摘要 以岩心观察为依据,结合储集层岩性、沉积构造和粒度分析等方法对鄂尔多斯盆地胡尖山—耿湾地区长4+5油层组进行沉积相分析.研究结果表明:研究区长4+5油层组为三角洲前缘沉积,水下分流河道、河口坝、分流间湾、远砂坝及前缘席状砂构成其主要沉积微相.长4+52期水下分流河道砂体之间交叉叠合连片,但水下分流河道、叠置水下分流河道分割性较强,随着湖盆短暂的扩张,长4+51期水下分流河道缩小,分流间湾进一步扩大.在沉积相研究的基础上对长4+52期进行有利相带预测,共预测出5个有利储集相带发育区,为该地区进一步勘探提供依据. Base on well's core data, integrated with reservoir lithology, depositional structure and grain size analyses, the sedimentarymicrofacies of chang 4+5 oil-bearing formation of yanchang formation in hujianshan-gengwan area is studied. The result shows thatfront-delta is the main sedimentary system of Chang6 in the studied area, the subaqueous distributary channel, channel-mouth bar, interdistributary, distal bar and front sheet sandstone are the main sedimentary microfacies. The underwater distributary channel sandstone are crossed and connected of Chang 4+52 of Yanding delta, anbian delta and wuqi delta and the compartmentation of underwater distributary channels is strong. While with the decrease of the lake basin, the underwater distributary channels are reduce,and the interdistributary extend of chang 4+51. The compartmentation of underwater distributary channels of chang 4+52 is more obviously, and subaqueous distdbutary channel sandstone is thickenss, is the major reservoirs in the study area.
