准噶尔盆地车北地区石炭系发育火山岩油藏，其油水分布规律一直以来未能形成统一认识。利用构造、岩心、测井解释以及试油成果等资料，确定了车北地区石炭系油藏类型为构造—岩性控制的块状油藏。通过对研究区部分井的实际数据统计分析，查明了石炭系原油和地层水性质。在对油藏精细解剖的基础之上，明确了研究区的油水分布特征及其控制因素。研究表明，油水分布主要受构造控制，油层主要分布在构造高部位，同时受岩性岩相、原油稠化作用等因素的多重影响，其中原油稠化作用是研究区局部出现油水并置和倒置的主要原因。

The Northern Chepaizi area of Junggar Basin develops Carboniferous volcanic reservoirs ,and the oil-water distribution regularity failed to form a unified understanding. Based on data of tectonic,core,log interpretation and oil test,the reservoir type of the Northern Chepaizi area is the massive reservoir controlled by structure and lithology that is determined. Through the statistical analysis of some wells practical data in the study area ,the Carboniferous oil and famation water properties are confirmed. Based on the fine dissection of reservoirs ,the oil-water distribution regularity and main controlling factors in the study area are made clear. The results show that the oil-water distribution is mainly controlled by the structure,the oil is rich in structural high part. Lithology-lithofacies and oil thickening also have an affect on the distribution regularity of oil-water,and oil thickening is the main factor of oil-water apposition and inversion.
