塔河油田酸压气举助排工艺技术应用

Application of Output Aid Technique by Gas Lift of Acid and Fracture in Tahe Oilfield.

针对塔河油田油藏地质特征及井筒条件的复杂多样 ,介绍了塔河油田引进使用液氮气举助排工艺 ,确定适合返排工艺 ,解决诱喷、返排力度不够等问题 ,减少残酸液对储层的污染。解决了抽汲机、抽子在稠油井中下放困难的难题 ,提高了作业安全系数及返排力度 ,达到了诱喷的目的。

To reservoir's geologic property and bore hole complexity in Tahe oilfield,the paper introduces the imported technology of output aid technique by gas lift which is not only solves problems of induced flow and incapacity of output power and decreases the pollution of residual fluid to formation,but also settles the difficulty of lowering oil well pump and swab in heavy oil wells.That raises the safety coefficient and output power to reach the objective of induced flow.
