摘要
文章从气液两相流原理出发,选用适合低产积液井排液模型,模拟计算了积液井在不同生产油管下的井筒压力剖面。根据研究结论,将现场两口低产积液井原来的外径50.8 mm(2 in)油管更换为外径38.1 mm(1.5 in)小油管,实现了稳定生产,效益显著,在低产积液井上具有推广意义。
The liquid discharge model of liquid accumulated well with low oil output is selected based on gas-liquid multiphase flow theory and applied to calculate simulately the wellbore pressure profile of the liquid accumulated wells with different oil production tubes. According to the research results,the original D 50.8 mm oil production tubes are replaced with the small D 38.1 mm oil production tubes in such two wells,which realizes steady production and remarkable benefit. This approach can be widely adopted in other accumulated wells with low oil output.
