大庆长垣以东裕民地区扶余油层沉积相研究
|
摘要
沉积相分析是研究沉积砂体分布的关键技术。从区域地质背景出发,充分利用大量的岩心、录井、测井、地震及粒度分析等资料,研究结果认为裕民地区扶余油层主要为三角洲平原和三角洲前缘亚相沉积。绘制了扶余油层17个小层沉积微相平面分布图。分流河道沉积砂体呈南西-北东向展布,由南西向北东逐渐减薄,受河道频繁摆动和多期河道叠置切割影响,河道砂体呈复杂条带状或指状。FII2小层以上的分流河道砂体是研究区主要的油气聚集体,为今后勘探和开发提供了重要依据。
Sedimentary facies analysis is the key technology for depositional sand distribution.Based on the regional geological background,large number of coring data,logging and seismic data,particle size analysis,delta plain and delta front deposits subfaces are identified of Fuyu oil layers in Yumin area.17 small layer plane distribution of sedimentary facies of the Fuyu oil layers is Drawed.The distributary channel sand body is deposited in SW-NE trending,thinning gradually from SW to NE,it is complex banded-like and finger-like sand,affected by frequent river swing and overlay multi-cutting of river.Distributary channel sand bodies of above FII2 small layer is best reservoirs,which is key evidence for exploration and development in the future.
