摘　　要：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 mob ility by using wireline formation test data were compared, and it is believed that the integral meth- od is more reliable than the pressure decline meth- od in the low permeahility reserw）ir. The relation- ship between the mobility calculated from wireline test data and the I）ST productivity index was dis- cussed, and ＂the equivalent thickness productivity index＂ was proposed to reflect tile real productivi- ty, owing to considering the effect of impermeable interlayers when the productivity index was calcu- late＆ A statistical analysis of actual data has shown that there is a positive correlation between the mobility calculated from wireline test dala and ＂the equivalent thickness productivity index＂, and it may provide a new thinking line for predicting productivity by wireline formation test data.
