分层段压力监测系统在大庆油田的应用

通过分层测压试验、数值模拟和实测数据分析，研究了分层测压层段的合理划分方法，提出了以开发层系为基础的分层测压井部署方法，优化了测压井部署原则；在分析了不同类型油层、不同井网开发对象的压力分布特点的基础上，指出了分层测压资料在油田开发中的作用，为高含水后期油田测压系统的改造、预防套管损坏、提高固井质量、判断油层的连通状况及隔层的稳定性，指导油田各种增产措施的进行提供了理论依据和实践经验。

Application of Layered Pressure Monitoring System in Daqing Oilfield

After layered manometric testing,numerical simulating and measured data analyzing,the reasonable way of dividing layered manometry interval is worked out, and in this paper it is put out that the optimized principle is to deploy piezometric well in accordance with development layer series. On the basis of analyzing different types of oil layers, pressure distribution of different exploitation well patterns, it is indicated the role of layered manometry data played in the development of the oilfield, which can find application in the amelioration of manometry system, prevention of casing failure, improvement of cement job quality, and it can also be used to estimate connection status and stability of barriers in the late stage of high water-cut.
