北乌斯丘尔特盆地含油气系统及勘探前景分析
Hydrocarbon Systems in the North Ustyurt Basin and Their Exploration Prospects
摘要
Abstract
By using theories for hydrocarbon-bearing systems, and with consideration to the quality of hydrocarbon-generation kitchens, hydrocarbon-generation efficiency, together with reservoir formations, caprocks, traps, reservoir formation history and structural frameworks, the North Ustyurt Basin can be divided into 3 hydrocarbon-bearing systems.Researches have been performed for static geologic elements and dynamic geologic processes of various hydrocarbon-bearing systems to determine oil-gas exploration prospects and to highlight key objectives for future researches.Research results show the Mid-Jurassic-Mid Jurassic, Lower Cretaceous (already knew)+Eocene (supposed) hydrocarbon-bearing systems are characterized by large scales and relatively favorable reservoir assembly combinations.Consequently, these systems have the highest exploration potential.Keys for future exploration operations include identification of favorable reservoir structures and assessments for matching between periods with formation of traps and periods with hydrocarbon generation and discharging;On the other hand, the other 2 hydrocarbon-bearing systems are poorly explored with hydrocarbon source rocks remain restrictions over hydrocarbon accumulation.Upper Paleozoic-Carboniferous (already knew) hydrocarbon-bearing system has the lowest exploration level.Consequently, these formations may serve as targets for long-term exploration.Relevant research results may provide importance guidances over identification of key exploration fields and targets in the Basin.关键词
