摘　　要：充分运用压力导数比压力本身更敏感的突出特点,通过对压力及其导数双对数曲线的过渡段、径向流动段起始时间的统计分析,并利用压力及其导数双对数曲线主要阶段特征,与储层静动态参数紧密结合对储层作出正确分析结论,提出了低渗储层压裂选层的原则及条件。By full use of prominent features of the pressure derivative being more sensitive than the pressure itself,through statistical analysis for the start time of the transition section and the radial flow section of the double logarithmic curve of pressure and its derivative and by utilizing the main stage features of them,combining with reservoir static and dynamic parameters closely,the right conclusions are made,principles and conditions of selecting fractured layer to low permeability reservoir are proposed.

关 键 词：导数曲线 评价储层 选层条件 压裂增产
