| 摘要: |
| 建立了特高含水开发期油藏绿合调整效果评价指标体系，分为注采状态评价指标、开发动态评价指标、经济效 益评价指标等3大类，包括井网密度变化率、注采对应率变化值、水驱储量控制程度变化值、含水率评价系数降低值、 存水率评价系数降低值、平均年增油程度、采收率增加值、耗水量降低值、产出投入比等9项子指标。基于模糊综合 评判原理和层次分析法，提出了综合调整效果的模糊综合评判方法。对胜轮油田“十五”期间12个综合调整单元的 调整效果进行了模糊评价，结果表明，该方法能综合反映多方面的调整效果。 |

| Abstract: |
| Evaluation indexes systems of reservoir comprehensive adjustment efTecl in ultra-high water cut stage were established ,which can be divided into three types including evaluation indexes of injection-production condition，development and economic benefit. These indexes can also be subdivided into nine indexes inclutling variaiion rale of well spacing density, variation of injection-to-producing-wetl corresponding ratio, variation of reserve cuntrollable degree of water drive? decrease of evaluation coefficient of water cut, decrease of evaluation coefficient of water storage，average oil increment degree per year, increase of oil recovery efficiency, decrease of water consumption t ratio of output and input, A fuzzy comprehensive evaluation method of reservoir comprehensive adjustment eflfecl was presented on the basis of fuzzy comprehensive evaluation theory and analytical hierarchy process. Fuzzy evaluation of adjustment effect was performed on 12 adjustmetil nails of Shengtuo Oilfield during tenth five-year plan period. It is indicated that the method can coitiprehens?iveLy reflect adjustment performance from many aspects. |
