摘  要:雁翎油田雾迷山组潜山油藏为碳酸盐岩底水块状油藏,早期曾开展过井组注氮气现场试验,形成了44 m的油柱,目前油藏已进入可采储量采出程度高和含水率高的双高开发后期,亟需转变开发方式。以室内实验、早期现场井组试注经验、测井解释成果等为基础,通过优化地质模型,搭建数值模拟高性能云计算平台,优化双重介质潜山油藏数值模型,在网格精度为60 m×60 m×3 m,总网格数为97×10^4的模型基础上,开展了注气重力驱高精度数值模拟,编制了雁翎油田潜山油藏注气重力驱方案。方案预测提高采收率11.8%,最终采收率可达43.4%,效果显著,可为同类型油藏的开发方案设计提供借鉴。The buried hill reservoir in the Wumishan formation of Yanling oilfield is a massive carbonate reservoir with bottom water,in which field tests of nitrogen injection had been carried out in the past and a 44 m high oil column was formed.At present,the reservoir has entered the late development stage of high water cut and high recovery factor,and the development mode needs to be changed.Based on the data of laboratory experiments,early nitrogen injection field tests and well logging interpretation,the paper optimizes the geological model and establishes a high performance cloud computing platform for numerical simulation.The simulation model for dual porosity buried hill reservoirs is optimized,a high resolution numerical simulation is carried out based on the model with grid precision of 60 m×60 m×3 m and the total grid number of 97×10^4,and a gas injection gravity drainage plan has been made for the buried hill reservoir in Yanling oilfield.It is predicted in the plan that the recovery factor will be improved by 11.8%,the ultimate recovery factor will reach 43.4%and good results will be obtained,which can provide references for the development of similar reservoirs.
