluid invasion. The system and method of the present invention include the transmission of electromagnetic energy into the earth formations from a first location in a borehole in the formations at a frequency which enables the electromagnetic energy to propagate throughout the surrounding earth formations. Electromagnetic energy is received by receivers at three locations in the borehole which are spaced longitudinally from the location of the transmission of the electromagnetic energy. The receivers provide signals representative of the received electromagnetic energy. The dielectric constant and/or resistivity of the earth formations are determined in accordance with the signals from the three receivers.

摘要： An odometer that employs a pulse generator, the pulses of which correspond to a given increment of linear distance. It has a correction circuit which may be set to either add or subtract a pulse after a predetermined number of pulses have been counted. This corrects the linear distance measured for any cumulated total. Consequently, inaccuracies in the dimension represented by each pulse will be periodically compensated for by the added or deleted pulse.

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.
