摘要： In a conductor cable for seismic exploration, where the cable will have very high resistance transducers connected to it for transmitting signals from one or more transducer stations to a recording station, there is a controllably conductive path connected across the transducers. The path is only conductive at a voltage greater than the maximum of the signals. And, a constant current source is applied at the recording station. Also, a voltmeter is employed to measure the continuity of the cable.

摘要： A co-variance microwave water cut monitor includes a test cell having a petroleum stress flowing through it while permitting the microwave energy to enter the test cell. A microwave source provides microwave energy to a circulator which in turn provides the microwave energy to an antenna. The antenna provides the petroleum stream in the test cell with the microwave energy and receives reflected microwave energy back from the stream. The reflected microwave energy is provided by the antenna to the circulator which in turn provides the reflected microwave energy as test microwave energy. A detector assembly connected to the circulator detects the intensity of the test microwave energy and provides a corresponding intensity signal. Indicator apparatus connected to the circulator to the microwave source and to the detector assembly provides an indication of the water cut of the petroleum stream in accordance with the intensity signal and the phase difference between the source provided microwave energy and the test microwave energy.

摘要： The watercut of fluid in a mulitphase flow is measured. Microwave energy in the 10 Ghz range is transmitted through a test call having flow passing therein through a known geometry. Attenuation and phase shift of the microwave energy is measured and used to derive the wave number of the microwaves in the unknown fluid. The water fraction of the unknown fluid is then determined from the wave number and the known geometry of the test all using Hannai's equation.

摘要： In a three phase fluid stream microwave monitor, an improved test cell having a fluid stream flowing through it with spaced, aligned first and second antenna located within the test cell to receive microwave energy, irradiate the fluid stream, and receive the microwave energy which has passed through the fluid stream. The test cell has a rotatable cage mounted to form a cylinder enclosing the antennas for reducing an amount of debris in a portion of the petroleum stream flowing therebetween. The cage includes vanes which cause it to rotate, under the influence of the flowing stream to thereby be self-cleaning. The cage also carries a block which lies between the antenna and perpendicular to the axis thereof. Rotation of the cage causes rotation of this block to modulate the microwave transmission in a manner indicative of the fluid velocity.

摘要： A petroleum stream microwave water cut monitor includes test cell means which contains a reference petroleum multiphase fluid sample and which has a sample stream of a petroleum stream passing through it. The test cell is maintained at a predetermined temperature. A source provides microwave energy to one of a first pair of antennae which provides the petroleum stream flowing in the test cell or the reference sample in the test cell with microwave energy. One of a second pair of antennae receives the microwave energy that has passed through either the petroleum stream or the reference sample. A detector detects the received microwave energy and provides a signal corresponding thereto. An indicator provides an indication of the water cut of the petroleum stream in accordance with the received signal power and a phase difference between the source provided microwave energy and the received microwave energy.
