摘要(Abstract)：

为了研究升平地区缓坡带坡中隆葡萄花油层油的分布规律,在研究其油藏类型及油水分布规律的基础上,通过坡中隆富油程度与供给条件之间关系分析,利用断裂密集带划分、运移路径数值模拟等方法,对控制升平缓坡带坡中隆葡萄花油层油富集主控因素进行了研究。结果表明升平缓坡带坡中隆葡萄花油层油富集有3个主控因素:坡中隆与油源区距离控制油富集程度,距离油源区越近油越富集,越远则油不富集;EW向断裂密集带阻挡作用控制油富集程度,阻挡作用越弱油越富集,越强则油不富集;侧向运移路径分布密度控制油富集程度,油侧向运移路径密度越大油越密集,越小油不富集。
In order to study the oil distribution law in Putaohua oil reservoirs of the central uplifts of Shengping Slope Belt,on the basis of the researches on the reservoir types and distributions of the oil and water,through the relation analysis on the oil enriched degree and supply conditions in the uplifts,the main controlling factors of the oil accumulation were studied with the help of the following methods: division of the dense fault belts,numerical simulation of the migration paths and so forth. The achievements show that the factors indicate as follows: the oil enriched degree is controlled by the distance between the uplifts and oil source regions,the closer the distance is,the more oil will be enriched,vice versa; the degree is dominated by the barrier action of the dense EW fault belts,the weaker the action is,the more oil will be accumulated,otherwise the oil is not enriched; the degree is determined by the distribution density of the oil lateral migration paths,the denser the paths are,the more oil will be trapped,whereas the oil is not enriched.
