难动用储量精细评价研究与应用

Evaluation Research and Application of Hard-to-Recovery Reserves

为了缓解资源接替不足的压力,改善新区建产规模萎缩的现状,开展了难动用储量精细评价研究。在油藏分类研究基础上,通过进行油藏主控参数优选、权重系数确定、综合距离评价,最优分割分级研究,实现了难动用储量横向分类、纵向分级,进一步完善了区块优化筛选方法,建立了难动用储量筛选评价技术标准。通过应用该研究成果筛选出部分储量优先安排评价部署,实现了滚动扩边规模增储,为保障辽河油田"十三五"原油建产规模奠定了基础。

In order to alleviate the pressure of resource replacement and improve the status of the construction scale shrinking in the new district, we carried out the research on the fine evaluation of hard-to-recovery reserves. Based on the study of reservoir classification, through the study of the master reservoir parameter optimization, the weight coefficient is determined. The comprehensive distance evaluation, the optimal segmentation and classification achieved the horizontal classification and longitudinal grade to hard-to-recovery reserves, further improved the block screening and optimi- zing method, established the technical standard of hard-to-recovery reserves screened and evaluated. By applying the results of the study, we selected parts of the reserves to priority arrange evaluation and deployment, to achieve the scale of increasing reserves by rolling extension, and lay a solid foundation for the protection of Liaohe Oilfield ＂Thirteen Five＂ crude oil production scale.
