摘要
对目前定量评价碳酸盐岩孔洞型储层有效性的方法进行了分析,从储层宏观特征、微观孔隙结构研究入手提出了一种新的三元耦合(孔隙度下限、平均有效孔隙度、累计有效孔隙厚度)有效性定量评价方法。该方法考虑了一般的宏观孔隙度参数,融入了微观孔隙结构参数(排驱压力、平均孔喉半径),综合考虑储层纵向发育规模对产能的影响,弥补了用单一孔隙度因素表征的不足,提高了有效性定量评价的精度。该方法在塔里木盆地塔中、轮古地区的实际应用中取得了较好的效果。
Abstract. Some methods for quantitatively evaluating effectiveness of carbonate vuggy reservoir are discussed. Based on studying the macroscopic and microscopic pore structures, a ternary factors coupling （porosity lower limit, average effective porosity and cumulative thickness of valid pore） method is proposed. In this method, many parameters are used for evaluating effectiveness, such as macroscopic porosity, microscopic pore structure parameters （displacement pressure and average pore throat radius） and the vertical reservoir development degree. It made up for reservoir evaluation with only porosity and enhanced the accuracy of evaluating reservoir effectiveness. It has been applied to Tazhong and Lungu zone of Tarim basin, and good effects have been obtained.
