摘　　要：准噶尔盆地石南油气田地表为沙漠,地震激发接收条件较差,导致其资料品质差,并且储层砂体厚度较薄,横向变化非常复杂,难以进行砂体的精细描述。为了弄清砂体的空间展布,运用地震沉积学的原理和方法,井震结合建立精细层序地层格架,确定了头屯河组的砂体形态、规模以及其尖灭线位置,明确了三角洲沉积微相与砂体几何形态的关系,依据砂体空间叠置样式建立了地质概念模型,为今后的油气田勘探开发奠定了良好的基础。The seismic signal shooting-receiving conditions are poor in Zhunggar Basin of Shinan Oilfield,therefore resulting in poor data quality due to the desert on the ground of the area and the delicate description of oil sand bodies is difficult due to the small thickness of oil sand bodies and complex lateral variation.In order to clarify the spatial distribution of the oil sand bodies,by using the principle and methods of seismic sedimentology and seismic-well combination,the delicate sequence stratigraphy framework is established,the shape of the sand bodies,scale and pinch-out position of Touhetun Formation are determined and the relationship between the sedimentary micro-facies of the delta and the geometry shape of the sand bodies are determined.Based on the spatial superposition mode of the sand bodies the geology concept model is established,setting up a good foundation for future exploration and development of the oil field.
