| Abstract: | Xujiahe Stage Second Segment(Tx2) formation is a low porosity and permeability or extra low porosity and permeability sand reservoir in Hechuan gas field.Logging evaluation of the reservoir effectiveness is important and difficult.Analyses results about this reservoir show that: interstitial material of Xujiahe Stage Second Segment(Tx2) reservoir rock is complicated and lithology is fine;reservoir properties are not good;formation water is high salinity and there is thick water film;they have great impacts ... |
