陕北M油田长8油藏注水井欠注原因及治理措施

Causes of Insufficient Injection and Remedial Measures for Injectors in Chang 8 Reservoir of M Oilfield in Northern Shaanxi

针对陕北M油田长8油藏注水井高压欠注的问题,通过对储层特征、注入水和地层水的配伍性、井筒及地面注水系统的分析,找出陕北M油田长8油藏注水井的欠注原因并提出相应的治理措施,对该区块合理实施降压增注措施和保持长期稳定注水高效开发具有重要意义,为下步治理同类油藏提供了借鉴。

The cause of insufficient injection and remedial measures for injectors in Chang8 oil reservoir of M oilfield in northern Shaanxi was studied by analyzing rock characteristics, reservoir physical properties, the compatibility of injection water and formation water,wellbore and water injection system.It is of great significance to reasonable measures of drawdown and augmented injection and long-term stable and efficient development of the reservoir.This shall provide references for similiar reservoir management in the future.This shall provide references for similiar reservoir management in the future.
