摘要:

目前,新浅45断块油田进入高周期吞吐阶段,受断层、储层物性、汽窜、边水、采出状况等静、动态因素的影响,出现了压力低、单井日产水平低、油气比低,关停井较多、低效无效生产井多、开发效益差等诸多问题,为改善油藏开发效果,进一步提高采收率,在全面分析该区块生产开发动态的基础上,综合地震、地质分析,采用精细地质建模与数值模拟相结合的方法,找出剩余油的分布特征,并依据单井的平均剩余油饱和度、采出程度等不同参数建立了5种剩余油类型的评价标准,从而总结出适用于单井剩余油分布规律的研究方法,为油田后续精细调整和挖潜提供指导依据。

Abstract:

At present, the new shallow 45 fault oil field has entered the high cycle stage of huff and puff, which is affected by the static, dynamic factors such as fault, reservoir physical property, steam channeling, edge water and recovery situation. There are a lot of issues such as low pressure, low daily level of single well, low oilgas ratio, more shutting down wells, more inefficient and ineffective production wells, poor development efficiency. In order to improve the development effect of reservoirs and further improve the oil recovery factor, on the basis of comprehensive analysis of the production and development dynamics of the block, meanwhile, integrating earthquake and geological analysis, the distribution features of remaining oil were found out using fine geological modeling and numerical simulation. And the evaluation criteria of five kinds of remaining oil types was established according to the parameters such as the average remaining oil saturation and the recovery degree of single well. The research method suitable for single well remaining oil distribution law was summed up, providing guidance for subsequent fine adjustment and tapping the potential in oilfield.
