The embodiment of the invention discloses a sector measurement data
correction method based on a borehole
diameter measuring instrument, and relates to the technical field of the
petroleum logging. The method comprises the following steps: measuring standard data of sleeves in different sizes through the borehole
diameter measuring instrument; obtaining scale coefficients corresponding to the sleeves in different sizes by using a
scale measurement method; obtaining a
linear measurement formula according to the standard data and scale coefficients of the sleeves in different sizes; measuring the actual measurement data of the borehole
diameter through the borehole
measuring instrument; and correcting the actual measurement data according to the
linear measurement formula. The problems thatthe influence on the measurement result is large and the correction cannot be performed when the borehole measuring instrument is eccentric in the prior art can be solved.
