摘要:
针对准噶尔盆地边缘复杂的冲积扇沉积体系,利用密井网及露头资料,采用层次界面分析,对冲积扇储集层内部构型分级次解剖,建立了盆地西北缘红18井区克拉玛依组克下亚组冲积扇储集层的构型样式及三维构型模型。冲积扇沉积体4级构型由槽流砂砾岩体、片流砾石体、高能水道砂体、低能水道砂体及径流水道砂体等组成,同时包括漫洪砂体、漫流砂体及漫洪细粒沉积等非优质储集层。冲积扇不同相带内部构型存在差异,槽流—片流相带为复杂砂砾岩体叠置形成的席状连通砂砾岩体,单一砂砾岩体宽1.2~1.6 km;辫流相带为高能水道砂体、低能水道砂体与漫流砂体的复杂叠置,其中高能水道宽度为400~600 m,低能水道宽度为100~250 m;径流相带呈镶嵌状分布在漫溢细粒沉积中,为孤立窄条带状,单一径流水道宽度为50~80 m. 在精细地质研究基础上,利用确定性建模结合人工互动方式,建立了研究区的三维构型模型。
Abstract:
Regarding the complicated sedimentary system of alluvial fans located in the margin of Junggar basin, with the data of well patterns and outcrops and using the method of hierarchical bounding surface analysis, the paper performs a leveled dissection on the internal architecture of alluvial fan reservoirs and establishes the reservoir architecture patterns and 3D geologic models for alluvial fans of the lower Karamay formation in the Wellblock Hong-18 of the northwestern margin of the basin. The 4-order architecture of the alluvial-fan sedimentary system is made up of trench-flow sandy conglomerate, laminar-flow gravel, high-energy channel sandbody, low-energy channel sandbody and runoff channel sandbody, meanwhile, it includes some low-quality reservoirs such as flood sandbody, sheet-flood sandbody and fine-grained flood deposit. The internal architectures of different facies belts in the alluvial fans are different. Trench flow-laminar flow facies belts are dominated by connected sheet sandy conglomerate which is the product of the superimposition of complicated sandy conglomerate and a single sandy conglomerate body is 1.2~1.6 km wide; the braided-flow facies belt is the complex superposition of the high-energy channel sandbody, low-energy channel sandbody and sheet-flood sandbody, among which the high-energy channel is 400~600 m wide and the low-energy channel is 100~250 m wide; the runoff channel belt is distributed in the fine overbank deposits in the shape of mosaics and shows an isolated narrow strip shape, and the width of a single runoff channel ranges from 50 m to 80 m. Based on the detailed geological research, the paper establishes 3D architecture models for the study area by using deterministic modeling combined with artificial interactive methods
