摘　　要：针对CB油田油井在中高含水期生产过程中存在的问题,通过对起泡剂、稳泡剂和基础酸液配方的筛选研究及施工工艺的优化等基础研究工作,分别在常规井和水平井中采用泡沫暂堵分流技术进行地层解堵酸化工艺措施。该项工艺的应用,在有效解除该油藏因地层微粒物运移引起的近井地带堵塞的同时,较好地避免了在油水关系复杂的层内条件下常规酸化解堵措施易引起的油井含水上升等问题。Aiming at the problems of oil wells in CB oilfield during medium-high water cut production, and through basic research- es on the screening of foaming agent, foam stabilizer and basic acid formulation and the optimization of the construction process, the foam temporary plugging shunt aeidizing technology is applied in conventional wells and horizontal wells in order to remove for- marion plugging. The application of this technology can effectively remove the near wellbore block of this reservoir arising from the migration of formation particulate. Meanwhile, it can also avoid the problems such as water cut rising easily caused by conventional acidizing broken down under complicated intraformational condition of oil-water relations.
