【摘要】 普光气田是川东北地区最大的气藏之一,是一个受构造和岩性控制的复合圈闭气藏。通过对飞仙关组气藏的岩石学特征、地震反射系数变化特征以及地震响应特征等方面的研究,分析认为飞仙关组一、二段(T1f1-2)储集层物性较好,其地震反射系数比飞三段(T1f3)变化大,"亮点"和"暗点"反射特征表现明显,通过运用地震反射特征进行气田井位部署,应用后取得了较好的效果。更多还原

【Abstract】 The Puguang Gasfield is one of the biggest gas reservoir in northeast Sichuan Basin,and it is controlled by lithology and structures.This paper studies the characteristic of lithology,reflection coefficients and the characteristics of seismic reflection.The results indicate the reservoir characteristics and physical property of T1f1-2 is better,its reflection coefficient is bigger than T1f3,and the characteristics of bright spots and dark spots are obvious in Puguang Gasfield.The effects of deploying wells according to seismic reflections are good.更多还原
