Abstract
The utility model discloses a torque sensor for petroleum logging wireless transmission. The head of an output terminal of the electric torque sensor is electrically connected with a magnetic induction coil, the magnetic induction coil is wound on a magnetic inductor, and the output end of the magnetic induction coil is connected with a signal processing circuit. By means of magnetic induction, an enhanced signal can be induced by using a low power supply level. The power consumption of the sensor is reduced. When a 6V voltage supplies power to the sensor, the power consumption of the sensor can be reduced; and the sensor has small volume and is convenient for logging operation. The power consumption is greatly reduced. A 6V direct-current power supply can fully meet the power requirement of the sensor.
Description
Technical field
The utility model relates to wireless transmission sensing probe in a kind of petroleum engineering mud logging operation, relates in particular to wireless transmission torque sensor in a kind of petroleum engineering mud logging operation.
Background technology
Petroleum engineering well logging technology is the most basic technology in the oil-gas exploration and development activity, is to find hydrocarbon-bearing pool, estimate timely, the most direct means of hydrocarbon-bearing pool, has that the subsurface information of obtaining is timely, various, analysis interpretation characteristics efficiently.At present, utilize electric torque sensor that the drilling well moment of torsion is surveyed collection in the petroleum engineering well logging technology.The electricity torque sensor is according to electromagnetic induction principle work, and the core devices of electric torque sensor is an inductive coil, induces the marking current that can directly measure according to the magnetic field size around the conductor of electrical current by inductive coil.The change in torque that reflects rotary tray motor by the size of current in the measurement electrical conductor.The indentation, there of inductive coil is a Hall element.Two extension lines of Hall element link to each other with the differential input end of operational amplifier by two resistance of R2, R3, the output of operational amplifier links to each other with the base stage of triode Q1, Q2, operational amplifier amplifies the current signal that Hall element induces, be used to drive the base stage of triode Q1, Q2, just the base signal with triode amplifies.One end of inductive coil is by resistance R 1 ground connection, and the other end links to each other in the emitter of triode Q1, Q2, according to the amplification of triode, inductive coil is induced marking current amplify output, the stability of enhancing signal.The defective that prior art exists is: one, the sensor of prior art all designs by general-purpose industrial reference power supply 24V, and the power consumption during work is very big.Two, owing to use 24V industrial standard power supply, cause the sensor overall volume bigger than normal, and need to use numerous inductive probes in petroleum engineering well logging technology, this has just brought inconvenience for the well logging operation.Not being suitable for the nonstandard power supply of the small and exquisite low-voltage of volume powers.
Summary of the invention
The utility model is at the deficiencies in the prior art, provides a kind of and adopt that the nonstandard power supply of low-voltage is powered, overall volume is small and exquisite, makes things convenient for the oil log wireless transmission torque sensor of the wireless operation of well logging.
The utility model is realized by following technical scheme, oil log wireless transmission torque sensor, it is characterized in that, the lead-out terminal termination of electricity torque sensor is electrically connected with magnetic induction coil, described magnetic induction coil is wrapped on the magnetic induction body, magnetic induction coil output termination signal processing circuit.
The beneficial effects of the utility model are, rely on magnetic induction, can induce the signal of an enhancing with low Power Level.Reduce the power consumption of sensor.When 6V voltage is powered to sensor, can reduce the power consumption of sensor, make volume small and exquisite, make things convenient for the well logging operation.Power consumption reduces greatly.The 6V direct supply can fully satisfy its electricity needs.
