Abstract
Extended horizontal well drilling technology drilling technology represents one of the world peak is a very complex technology. Reach horizontal wells currently drilling the important and difficult research focused on the friction / torque,track design,directional control several aspects of the problem is the string of friction torque reach horizontal well technology one of the core issues,It decided to extend the maximum horizontal displacement. The horizontal extension of the ability is better,then the higher the output of single well. Therefore,the extension of horizontal well influences the level of output. Through from the collection,analysis data from horizontal wells to start at home and abroad,according to the characteristics of large displacement horizontal well,using the friction / torque test model,analysis and forecasting of different hole sizes,different depths,under different conditions wellhead hook load and torque evaluation of the horizontal displacement of large horizontal extension of the displacement capacity of the key factors,to lower the friction torque of technical measures.
