摘　　要：从单井的测井资料入手,研究了石炭系单井的油水分布规律。进而又对石炭系的油水空间分布作了进一步的研究,应用系统组合的观点,认为石炭系油藏由3～5个油水分布系统组成,每个油水分布系统含非渗透盖层和油水组合体系两部分。石炭系的圈闭类型属披覆于奥陶系上部的低幅度背斜构造。在上述研究基础上,结合沉积相特征提出了石炭系的油水分布模型。Starting with single well log data analysis,the oil and water distribution as well as spatial dis-tributing rule in Carboniferous reservoir are studied.From the view point of systematic combination,it is pro-posed that the Carboniferous reservoir consists of about 3and5oil-water distributing systems,each of which is divided into impermeable caprock and oil-water combination system.The trap type of Carboniferous is con-sidered to be a low-amplitude anticlinal structure overlying the upper part of Ordovician.According to these researches and corresponding sedimentary facies characteristics,A model of Carboniferous oil-water distribution is proposed in this paper.
