对利用电缆地层测试资料计算储层流度的2种方法进行了比较,认为在低渗透地层积分法比压力降落法更为可靠；探讨了电缆地层测试计算流度与DST采油指数之间的关系,在计算采油指数时因考虑非渗透夹层而提出了“等效厚度采油指数”,使其反映储层的真实产能,实际资料统计表明电缆地层测试流度与“等效厚度采油指数”呈正相关,这为利用电缆地层测试资料进行产能预测提供了新思路.%Two methods to calculate reservoir mobility by using wireline formation test data were compared, and it is believed that the integral method is more reliable than the pressure decline method in the low-permeability reservoir. The relationship between the mobility calculated from wireline test data and the DST productivity index was discussed, and "the equivalent thickness productivity index" was proposed to reflect the real productivity, owing to considering the effect of impermeable interlayers when the productivity index was calculated. A statistical analysis of actual data has shown that there is a positive correlation between the mobility calculated from wireline test data and "the equivalent thickness productivity index", and it may provide a new thinking line for predicting productivity by wireline formation test data.
