The invention provides a dual power switching system and a while-drilling gyro inclination measurement device having the same. The dual power switching system comprises a power input unit and a monitoring unit, wherein the power input unit comprises a first power source and a second power source; the monitoring unit is used for monitoring voltages of the first power source and the second power source, and the monitoring unit is optionally connected to the first power source or the second power source according to the voltages of the first power source and the second power source; when the voltage of the first power source is greater than a set threshold value and the voltage of the second power source is less than or equal to the set threshold value within a preset time, the monitoring unit is connected with the first power source; and when the voltage of the second power source is greater than the set threshold value within a preset time, the monitoring unit is connected with the second power source. By applying the dual power switching system and the while-drilling gyro inclination measurement device having the same, the technical problem that a while-drilling gyro inclination measurement device is difficult to operate underground for a long time in the prior art can be solved.
Description
technical field [0001] The invention relates to the technical field of petroleum drilling, in particular to a dual power supply switching system and a gyro inclinometer while drilling with the same. Background technique [0002] The gyro inclinometer while drilling system is mainly used to measure well inclination, azimuth, etc. in oil drilling operations, and its main power supply is generally a battery or a generator. Compared with the conventional inclinometer while drilling gyro system, it is not affected by magnetic interference, can work in a magnetic environment, and has a wide range of applications, but its load power consumption is large. If a battery is used as its main power supply, the It is difficult for the instrument to work downhole for a long time, which will inevitably lead to an increase in the number of trips, which will bring great risks to oil drilling operations and greatly increase the cost of drilling. The power cannot be cut off during the process,...
