摘要:
通过对钻井岩心的岩石学特征、沉积构造及岩相分析,结合测井相标志和古生物标志,对盒8段的沉积微相特征盒8段沉积微相特征进行了详细研究。结果表明,召41井区盒8段为辫状河三角洲平原亚相沉积,并进一步划分出分流河道与泛滥平原微相,其中广泛发育的分流河道是其沉积主体,由于河道不断迁移,垂向上多期砂体互相叠置为巨厚砂体并与泛滥平原沉积交替出现。侧向上单砂体呈透镜状展布,多期叠加为厚砂体延伸较远。研究表明盒8段主要沉积微相为辫状河三角洲平原分流河道,砂体在平面上展布为近南北向,连片性好,纵向上多期河道砂体互相叠置,延伸较远,是天然气储集的有利场所。沉积微相及有利储集相带的研究为该区块含气有利区预测及开发井位部署奠定了基础。
Abstract:
Through analyzing core of petrology characteristics,sedimenttary structures and petrographic facies,combining with log facies marks and paleontology in Zhao 41 Area,southeast of Sulige,a detailed research on sedimentary microfacies of He 8 section has been carried out.The results suggest:The sedimentary system of He 8 section in Zhao 41 Area is braided river delta plain sedimentary subfacies,further divided into distributary channel and flood plain microfacies,the extensive development of distributary channel is the sedimentary body,due to the channel migration,vertical multiphase sand bodies superimposed with each other for the thick sand bodies and the flood plain deposits appear alternately.On a single lateral distributary channel sand body distribution is lens,multiphase superposition of thick sand body with extension farther.Conclusion:The main sedimentary microfacies of He 8 Section is braided river delta plain distributary channel,and sand bodies are nearly NS-trending distribution and good flat piece,multiphase channel sand bodies on the vertical superimposed have good lateral continuity.Research of sedimentary facies and favorable reservoir facies belts laid a good foundation for predicting favorable gas areas and well deployment.
