摘要:
目前常用的深井气举降压设计与变流压设计方法均具有一定局限性,而针对气举变流压设计方法与降压设计方法结合形成的新型混合气举工艺技术尚未有深入研究。根据新型混合气举方式物理模型,从工作原理出发建立了新型混合气举方式的工艺设计方法和优化方法,并与变流压设计方法、降压设计方法进行了对比分析。结果表明,新型混合气举方式的注气深度和排采能力大多介于降压设计方法和变流压设计方法之间,有时超过变流压设计方法,不仅注气深度增加、排采能力增强,还具有便于地面判断工作阀的级次、气举生产稳定和地面能控制气举阀开闭状况等降压设计方法所具有的优点; 新型混合气举方式充分地利用了地面注气压力,提高了气举系统效率,其适用范围亦包含降压设计和变流压设计方法的适用范围。本文研究成果为新型混合气举方式完井管柱优化设计和生产参数优化奠定了理论基础,具有较好的推广应用价值。
Abstract:
At present, the commonly used deep well gas lifting design methods controlled by pressure reduction or flowing pressure have some limitations. However, the new mixed gas lifting technology formed by combining the above two methods is still in the primary study stage. This paper, according to the physical model of the new mixed gas lifting method, establishes the process design and optimization methods based on the working principle, and makes comparison with the variable flowing pressure design method and the pressure reduction design method. The results show that the gas injection depth and drainage capacity of the new mixed gas lifting method are mostly between the pressure reduction design method and the variable flowing pressure design method, sometimes exceeding the variable flowing pressure design method. Besides the increased gas injection depth and the enhanced drainage and production capacity, it also has the advantages of easy to judge the level of working valve on the ground, the stable gas lifting production, and the opening/closing control of gas lifting valve on the ground. The new mixed gas lifting method can fully utilize the surface gas injection pressure, improve the efficiency of gas lifting system, and its application scope also includes that of the pressure reduction design and the variable flowing pressure design method. The research results of this paper lay a theoretical foundation for the optimized design and production parameter optimization of the new mixed gas lifting method, and have good application significance.
