摘要
川中嘉二气藏储层岩性类型多, 储层非均质性强, 复杂的岩性组合造成气水层段的测井解释极其困难。在深入分析川中嘉二段储层测井特征的基础上, 通过对试油资料和测井资料的综合分析, 探讨了储层流体性质判别的定性和定量方法, 在此基础上提出了适应本地区储层特征的流体性质判别方法, 即储集层定性识别和气水层多元判别分析方法, 这为气藏的生产提供了依据。
Abstract
The identification of w ate r and gas re lationsh ip in Jia 2
reservo ir in center o f S ichuan Basin by m eans o f traditiona l
log interpretation is qu ite d ifficu lt ow ing to the m ulti rock
types, strong heterogene ity and com plex litho logy. Based on
the analysis o f the log features fo r the Jia 2 gas reservo ir and
comb ined w ith the productiv ity test, var ious m e thods are
d iscussed and brought fo rw ard to identify the flu id
classification, wh ich is useful fo r gas production.
