摘　　要：影响容积法储量计算精度的因素之一是储层的有效厚度取值。有效储层厚度确定得准确与否，主要与下限标准定得是否合理有密切关系。本文通过对川东地区石炭系储层特征的综合研究，结合测井、测试资料，对石炭系储层下限标准的确定方法进行了归纳分析，提出了浮力－毛细管阻力法及相渗透率－产量法两种新的储层下限确定方法，并对各种方法进行分析，推荐了较好的确定裂缝－孔隙型碳酸盐岩储层下限标准的方法。The value selection of net pay thickness of reservior is one of the factors affecting the precision of reserve calculation by volumetric method and is closely related to the determination of reservoir lower limitation.Based on the synthesis of reservoir characteristics,combined with the log and experiment data in eastern Sichuan basin,two new methods of buoyancy capillary resistance and phase permeability production are proposed to determine the lower limitation of reservoir.These new methods are analyzed in detail and recommended as effective method to determine the lower limitation for fissure pore carbonate reservoir.
