纯化油田中高含水期开发技术界限

Technical limits of Chunhua oilfield development in middle and high water cut periods.

针对纯化油田地质及开发特征 ,评价了该油田目前的开发效果。利用统计分析和油藏工程方法 ,确定了纯化油田中、高含水期开发的技术界限 ,包括合理井网密度、合理注采比、合理井底流压、合理采油速度、合理注水速度、合理注水压力、平均单井日产油量及经济极限含水率等开发指标。

According to geologic and development characteristics of the oilfield, the present development effect of Chunhua oilfield is evaluated. Technical limits of Chunhua oilfield development in middle and high watercut periods are determined by using statistic analysis and reservoir engineering method. It includes development indexes of reasonable well spacing density, reasonable injectionproduction ratio, reasonable bottomhole producing pressure, reasonable oil recovery rate, proper flooding rate, proper waterflood pressure, average daily oil production of single well, economic limit water cut and so on.
