摘要: 从常规物性特征及测井响应特征方面看,嘉二1亚段与嘉二2亚段具有类似的储层特征,都表现出了良好的储集性。嘉二段岩芯的核磁共振实验分析表明,嘉二1亚段与嘉二2亚段孔隙结构存在较大的差异。嘉二1亚段虽有较大的孔隙度,但孔隙空间主要被束缚流体所占据,利用岩芯的核磁共振实验资料可对储层的有效性进行评价。而由于嘉二2亚段孔隙空间主要被可动流体所占据,可采用喉道半径法来确定有效储层的下限值,以此为标准作为有效储层的判别依据。

关键词: 储层特征, 孔隙结构, 储层有效性, 核磁共振, 喉道半径

Abstract:

Viewed from conventional physical property and well logging response,there is similar reservoir characteristic between T1j21 & T1j22,they are all good reservoirs.NMR analysis of the cores from T1j22 indicates that there are big difference in pore structure in T1j21 & T1j22.Although there is higher porosity in T1j21,the poor spaces are taken up by irreducible fluids.The NMR data can be used to evaluate the reservoir effectiveness.To T1j21 ,the pore spaces are mainly taken up by mobile fluids,the throat radius method can be used to determine the limit of effective reservoirs,and it can be used as criteria to assess effective reservoirs.

Key words: reservoir characterization, pore structure, reservoir effectiveness, NMR, throat radius
