Description

technical field

[0001] The invention belongs to the field of petroleum exploration instruments and equipment, and relates to a wireless inclinometer while drilling, in particular to a wireless inclinometer while drilling for measuring wellbore trajectory during directional drilling. Background technique

[0002] In the process of directional drilling in the petroleum industry, fluxgate inclinometers are often used for construction. This type of inclinometer while drilling uses the Cartesian coordinate system composed of the vertical line of the wellhead and the geomagnetic field as the reference to define the directional parameters, and uses the relationship between the probe coordinate system and the reference coordinate system to measure the directional parameters. There are two types of inclinometers while drilling: wired and wireless.

[0003] The existing wireless inclinometer while drilling uses the fluxgate sensor as the orientation sensor, and converts the geographi...
