Division and Estimation of the Paleozoic-Mesozoic reservoir forming combination in North Africa superimposed basin
摘要
Abstract
The North Africa petroliferous basin is a superimposed basin of Paleozoic cratonic basin and Mesozoic depression basin.The Paleozoic-Mesozoic reservoir forming combination is systematically divided into the Triassic basin based on following aspects:①regional distribution of source rocks and reservoir sandstones; ② characteristics and distribution of paleo-structure, main faults, unconformable surface, characteristics and spatial distribution of hydrocarbon migration and transportation systems;③distribution of main source rocks for each different reservoir forming combination;④distribution of cap rock,especially regional cap rock for each different reservoir forming combination. In addition, distribution of different kinds of known traps, as well as preservation conditions of petroleum system is used as factors to identify reservoir forming combination.Three large scales Paleozoic-Mesozoic reservoir forming combinations are recognized, such as Triassic Tagi Formation,Ordovician Hamra Formation and Cambrian R Formation.Based on analysis of source rocks,reservoir and cap rocks in different reservoir forming combinations,it reveals that the reservoir forming combinations are mainly distributed in Hercynian uplift zones and slope zones within the basin.关键词
