摘要
Abstract
Sulige gas field in Ordos basin is the largest terrestrial gas production field in China .As a typical tight sandstone gas pool , distribution of reservoirs of the main gas -producing strata in Sulige gas field---the 8th mem-ber of Shihezi formation in Permian system (P2h8 for short), is mainly controlled by detailed sedimentary facies .But disagreements about detailed sedimentary facies still exist in the Block S 47---an important new region in the west-ern part of Sulige gas field .Detailed sedimentary facies of P 2h8 in the Block S47 were studied on the basis of drilling core observation , analysis of well logs and samples .It is considered that the strata of P 2h8 in the Block S47 was de-posited in braided delta front , which can be further sub -divided into subaqueous distributary channel , estuary bar , sand sheet , subaqueous levee and interdistributary bay etc .5 detailed sedimentary facies .The most favorable reser-voir is subaqueous distributary channel overlaid sand bodies and estuary bar sand bodies secondarily .New under-standings on detailed sedimentary facies and distribution features provide theoretical foundations for reservoir predic -tion and integrated exploitation by horizontal wells in the Block S 47.关键词
