摘　　要：对四川盆地充西气田须四段气藏的烃源条件、储层特征、古今构造特征、裂缝特征以及各成藏要素匹配等进行了系统研究。通过这些特征综合分析,认为古今构造条件、储层和裂缝是须四段气藏最终成藏的关键,须四段气藏在古今构造背景下主要受烃源、储层、断层及裂缝发育程度的控制,进而指出发育的储层+裂缝+有利的古今构造叠合地区为天然气富集成藏的最有利地区。The relationships among reservoir-forming factors such as source conditions,reservoir characteristics,palaeo and present structural properties,fractures features in Xujiahe 4 Member of Chongxi gasfield are studied systematically.By the comprehensive analysis,it is considered that the palaeo and present structural conditions,reservoirs and fractures are the keys of forming the Xujiahe 4 Member gas reservoir.This reservoir is controlled by source rock,reservoirs,faults and fractures development under the conditions of palaeo and present structural background.It is further showed the most favorable region of gas accumulation to from the reservoir is superimposed region which is characterized by developed reservoir and fractures along with favorable palaeo and present structures.
