油藏滚动勘探开发的实践与经验——以准噶尔盆地石南21井区为例
|
摘要
准噶尔盆地石南21井区头屯河组油藏继2004年建成产能56.49×10~4t以后,利用测井、三维地震、试油试采和动态分析等多种资料开展了为期4年的油藏地质研究。查明了砂体变化规律、断层产状,确定了物源方向,精确识别了沉积微相,精细刻画了储集层、隔夹层及流体的三维空间分布,评价了薄层生产能力,修正了油藏油水界面。经4年的油藏滚动勘探开发,使含油面积、石油地质储量有了大幅提高。
In 2004,the productivity of 56.49×10~4 t of Toutunhe reservoir in Shinan-21 well block in Junggar basin was constructed,after which through 4 years studies of data from reservoir geology are conducted,such as well logging,3-D seismic prospecting,well testing and production and performance analysis,in order to master the variation of sand body,fault occurrence,provenance directions,identify sedimentary microfacies,3-D distribution of reservoir,interbed and fluid,estimate productivity of thin sand,and revise oil-water interface of reservoirs,etc.The beneficial results are remarkable.
