沙子湾自适应深部调剖体系筛选与评价

Screening and Evaluation of Shaziwan Adaptive Deep Profile Control System

针对沙子湾油田地层条件,笔者研制了自适应深部调剖体系,并对该体系性能进行了室内评价。该调剖体系在现场地层水源条件下,具有较高、强度的封堵作用;在需调剖地层条件下,能够保持长期稳定性;具有较好的可运移性,能够保证进行较大剂量的较深部封堵;调剖药剂与地层配伍性好,来源广,成本低,适合工业应用,可以大规模推广使用。

An adaptive deep profile control system has been developed for the formation conditions of Shaziwan Oilfield,and its performance has been evaluated in laboratory.The profile control system has a strong plugging effect under the condition of field water source,can maintain long-term stability under the condition of profile control formation,has good migrability,and can ensure a larger dose of deep plugging.The profile control agent has good compatibility with the formation,wide source and low cost.It is suitable for industrial applications and can be widely used.
