%X Based on the existing research results of the project, the integrated application of well trajectory control, extension limit, anti friction and drag reduction tools and technologies is focused on, and landmark and other international general software are used for key design. The drilling technical scheme of 1-2 wells in polar cold sea is formed, and the horizontal displacement of extended reach wells is not less than 12000m. The design contents include: ① trajectory optimization design method based on extension limit: according to the basic information of Sakhalin North vini extended reach well, the trajectory optimization design of sve2 of Sakhalin North vini extended reach well is completed. ② Based on the parameter optimization design method of downhole drag reduction tools, combined with the trajectory optimization design of Sakhalin North vini extended reach well. The parameter optimization design of downhole drag reduction tool sve2 in Sakhalin North vini extended reach well was completed.
