Study of Carboniferous Exploration Prospects in New South Margin Area of Block B, Pre-Caspian Basin
Abstract:
The new south margin area of Block B is a key risk exploration area in southeastern Pre-Caspian Basin. 4 risk exploration wells were drilled in 2013, and all they have seen oil flow from Carboniferous (KT-I, KT-II), indicating a good exploration prospect. This paper, based on petroleum geologic condition analysis and reservoir characteristic correlation, believes that the main control factors of petroleum accumulation are the hydrocarbon filling capacity deciding reservoir limit and the favorable shoal facies deciding reservoir distribution. Moreover, this paper believes that KT-I has better exploration potential than KT-II, and No.6 shoal developed in upper KT-I should be taken as the key target area of subsequent exploration; In addition, higher uplift possibly exists in the areas adjacent to the southern and southeastern study area, whose petroleum accumulation conditions may be superior to that of the study area, and it should be taken as the preferred area for conducting risk exploration expansion.
