摘要:
凝胶封堵效果评价实验从宏观角度进行研究,但无法从微观层面对孔隙动用状况进行描述。为解决该问题,利用核磁共振从微观角度研究凝胶封堵效果,运用弛豫时间谱转换成喉道半径分布法和各喉道区间饱和度计算方法,研究不同渗透率岩心在不同驱替阶段油水在孔隙空间中的分布,从而确定凝胶封堵的渗透率界限。该研究在一定程度上实现了对凝胶封堵效果的评价,对油田开发技术调整具有重要意义。
Abstract:
At the macroscopic level,the plugging effect of gel can be evaluated.However,the producing status of cores can not be described at the microscopic level.To resolve this problem,the plugging effect of gel was studied by NMR technology from microscopic perspective.The distribution of oil and water in pore space in different permeability cores was derived by converting relaxation time spectrum to throat radius distribution and calculating saturation between throats.As a result,the permeability limits of gel plugging were determined.This study provides more comprehensive understanding of gel plugging effect,and is of important significance to the development adjustment of existing oilfields.
