Compound active block remover dealing with water-lock applied in Tahe Gas Condensate Field

No.1 Tahe Production Plant,SINOPEC Northwest Company,Luntai,Xinjiang 841604,China

摘要: 在凝析气藏的开发过程中,受外来液、地层水造成的“水锁”现象,致使气相渗透率明显降低,天然气和凝析油产量大幅下降,严重影响了凝析气藏的开发效果。通过塔河油田的小规模凝析气藏的水锁现象,对“水锁”的机理进行分析,对实施的多种解除“水锁”的技术手段进行综合效果评价,介绍了复合活性解堵剂解除“水锁”技术在塔河油田凝析气藏开发中的应用。

Abstract: During explorations of gas condensate reservoir,external fluid and formation water may cause"water-Lock",which makes gas permeability decrease obviously and further reduces the yield of naturalgas and condensate oil.Taking water-locks in small gas condensate reservoirs of the Tahe Oil Field asexamples,lock mechanism was analyzed and several methods dealing with locks were compared.A tom-pound active block remover was introduced and applied in the Tahe Uas Condensate Field.
