| 摘 要： | 川口油田川46井区长4+5、长6各含油层段构造面貌主要为西倾单斜形态,构造特点在宏观上控制了沉积作用,沉积作用在很大程度上反映或影响着构造特征。通过测井相识别进一步证实川口油田长4+5、长6储层以三角洲前缘、平原沉积为主,主要沉积微相为水下分流河道、河道砂坝、分流间湾、决口扇等,在平面和纵向上掌握了其分布特征及演化规律。

| Abstract: | Through sedimentary facies characteristics study,the research finds that Chang 4 + 5 and Chang 6 oil-bearing lay-ers of Chuan 46 block in Chuankou oilfield displays unicline form in western-leaning,and the deposition is controlled by structural features and the structural features affect or reflect the deposition in a large degree as well. Through electrofa-cies recognition,the main sedimentary facies of oil-bearing layers have been confirmed: delta front and plain; the major sedimentary microfacies are: un... |
