| Abstract: | The causes for failure of sucker rod string on a surface driven single screw pump system are analyzed, including small safety coefficient of rod string, low rigidity, being stuck by sand and gum deposits of high viscosity crude, improper overload protection and unqualified material. Measures for preventing rod string failure are improving the overload protection system, designing rod string with rational parameters, checking the rigidity and verifying the quality of rod string. |
