葡萄花油层高分辨率层序地层划分及沉积微相研究
|
摘要
应用岩心、测井、地震等资料,以高分辨率层序地层学原理为指导,并结合陆相湖盆层序地层特征,将他拉哈-常家围子地区葡萄花油层划分为1个长期基准面旋回,5个中期基准面旋回,25个短期基准面旋回,建立起该区葡萄花油层高分辨率层序地层格架。在岩心、测井曲线综合分析的基础上建立了该区测井相模式,并绘制相应沉积微相图。平面垂向相序及砂地比等值线图揭示他拉哈-常家围子地区主要受两个物源控制,西部近物源和东北部远物源。分流河道和席状砂为有利储层,砂体展布形态主要受控于物源远近及古地貌形态。
Using core and well logging and seismic data,with high-resolution sequence stratigraphy principle as a guide,and combined with continental sequence stratigraphic characteristic,Putaohua reservoir in Talaha-Changjiaweizi area of Songliao basin was divided into 1 long-term base level cycle and then subdivided into 5 medium-term base level cycle and 25 short-term base level cycle,and sequence stratigraphic framework are set up.Based on comprehensive analysis of the core and well log log facies patterns of the area are eslablished and the corresponding microfacies map are dram.The vertical sequence of microfacies and percentage of sand in formation reveals that the region is mainly affected by two provenance,the near provenance from west and the far provenance from northeast.Channel and sheet sand are sweet reservoir.Distribution of sand is controlled by provenance distance and palaeogeomorphology.
