复杂小断块油藏动态监测技术应用及展望

The application and prospect of dynamic monitoring technology in small complex fault-block reservoirs

苏北盆地溱潼凹陷内发现的油田均为复杂小断块油藏,在开发过程中问题较多,为此先后与大庆、胜利、中原及河南油田等测井公司开展了复杂小断块油藏生产测井技术协作与交流,对动态监测成果在高含水油藏稳油控水、注水开发油田注采结构调整、老油田综合治理、二氧化碳驱油提高采收率等措施方案的科学合理编制及实施效果评价中发挥的重要作用进行了全面总结,同时针对复杂小断块油藏在动态监测中存在的不足提出了认识,从而指导复杂小断块油藏动态监测的下步改进和发展。

Oilfields explored in Qingtong depression of northern Jiangsu basin are mainly small complex fault-block reservoirs which encountered lots of problems in development. For the solutions, cooperation and communication about production and logging technology of small complex fault-block reservoirs were carried out by East China Branch Company with the companies of Daqing, Shengli, Zhongyuan and Henan. This paper made scientific compilation and comprehensive evaluation concerning the significant role played by dynamic monitoring in oil production stabilization and water cut control of high water cut reservoir, in injection-production pattern adjustment of waterflood development oilfield, in comprehensive treatment of maturing oilfields and in EOR by CO2 flooding. Meanwhile, this paper predicted the shortages of dynamic monitoring in small complex fault-block reservoirs and made suggestions for its future improvement and development.
