Abstract: In recent years,though considerable commercial oil-gas flowwas discovered in all kinds of carbonate,volcanic rock,metamorphic rock and lowresistivity sandstone strata,howto usewell logging datato continue to find oil and gas reservoir in high efficiently andmore accurately,and howto evaluate water-flooded oil bed are still very difficult.According to the complicated features of various-type oil-gas reservoirs in LiaoheOilfield,it is discussed the well loggingseries relatedto several complicatedoil-gas reservoirs,and evaluated differentoil-gas reservoirs byusing sufficiently richwell loggingdata and advanced technology,and got niceapplication effect.

Key words: complicated oil-gas reservoir, lowresistivity sandstone;well logging series, advanced technology, reservoir evaluation
