Beschreibung
Zusammenfassung:	The invention relates to a target evaluation method and system in horizontal well landing, and belongs to the technical field of petroleum and gas drilling. According to the invention, the target precision in the A target spot is considered; the target in horizontal well landing is evaluated by integrating the target precision in the A target spot and the well deviation azimuth coincidence rate, so that the evaluation result of the target in horizontal well landing is more comprehensive and scientific, the evaluation of the target precision in landing by petroleum companies and directional construction units is facilitated, and the borehole trajectory quality is improved. 本发明涉及一种水平井着陆中靶评价方法及系统，属于石油天然气钻井技术领域。本发明在考虑A靶点中靶精度的基础上，增加了井斜方位角符合率，综合A靶点中靶精度和井斜方位角符合率来对水平井着陆中靶进行评价，使水平井着陆中靶评价结果更加全面、科学，便于石油公司和定向施工单位评价着陆中靶精度，提高井眼轨迹质量。
