沙南油田沙102井区梧桐沟组油藏为一个滚动开发油藏,从投入注水开发至全面注水经历了6年时间,区块开发数据不能真实反映单井情况,为制定合理可行的开采技术政策界限,主要以典型井组和典型单井为分析目标,按照同一投产时间或将同一生产阶段进行数据统计和分析的方法,并结合经验公式计算、矿场统计分析方法和数值模拟等方法,以经验公式法和数值模拟为参考,矿场统计分析方法为主;做到宏观区块整体指标与具体典型井组、典型单井情况相结合。
The Wutonggou Formation reservoir in Sha 102 well area of Shanan oilfield is a rolling development reservoir. It has been 6 years since it was put into water injection development to full water injection. The data of block development can not truly reflect the single well conditions. In order to develop a reasonable and feasible mining technology Policy boundaries, mainly in the typical well group and typical single well for the analysis of the target, according to the same production time or the same production stage data statistics and analysis methods, combined with empirical formula calculation, statistical analysis methods and numerical simulation methods, Taking empirical formula method and numerical simulation as reference, the mine statistical analysis method is the main method; combining the overall macroscopic block indicator with the specific well group and typical single well condition.
