  • Method for self-adaptive survey calculation of wellbore trajectory
    Patent number: 11319796
    Abstract: The disclosure relates to a method for self-adaptive survey calculation of a wellbore trajectory in oil drilling, and belongs to the field of oil and gas drilling technologies. Curve characteristics of a calculated survey interval are identified by calculating measurement parameters of four survey stations corresponding to the survey interval and two survey intervals before and after the survey interval, so that an appropriate curve is selected to calculate a coordinate increment of the survey interval, then parameters of the curve characteristics which are close to the shape of the calculated wellbore trajectory are selected automatically, and the curve type which is closest to an actual wellbore trajectory is fitted automatically and the survey calculation is carried out.
