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

Practice and Experience for Rolling Exploration and Development of Petroleum Reservoir——An example from Shinan-21 well block in Junggar basin

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 56.49×10^4t 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.
