以有用孔隙度、可动流体饱和度、主流喉道半径和启动压力梯度作为低渗透储层分类评价的参数,利用模糊数学综合评价方法,对长庆油田5个低渗透区块的开发潜力进行了评价,分类评价结果与区块初期的实际产能符合较好,表明该分类能较好地反映长庆超低渗透储层的真实开发潜力。
Taking the available porosity, the movable fluid saturation, the main throat radius and the starting pressure gradient as the parameters for the classification of low permeability reservoirs, the potential of the five low permeability blocks in Changqing Oilfield was evaluated using the fuzzy mathematics comprehensive evaluation method The results show that the classification results are in good agreement with the actual production capacity in the initial stages of the block, indicating that this classification can better reflect the real development potential of the ultra-low permeability reservoirs in Changqing.
