| 摘要: |
| 通过岩芯观察、薄片鉴定、测井和录井资料分析,认为准噶尔盆地西北缘乌尔禾鼻隆地区三叠系百口泉组和克拉玛依组主要发育砂砾岩、砾岩、砂质砾岩及少量砂岩、泥岩;该区的储层以低孔低渗为主,在克拉玛依组可见到少量中孔中渗储层;通过单井沉积相、剖面沉积相研究,结合研究区的构造背景和沉积环境,认为研究区物源以其西部黄羊泉以西地区为主,北部哈拉阿拉特山为辅;百口泉组发育冲积扇沉积,克拉玛依组发育扇三角洲沉积,沉积环境控制了研究区优质储层的分布。 |

| Abstract: |
| The Baikouquan and Karamay Formations within the Urho uplift on the northwestern margin of the Junggar Basin are composed dominantly of glutenite, conglomerate and sandy conglomerate, with subordinate sandstone and mudstone based on the cores, thin sections and well logs. The hydrocarbon reservoirs in this area are dominated by the low-porosity and low-permeability reservoirs, locally by the moderate-porosity and moderate-permeability reservoirs in the Karamay Formation. The principal source of detritus lay to the areas west to the Huangyangquan in the west, and Hala'alate Mountains in the north. The alluvial fan deposits in the Baikouquan Formation and fan delta deposits in the Karamay Formation constitute the excellent hydrocarbon reservoirs in the study area. |
