摘要
鄂尔多斯盆地南部近年来致密油取得较好的试油效果。为明确盆地南部致密油所处沉积微相特征,本文经过资料分析,从区域资料分析入手,进行沉积微相识别,预测沉积微相在平面的展布特征,结合生产实际,得出:盆地南部四个区域中,富县、黄陵、旬邑致密油最有利沉积微相为水下分流河道深水砂岩沉积,发育细砂岩,结构与成分成熟度均较低;甘泉地区致密油除水下分流河道外,浊积水道也为致密油优势微相。
In recent years,the south of Ordos basin has achieved good oil testing effect for tight oil.In order to determine the sedimentary microfacies characteristics of tight oil in the south of the basin,in this paper,from the regional data analysis,to identify the sedimentary microfacies,prediction of sedimentary microfacies in the plane distribution characteristics.Combining with the actual production,it is concluded that,in the southern four regions of the basin,the most favorable sedimentary microfacies of Fuxian,Huangling,Xunyi tight oil is the underwater distributary channel deep-water sandstone deposits,development of fine sandstone,structure and component maturity are low.In addition to the turbidite channel is also the dominant microfacies of tight oil in Ganquan area.
