摘　　要：沈625块潜山油藏具有双重介质的复杂特点,开发中暴露出多种矛盾,通过注水可行性分析以及注水参数优化设计,给出了注水开发过程中的主要做法,并对措施实施后的效果进行了评价。其中,直井注水、水平井采油方式的应用对于新型注水开发模式进行了有益的探索,实施后效果明显,可为同类油藏的注水开发提供一定的借鉴。Buried hill reservoirs in Block Shen625 have dual media, and have revealed many problems during development. Feasibility analysis of waterflooding and water injection parameter optimization provides us the measures for waterflooding and evaluates the response of the measures after implementation. Application of vertical well injection and horizontal well production is a useful probe into new waterflooding mode. The response is notable after implementation. This provides some reference for waterflooding in similar reservoirs.
