摘要
准噶尔盆地庄1井区下侏罗统三工河组二段砂体是重要的油气储集体,明确该套砂体的成因,建立该区的沉积相模式,对于该区的进一步勘探有重要指导意义。目前对此套砂体成因的认识不一。通过对庄1井区的岩心、岩相、岩相组合的细致分析,认为J1s21(下侏罗统三工河组二段上亚段)主要为曲流河三角洲前缘沉积,而J1s22(下侏罗统三工河组二段下亚段)主要为辫状河三角洲前缘沉积,且夹有滑塌浊流沉积。
Sandbodies of Member 2 of Lower Jurassic Sangonghe Formation are the important reservoirs in the Junggar Basin. At present, there are different understandings to the sandbodies. Understanding the origin of the sandbodies and establishing a sedimentary facies model of the area will shed light on the petroleum exploration and development. The analysis of the core, lithofacies and lithofacies sequence of the wells around Well Zhuang 1 indicates that J1s2^1 (the Upper Second Member of Sangonghe Formation of the Lower Jurassic) belongs to the deposition of meandering stream deltaic front; J1s2^2 (the Lower Second Member of Sangonghe Formation of the Lower Jurassic) belongs to the deposition of braided stream deltaic front and is with the slump turbidite facies at the front of it.
