The invention discloses a shale oil horizontal well track design and on-site tracking adjustment research method. The method comprises shale oil sweet spot identification and evaluation, horizontal well optimization and track design and shale oil horizontal well on-site tracking adjustment. A 'four-optimal-two-precision' method formed by the shale oil horizontal well track design and on-site tracking adjustment research method lays a foundation for realizing integration of high and stable yield of shale oil in a blocked lake basin and production and storage increase. A set of technical methodis provided for carrying out horizontal well position optimization design research and drilling well dynamic tracking analysis in a shale oil development area, and the method has great reference and popularization significance. 本发明公开了一种页岩油水平井轨迹设计与现场跟踪调整研究方法，包括页岩油甜点识别与评价、水平井优选与轨迹设计、页岩油水平井现场跟踪调整。本发明页岩油水平井轨迹设计与现场跟踪调整研究方法形成的"四优-二精"做法为实现闭塞湖盆页岩油高产稳产，建产增储一体化奠定基础。对在页岩油发育区开展水平井位优选设计研究及钻井动态跟踪分析提供了一套技术方法，具有较大借鉴和推广意义。
