The invention provides a dual power supply switching system and a gyro inclinometer with the same. The dual power supply switching system includes: a power supply input unit, the power supply input unit includes a first power supply and a second power supply; a monitoring unit, for the monitoring unit For monitoring the voltage of the first power supply and the second power supply, according to the voltage of the first power supply and the second power supply, the monitoring unit can be selectively connected to the first power supply or the second power supply; wherein, when within a preset time, the first power supply The voltage of the second power supply is greater than the set threshold and the voltage of the second power supply is less than or equal to the set threshold, the monitoring unit is connected to the first power supply; when the voltage of the second power supply is greater than the set threshold within the preset time, the monitoring unit is connected to the second power supply connect. The technical scheme of the invention is applied to solve the technical problem that the gyro inclinometer while drilling is difficult to work in the well for a long time in the prior art.
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,...
