针对川东北地区通南巴构造带海相碳酸盐岩储层的双孔特征,基于嘉二段、飞三段取芯及测试资料,利用岩心刻度测井的方法,确定储层下限参数,建立适合川东北地区通南巴构造带及邻近地区海相碳酸盐岩储层参数计算模型与评价标准.结果表明:川东北地区通南巴构造带碳酸盐岩储层下限值标准为孔隙度1.6%,裂缝孔隙度0.05%,含气饱和度50%.该成果为川东北地区通南巴构造带海相碳酸盐岩气藏内部参数分布描述与最终形成气藏三维数据体提供了可靠的资料,在实际生产中取得了良好的应用效果,为油田进一步勘探、开发和增产措施提供可靠的依据.

Based on the characteristic of dual porosity texture, drilling core analytical data, tes-ting and well logging data, a calculating model for reservoir parameters suitable for marine car-bonates evaluation in the northeastern Sichuan and adjacent area was established. Evaluation crite-ria were proposed after the determination of inferior limit for reservoir. According to the test data and well logging data, the minimum effective thickness was identified. The results showed that the inferior limit for porosity is 1.6% ,for fracture porosity was 0.05% and for saturation is 50% for the marine carbonate reservoir . Based on the research,the standardization of geologic parameter for the marine carbonate reservoir and the geologic scale for reservoir evaluation were achieved, which provided more reliable data for evaluating the description and distribution of reservoir pa-rameter and creating the 3D data volume for the reservoir of the Tongnanba structural belt in Northeastern Sichuan.
