| 摘 要： | 克拉玛依油田八区克下组油藏属山前陆相盆地边缘冲积扇成因砾岩油藏,油藏单一扇体具独立成藏体系。研究中需区分不同扇体,厘清扇体展布及演化特征,为油藏后期精细开发提供依据。在沉积微相特征分析基础上,充分运用砾岩组分和重矿物资料,落实八区克下组发育的3大冲积扇体,发现扇体具明显区带性,自下而上呈退积式演化特征。对油田生产状况分析认为,八区克下组油藏产能及剩余油分布受沉积微相控制,其中主槽和辫流线为最有利相带,具高产特征,是剩余油主要分布区。 |
| 关 键 词： | 砾岩油藏 冲积扇 重矿物 剩余油 沉积微相 |

| Abstract: | Lower Karamay in 8th Zone of Karamay Oilfield conglomerate Reservoir in 8th zone,as a set of flluvial fan sedimentary in piedmont continental basin margin,has the characteristic that one fan has an independent accumulation system,so,dividing different fans and making clear of the distribution and evolution of fans are necessary for latter fine development.Aiming these issues,this study makes full use of the data of conglomerate and heavy mineral to determine the existence of three fans at the base of analysing the characteristic of microfacies,the fans have different rang-zone and their evolution is retrogradation from bottom to top.Finally,connected with the oilfield production status,it is thought that productivity and remaining oil are controlled by microfacies,major trough and braided stream are the favorable microfacies which show high productivity and are the main distributed area of remaining oil. |
| Keywords: | Conglomerate reservoir Fluvial fan Heavy mineral Remaining oil Microfacies |
