- 摘要:
气井实施有机解堵可解除井筒及地层堵塞，提高气井产能。沙坪场气田天东93井等4口井在连续加注缓蚀剂多年后实施了不停产有机解堵，在未做配伍性试验的情况下直接从油套环空加注药剂，导致解堵效果不佳。深入剖析解堵工艺后，提出了有机解堵在沙坪场气田推广应用中下一步应重点开展的工作：选择合适的解堵剂；结合气井井身结构和入井液加注年限，选择合适的解堵方式和加注途径。
Implementation of organic plugging removal in gas well can remove plugging in wellhole and stratum and improve gas well production capacity efficiently. Conducted is organic plugging removal with no shutdown after four wells in Shapingchang Gas Field were continuously filled with corrosion inhibitor for many years. Direct corrosion inhibitor filling into oil set of annulus with no compatibility test resulted in poor plugging removal effect. Conducted is deep analysis on plugging removal process and proposed is an important work in next step for organic plugging removal popularization and application in Shapingchang Gas Field: selection of suitable plugging removal agents and filling ways of plugging removal agents according to different gas well bore structures.
