注CO2驱油藏先导性筛选评价方法

注CO₂油藏前期筛选评价指标体系及综合评价已是一个非常重要的研究课题，鉴于储层条件的非均质性，以及人为因素的影响，为了更有效地对入选注CO₂油藏再进行先导性筛选和评价，从油藏地质、流体性质等多方面建立注气评价指标体系，引入双重不确定条件下多指标决策分析方法，建立能够反映双重不确定性条件油藏注CO₂潜力的综合评价方法，使之可运用于不同注入介质时的油藏前期综合评价和筛选，提高注CO₂驱成功率以使注气提高采收率的效果进一步得到提高。

THE METHOD OF PILOT SCREENING AND EVALUATING RESERVOIR WITH CO2 INJECTION

The indicator system of screening and evaluating reservoirs prior to CO₂injection is a very important research target，because of the heterogeneity of reservoir property and human factors，in order to screen and evaluate the selected reservoirs with CO₂ injection，the comprehensive evaluation method which can reflect the potential of CO₂ injection reservoirs with dual uncertain condition is set up based on the gas injection evaluation indicator system established with reservior geology and fluid property etc.，and the multi-factor decision-making method under the dual uncertain condition is introduced，the method can be used in screening and evaluating the reservoirs prior to injecting different media to improve CO₂flooding and enhance recovery.
