Abstract:

In order to improve the economic profit of exploratory development of glutenite reservoir in Lijing oilfield, the characteristics of reservoir and the distributions of the oil-bearing formation  are studied using data of coring,logging,well test etc. It is concluded that the main reservoirs are glutenites of the third and fourth of members of Shahejie Formation, that oil-bearing formations focus on sets Ⅰ,Ⅱand Ⅲ of the fourth member of Shahejie Formation. Interpretation charts for discriminating oil, water and dry formations are built in the well Li85 area and are applied to interpret and evaluate these kinds of oil-bearing glutenites, this study is useful for estimation of original oil in-place and can provide targets of further exploratory development.

Key words: oil-bearing formation, logging interpretation, water saturation
