Method and device for acquiring temperature compensation coefficient of well deviation

The embodiment of the invention discloses a method and device for obtaining the temperature compensation coefficient of well deviation, and the method comprises the following steps: S1, obtaining a detector of which the deformation amount is less than 3% under different temperature conditions; s2, the detector is fixed, and the preset well deviation of the detector is obtained; s3, the environment temperature of the detector is adjusted, and the actual well deviation measured by the detector at different temperatures and the error of the actual well deviation relative to the preset well deviation are obtained; and S4, according to the temperature, the actual well deviation and the error, polynomial curve fitting is adopted, and the temperature compensation coefficient of the well deviation is obtained. The temperature compensation coefficient of the well deviation is obtained through the steps, the temperature compensation coefficient of the well deviation is substituted into a well deviation calculation form
