川东嘉二段孔隙层下限及分类与评价

RESERVOIR′S LOW LIMIT,CLASSIFICATION AND EVALUTION OF MEMBER Ⅱ OF JIALINGJIANG FORMATION(LOWER TRASSIC) IN EASTERN SICHUAN

本文运用多种分析手段，采用新的思维和方法，划分出川东嘉二段孔隙层的绝对孔喉下限、有效孔喉下限、孔隙度绝对下限及孔隙度产出下限。提出孔喉结构的新参数并用之于储层的分类与评价。下限标准符合于生产实际，分类与评价效果良好、实用。

Reservoir′s absolute low limit of throat,effective low limit of throat,absolute low limit of porosity and productive low limit of porosity of member Ⅱ of Jia LingJiang formation in Eastern Sichuan are fixed by many analytic methods under new througts.New para.meters of pore throat texture are put forward and are used for classification and evaluation of reservoir. The standards of low limit are suitable in practice. The effect of classification and evaluation is practical and effective,and has been used in production.
