%K Extended reach well;mechanical extension limit
%X In 2018, the theoretical derivation and MATLAB software were used to model the extended reach well extension limit in Beijing, and the program was compiled to finally form the mechanical extension limit Atlas of extended reach well under different conditions. The main contents of the chart are as follows: 1) trajectory control and anti friction and drag reduction technology for extended reach wells, mainly including: trajectory optimization control model with minimum friction; Calculation model of mechanical extension limit of extended reach well; ② According to the analysis, under the given conditions of relevant drilling parameters, the hole extension length is limited. In order to improve the hole extension length, the prediction chart puts forward the corresponding control measures to increase the extension limit from the aspects of drilling rig performance.
