摘要
快速有效地排出井筒积液是保障延长气田积液气井高效、持续生产的关键。通过对延长气田积液井现状的分析,归纳对比了目前试验的提产排水、间歇生产排水和泡沫排水等排水采气试验效果,结果表明提产排水可作为中高产井的排水措施,间歇生产排水和泡排相结合可作为低产水井的排水措施,泡排排水采气是可全面推广应用的排水措施。
Quick and effective drainage of wellbore liquid loading plays an important role in ensuring the efficient and sustainable production of liquid-loading well in Yanchang gasfield.Based on the analysis of current situation, the effects of drainage gas recovery tests including increasing production drainage, batch production drainage, and foam drainage were compared and summarized. Results show that the increasing production drainage can be used for middle-to-high water-producing wells, the batch production and foam drainage can be the measures for low water-producing ones, and the foam drainage gas recovery has a value of overall application. This study provides a reference for improving utilization of gas well.
