四川盆地下侏罗统大安寨组层序分析

Sequence analysis of Da'anzai formation of Lower Jurassic in Sichuan Basin

川中大安寨储层属于特低孔隙度、低渗透率的孔隙-裂缝型储层，裂缝以低斜水平缝为主。

The Daanzai reservoir belongs to the type of porosity-fractured reservoir of ultra low porosity and permeability .

川中大安寨油层属于碳酸岩裂缝性油藏，大多数井都需要通过酸化才能投产。

Daanzhai reservoir in the middle of Sichuan is a carbonate fractured reservoir in which most wells need to be acidized before putting into production .
