| Abstract: | The hollow sucker rod used in surface-driven screw pumpwells has the problem of breaking and thread-off. Therefore anew thread-off proof hollow sucker rod is developed. Thestructure and operating principle of the new rod are expounded,and its technical characteristics are commented. Field useshows that the new rod has preferable tensile and torsioncapability and higher adaptability in deviated holes comparedwith other hollow sucker rods. |
