Abstract
The utility model relates to a measuring instrument for oil well liquid level pressure. In the utility model, a pressure or temperature sensor obtains original signals and sends the original signals to a preamplifier B, the original signals are processed by the preamplifier B and input into the input end of an A/D converter U2 of a pulse code processing circuit C, the A/D converter U2 of the pulse code processing circuit C converts the electrical signals of the preamplifier B into numerical magnitudes which are input into a single chip computer U1 which encodes the numerical magnitudes, and pulse code signals are output and transmitted to two power amplifiers of an echo liquid level detecting instrument by amplification after encoding. The utility model can measure the liquid level depth of an oil well and the pressure and the temperature of the oil well liquid level.
Description
The utility model relates to the oil well liquid level parameter measurement instrument.
At present oil well echo liquid level depth-sounder is made up of microphone, preamplifier, post amplifier, power amplifier, recording pen five parts, and it can only be used for surveying oil-well level, and can not be used for surveying oil temperature, pressure.This instrument when measuring level as long as the recorder paper feed is accurate, the pulse of record is clear and legible, and the oscillating quantity of recording pen is not had required precision, used recording pen is the magneto-electric recording pen, only be suitable for recording pulse signal, and the way of can not the use tricks frequency or the meter width of cloth writes down the measured value of well head pressure and temperature.
The purpose of this utility model is to provide that a kind of well liquid goes out pressure-measuring device, it both can survey the level of oil well, also can survey the pressure or the temperature of oil well liquid level, thereby realizes the pulse code digital record of pressure or measured temperature.
The oil well liquid level pressure-measuring device, comprise echo liquid level depth-sounder D, it is characterized in that at the signal input part of the power amplifier of echo liquid level depth-sounder D and connect pressure or temperature signal detects treatment circuit, pressure or temperature signal detect treatment circuit by pressure or temperature pick up A, preamplifier B and pulse code treatment circuit C form, the signal input part of preamplifier B connects the signal output part of pressure or temperature pick up A, the signal output part of preamplifier B connects the input of the analog-digital converter U2 of pulse code treatment circuit C, the analog-digital converter U2 of pulse code treatment circuit C converts the signal of telecommunication of preamplifier B to numerical quantities, input single-chip microcomputer U1 encodes by U1 logarithm value amount, and coding back output pulse code signal is by amplifying two power amplifiers sending into echo liquid level depth-sounder D respectively.
Advantage of the present utility model is that it both can be used for surveying the level of oil well, also can survey liquid level pressure, the temperature of oil well, and pressure or temperature survey record value can digital direct-reading, the reading intuitive and convenient, and must not carry out the indicating value scale to recording pen; Recorder is not had required precision, reduced the manufacturing cost and the use cost of instrument, and simple to operation.
Accompanying drawing 1 is a main circuit structural representation of the present utility model.
Embodiment:
A selects common pressure or temperature pick up for use, the preamplifier that B adopts echo liquid level depth-sounder to use, and the analog-digital converter U2 of pulse code treatment circuit C selects AD for use
574, single-chip microcomputer U1 selects 8751 for use.Then the signal input part of preamplifier B is connect the signal output part of pressure or temperature pick up A, the signal output part of preamplifier B connects the input of the analog-digital converter U2 of pulse code treatment circuit C, the signal output part of pulse code treatment circuit C is attempted by the two-way of power amplifier.
Operating principle: during work, pressure or temperature pick up A deliver to preamplifier B with the signal that detects, send into pulse code treatment circuit C through preamplifier B amplification, the analog-digital converter U2 of pulse code treatment circuit C with the signal of telecommunication of preamplifier B convert numerical quantities to, input single-chip microcomputer U1 encodes by U1 logarithm value amount, coding back output pulse code signal is sent into power amplifier by amplifying to handle, and connects recording pen and carries out record.
