中文摘要:
      针对潜山裂缝油藏在注水开发过程中易在裂缝系统中形成水窜,造成基质系统动用程度低,从而降低整体水驱效率的问题。以渤海X油田为例,参考油田实际特征参数,应用数值模拟软件示踪剂追踪技术定量表征基质、裂缝的产油规律,进而划分开发阶段。根据不同开发阶段主要矛盾,分别采取降压开采、脉冲注水、周期注水和异步注水共四种开发模式,从而构建了潜山裂缝油藏不稳定注水技术体系。与常规注水方式相比,不稳定注水体系能够减缓注水矛盾,提高基质生产能力,从而提高整体注水驱替效率,改善潜山裂缝油藏开发效果。
英文摘要:
      For buried hill fractured reservoirs, water channeling in fracture system is easily formed in the process of water flooding development, resulting in low matrix system utilization, thus reducing the overall water flooding efficiency. Taking Bohai X oilfield as an example and referring to the actual characteristic parameters of the oilfield, the oil production performance of matrix and fracture system is quantitatively characterized by numerical simulation software tracer tracing technology. According to the main contradictions in different development stages, four development modes are adopted, namely, depressurization production, pulse water flooding, periodic water flooding and asynchronous water flooding, thus, unsteady water flooding system for buried hill fractured reservoir is constructed. Compared with conventional water flooding methods, unsteady water flooding system can alleviate the contradiction of water flooding, improve the production capacity of matrix system, thus improve the overall water flooding efficiency and improve the development effect of buried hill fractured reservoirs.
