摘要
目前渤海S油田已处于高含水期开发前期,为了挖潜该油田的潜力,稳定油田的生产,在精细油藏描述和动态资料分析的基础上,探讨了该油田在高含水期的剩余油的形成与分布的控制因素,分析了普通稠油油田在高含水期潜能挖潜的主要方向,并通过采取针对性较强的配套措施,取得了高效开发效果.这表明,打加密调整井,挖潜剩余油富集区潜力、细分开发层系,进行产液结构调整和放大生产压差,实施大泵提液强采是普通稠油油田高含水期提高采收率普遍适用的有效措施.
At present,the Bohai S oilfield is in the early stage of high water cut development.In order to tap the potential of the oilfield and stabilize the production of the oilfield,based on the detailed reservoir description and dynamic data analysis,the control factors of formation and distribution of the remaining oil in the oilfield in the high water-cut stage is discussed.The main direction of tapping the potential of ordinary heavy oil fields in the high water-cut stage is analyzed,and efficient development effects have been achieved by adopting highly targeted supporting measures.This shows that drilling infilling adjustment wells,tapping the potential of the remaining oil-rich area,subdividing the development stratum,adjusting the structure of liquid production and enlarging the production pressure differential,and implementing large pump liquid extraction and strong recovery are effective measures generally applicable to increase the recovery rate of ordinary heavy oil fields in high water-cut stage.
