鄯善丘陵交界区域三间房组油水关系研究

Oil-water Relationship of Sanjianfang Formation in the Region between Shanshan and Qiuling Area

在区域地质特征研究基础上,结合沉积相、储集层特征研究成果,分析了鄯善-丘陵交界区域中侏罗统三间房组油水分布影响因素,并利用试油、测井、生产等数据,确定了油水界面。认为研究区内无统一的油水界面,油水关系复杂,总体呈现出西高东低、北高南低的态势。因而,鄯善-丘陵交界区域三间房组油水关系表现为构造控油为主,但油水界面倾斜的特征。此研究成果为后续的剩余油挖潜措施的实施提供了指导。

On the basis of the regional geological study and in combination with the research result of sedimentary facies and reservoir characteristics,the influential factors of oil-water distribution in Sanjianfang Formation of Middle Jurassic were analyzed,the oil-water interface was determined by using the data of oil testing,well logging and production.It is believed that there is no unified oil-water interface with complex oil and water relations,which reveals that there exists the trend of high altitude in the west and low altitude in the east,high in the north and low in the south.Therefore,the relations of oil and water of the Sanjianfang Formation in the region between Shanshan and Qiuling Ares is presented that oil is controlled by structures with tilting oil-water contacts.The results provide guidance for tapping the potential of remaining oil.
