| Abstract: | The stress applied on casing strings in well bore fitted with centralizer and without centralizer is analyzed. A calculation model for frictional drag of casing strings in an extended reach well is deduced. Some programs based on the model with visual basic language are given. This model can be used to predict the frictional drag and hook load of running completion casing. The application of the program in the Ping 1 well with a horizontal displacement over 3000 meters on land oilfield in China shows that the calculated results agree with the measured data. |
