Abstract

Abstract: In order to improve the control accuracy of well trajectory and the visualization technology of drilling data, the measurement error source is analyzed based on MWD measurement principle, and the uncertainty calculation of well trajectory is discussed on the basis of ISCWSA error model; the algorithm is analyzed and designed, and the modeling process is given; Using Python as the programming language, the visualization software of well trajectory uncertainty is developed, which realizes the visualization of well trajectory and the visualization analysis of three-dimensional error ellipsoid of well trajectory uncertainty, and can directly see the size of well trajectory error and the trend of well progress; In the artificial island of Jidong Oilfield, the construction of slave well group with minimum anti-collision distance of 2.6 meters was completed. It provides a good theoretical reference for the wellbore anti-collision and wellbore trajectory control.
