准噶尔盆地W井区西山窑组沉积微相类型及沉积演化模式

Sedimentary Microfacies Types and Sedimentary Evolution Model of the Xishanyao Formation in the West Shixi Oilfield of Junggar Basin

在沉积学、储层地质学、石油地质学等相关理论的指导下,在了解盆地和研究区构造发育特征和沉积背景的前提下,综合运用岩心、薄片、分析化验、测井、录井等资料,对西山窑组进行地层的划分与对比;建立沉积相标志,进行单井相和连井相综合分析,分析沉积相类型和砂体的横向展布规律;对物源进行分析,研究沉积微相的平面展布特征,建立了适用于该研究区沉积演化模式.

Based on the sedimentology,reservoir geology,petroleum geology theory,on the premise of understandingthe tectonic of the basin and sedimentary characteristics of the study area,we made a comprehensive use of core,thin section,analysis,logging,and logging data,to divide and compare the strata in Xishanyao Formation. We establishedof sedimentary facies marks,analyze the single well facies and well-connecting facies,and analyze with the type ofsedimentary facies and horizontal distribution of sand bodies. The sedimentary evolution model is established.
