Research On Kinematics Simulation And Application For Horizantal Well Tractor

With the horizontal wells,unconventional wells increased year by year,the demand for horizontal well tractor delivery technology has become increasingly urgent.At present,the horizontal well tractor delivery technology is not mature,accidents often occur in oil and gas fields.Therefore,it is urgent to study on the kinematics simulation and field application of the horizontal well tractor.In this paper,the horizontal well tractor is used as the research object,and well tractor is studied in detail from the aspects of the structure,operation mode,kinematics simulation and field application in the horizontal wells of China.Firstly,the internal structure of the horizontal wheeled tractor is studied,and the main object of the simulation study of the horizontal well tractor is determined.The mathematical formula of the tractor is obtained.The above equation can be used to determine the horizontal well tractor under different working conditions.The size of the power required.Secondly,the multi-body dynamics software ADAMS is used to simulate the traction short section,and the simulation and analysis are carried out in a variety of situations.The obstacle process of the horizontal well tractor and the change of the contact force are observed.The tractor power required to cross a certain height of the obstacle.Finally,the paper analyzes the situation of the horizontal well tractor in Xinjiang oil field,and puts forward some suggestions on how to improve the working quality of the current horizontal well tractor,according to the theoretical analysis and simulation of the previous data,Fine control of motor torque and other parameters,you can flexibly control well tractor's forward and obstacle movements,it has certain significance to improve the working quality of the tractor.
