Abstract
The invention discloses a method for demagnetizing wires inside a sensor for a wireless inclinometer while drilling. The power lines are twisted uniformly, and the signal lines are twisted uniformly. The method is suitable for the manufacturing process of the underground wireless inclinometer probe during the operation of the directional well, can effectively reduce the cost, improve the stability and the precision of the probe and reduce the complexity of drilling accidents.
Description
Technical field
The present invention relates to sensor internal cabling demagnetization method, especially a kind of oil drilling industry underground equipment of the present invention
The sensor internal cabling demagnetization method of wireless drilling inclinometers.
Background technology
Gravity, Magnetic Measurement sensor are the instruments being measured wellbore parameters by three-dimensional accelerometer and fluxgate.
Wherein magnetic azimuth is that the parameter measured by accelerometer and fluxgate carries out calculated, the accurate measurement of this parameter
Depending on stablizing of magnetic field environment, if now fluxgate is by extraneous magnetic disturbance, the data of measurement will be by the biggest
Impact.
Gravity, Magnetic Measurement sensor need the instrument by sensor is its underpart to power, now when LWD instrument
Electric current conference reach 1.5 2A.A bigger magnetic field can be formed near electric wire in the case of this electric current, if magnetic flux
Door will be greatly affected by magnetic field data measured by electric current, badly influences the accuracy of measurement.
Summary of the invention
The technical problem to be solved is to provide and a kind of eliminates the magnetic disturbance that cabling brings to fluxgate, design
Simply, the sensor internal cabling demagnetization method of quick, safe wireless drilling inclinometers is operated.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is: the biography of a kind of wireless drilling inclinometers
The internal cabling demagnetization method of sensor, by passing sensor after the positive wire of power supply and the ground wire multiple twin of power supply, will send signal
Holding wire and after receiving the holding wire multiple twin of signal through sensor.
Uniform multiple twin wanted by described power line, and holding wire wants uniform multiple twin.
The invention has the beneficial effects as follows: downhole wireless directional tool inserting tube manufacture process be applicable to directional well operation,
Cost can be effectively reduced, improve the stability of inserting tube, precision, reduce drilling failure complicated.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is described in further detail:
The operation principle of the sensor of the wireless drilling inclinometers of the present invention and prior art are identical, are referred to
Prior art, so no longer describing, the present invention is that sensor internal Wiring method is different from the difference of prior art, enters below
Row detailed description:
The sensor internal cabling demagnetization method of wireless drilling inclinometers of the present invention, by positive wire and the power supply of power supply
Ground wire multiple twin after through sensor, through sensor after the holding wire of signal being sent and receives the holding wire multiple twin of signal.
Uniform multiple twin wanted by described power line, and holding wire wants uniform multiple twin.
Sensor will be passed after the ground wire multiple twin of positive source wire and power supply, the holding wire of signal will be sent and receive letter
Number holding wire multiple twin after through sensor.Due to two wire multiple twins side by side, they electric currents each other are equal, in opposite direction,
Produced magnetic field is also contrary, thus cancels each other out.Twisted-pair feeder must uniformly, as long as ensure uniformly its when big electric current passes through also
Will not be to magnetic fields.
In sum, present disclosure is not limited in the above embodiments, and the knowledgeable people in same area can
Can propose other embodiment within technological guidance's thought of the present invention easily, but this embodiment is included in this
Within the scope of bright.
Claims (2)
1. the sensor internal cabling demagnetization method of a wireless drilling inclinometers, it is characterised in that the positive pole of power supply is led
