【摘要】：准噶尔盆地哈拉阿拉特山地区中二叠统夏子街组为近物源扇三角洲沉积,其纵向切割叠置,厚度大,沉积格局复杂。通过精细研究对比发现,哈拉阿拉特山西部及东部地区虽都发育扇三角洲沉积,但在相标志、搬运机制、砂体特征等方面存在明显的差异。综合岩心、测录井等多种资料,运用沉积特征及岩电分析等手段研究后认为,西部地区为陡坡重力流为主的靠山型扇三角洲,东部地区为缓坡牵引流为主的靠扇型扇三角洲,2种不同类型的扇三角洲具有不同的储集层物性及储集层分布格局。这一认识对油气的勘探具有一定的指导意义。
[Abstract]:The Xiazijie formation of the Middle Permian in the Hara Arrate Mountain area, Junggar Basin, is a near-provenance fan delta deposit, whose longitudinal cutting is superimposed, its thickness is large, and the sedimentary pattern is complex. It is found that although fan delta deposits are developed in Shanxi part and eastern part of Hara Arrate, there are obvious differences in facies markers, transport mechanism, sand body characteristics and so on. Based on the study of core, logging and other data, and by means of sedimentary characteristics and geoelectric analysis, it is concluded that the western region is a backhill fan delta dominated by gravity flow on steep slopes. There are two different fan deltas with different reservoir physical properties and reservoir distribution patterns in eastern China, which are dominated by gentle slope traction flow. This understanding has certain guiding significance for oil and gas exploration.
