| 摘 要： | 通过常规物性、岩石及铸体薄片、重矿物、X射线衍射、扫描电镜等多项测试方法,对鄂尔多斯盆地姬塬地区长2储层特征及油藏控制因素进行分析.该储集层砂岩类型以长石砂岩为主,岩屑长石砂岩次之,储层物性相对较好.区内油藏类型可分为构造-岩性油藏和岩性-地层油藏,东西向展布的鼻隆构造与三角洲平原分流间洼地泥岩遮挡是主要的油藏控制因素.

| Abstract: | The reservoir characteristics and control factors of chang 2 reservoir of Jiyuan region in Ordos Basin are analyzed and studied by varied methods,including examination of the normal physical properties,thin-section & casting thin-section,heavy minerals,X-ray diffraction and SEM analysis.The reservoir-rock types in Chang 2 reservoir are mainly arkose,secondly lithic arkose sandstone.the reservoir properties are relatively superior.The reservoir types in the area can be divided into structural-lithological and lithologic-stratigraphic reservoir.the EW spreading nose-uplift structure and the mudstone screen of delta plain interdistributary area depression are the main controlling factors for reservoir. |
