Analysis on the exploitation feasibility of Sa-0 reservoir in Duanxi of Bei-1 Area in Daqing Oil Field

分析了密闭取心和测井资料 ,确定了大庆北一区断西萨零组储集层的类型 ,研究了萨零组油层的沉积背景和沉积特征 ,测定了储层物性参数 ,计算了地质储量和可采储量 ;结合试油试采结果 ,阐述了萨零组储层开发的可行性 .结果表明 :北一区断西萨零组S0 2 单元油层为主要含油层 ,是开发的主要对象 ;北一区断西 15km2 内 ,萨零组油层控制地质储量为 2 65× 10 4 t ,可采储量为 111.0 9× 10 4 t,具备了开发的物质基础 ,且具有较好的开发潜力 .

Based on the analysis of sealing core drilling and log analysis, the reservoir type of Sa-0 reservoir in Duanxi of Bei-1 Area in Daqing oil field is identified and the depositional environment and depositional feature of Sa-0 member are studied, the physical property parameters of this reservoir are determined. Then the reserves in place and recoverable reserves of this reservoir are calculated. Finally, taking into account the result of production test, exploitation feasibility of Sa-0 reservoir is evaluated. The result shows that S 02 unit of Sa-0 reservoir in Duanxi of Bei-1 Area is the main reservoir containing oil and is the main reservoir for production. The reserves in place of Sa-0 reservoir is 265×104 t, it's recoverable reserves is 111.09×104 t. Sa-0 reservoir in Duanxi of Bei-1 Area has a production capacity to a certain extent, and has a nice potential of development.
