浅析油井超导热洗工艺技术改进及应用

Analysis on the Technology Improvement and Application of Superhero Heat Washing Technology in Oil Well

合水油田生产开发过程中,大部分油井存在油稠、含蜡高、凝固点高的特点,易导致抽油机载荷上升,冲程损失增大,泵效降低,严重时会造成杆断、蜡卡等躺井事故。针对这一状况,引进了超导热洗工艺,并将其广泛应用于井筒清蜡工作,形成了一套"超导热洗选井原则及不同井况热洗方法",为油井正常生产提供有利的保障。

In the process of production and development of Hetian Oilfield, most of the oil wells have the characteristics of thick oil, high wax and high freezing point, which can lead to the increase of the load of the pumping unit, the increase of the stroke loss and the decrease of the pump efficiency.Lying accident.In view of this situation, the introduction of superconducting hot washing process, and its widely used in the wellhead waxing work, forming a ＂superconducting hot wash well selection principle and different well state hot wash method＂ for the normal production of oil wells Favorable protection.
