%X Based on the existing research results of the project, the focus is on the integrated application of wellbore trajectory control, extension limit, and anti friction and drag reduction tools and technologies. International software such as Landmark is used for key design, forming a drilling technology plan for 1-2 wells in the polar cold sea, with a horizontal displacement of no less than 12000m for large displacement wells. The design content includes: ① Track optimization design method based on extension limit: Based on the basic information of the Sakhalin North Vini large displacement well, the track optimization design of SVe2 for the Sakhalin North Vini large displacement well is completed. ② The parameter optimization design method based on downhole drag reduction tools combined with the trajectory optimization design of Sakhalin North Vinny high displacement well. Complete the parameter optimization design of the downhole drag reduction tool SVe2 for the Sakhalin North Vinny high displacement well.
