螺杆泵作为一种机械采油举升设备,适用于稠油、含砂、高含气、高含蜡井的开采,体积小、安装方便,低污染、低能耗,具有其它抽油设备所不能替代的优越性。近年来,螺杆泵井在大庆油田得到广泛应用,螺杆泵采油工艺已成为目前继游梁式抽油机和潜油电泵之后的主力的机械举升方式。但是,随着地面驱动螺杆泵采油技术的进一步推广应用,螺杆泵井在喇嘛甸油田的实际生产应用中,抽油杆柱失效的问题较为突出,严重影响了油田持续稳产目标的顺利实现。本文结合自身实际工作情况,通过对螺杆泵井抽油杆柱失效类型的简要分析,提出一些防治措施。
As a mechanical oil lifting equipment, screw pump is suitable for mining heavy oil, sand, high gas content and high wax wells, small size, easy installation, low pollution, low energy consumption, can not be replaced by other pumping equipment The superiority. In recent years, the screw pump well is widely used in Daqing Oilfield. The screw pump production technology has become the main mechanical lifting mode after the beam pumping unit and submersible pump. However, with the further popularization and application of the ground-driven screw pump oil production technology, the screw pump well lamaden oil field in the actual production and application of the sucker rod column failure is more prominent, seriously affecting the oil field continued stable production target smoothly. In this paper, the actual work of their own situation, through the screw pump well sucker rod failure of a brief analysis of the type, put forward some preventive measures.
