CLUSTER WELL BOREHOLE OBSTACLE AVOIDANCE PATH DETERMINATION METHOD AND APPARATUS

The present invention relates to the field of petroleum drilling engineering, and provided thereby are a cluster well borehole obstacle avoidance path determination method and apparatus. The method comprises: acquiring an anti-collision scanning result of a current well borehole on a first horizontal cross-section; according to the anti-collision scanning result of the current well borehole on the first horizontal cross-section, determining the position and an error ellipsoid of each adjacent well borehole of the current well on the first horizontal cross-section; according to the position and the error ellipsoid of each adjacent well borehole of the current well on the first horizontal cross-section, determining an obstacle area of each adjacent well borehole of the current well; connecting projections of the current well borehole and a current well target point in a straight line on the first horizontal cross-section; and if the connected line segment does not intersect with the obstacle areas, determining
