摘要
对汤源断陷始新统一渐新统(E?^(-5)-E?)泥岩段毛细管压力封闭能力进行了论述,同时对该区断层封闭性作了探讨。并提出了该区泥岩层和煤层的浓度封闭作用。最后从封闭条件评价该区的含气远景。
We discussed the properties of capillary pressure seal about the mudstone intervals
of Eocene series-Oligocene Series (E_2^(2 3)--E_3~1) in Tangyuan fault depression, and in-
quired into the fault sealing properties in this region simultaneously. The effection of
concentration seal about the mudstone intervals and the coal seams in this area is also
put forward. Based on the sealing properties, the gas bearing prospertive values in this
region are evaluated.
