The achievements of exploration and development in recent years indicate that there exists good condition of natural gas accumulation in the PY-LH zone in Zhujiang River Mouth basin as an important zone for gas exploration,including plenty gas source,fine reservoir-sealing assemblage,good trap conditions and composite transport system.The gas accumulation is summed as follows: later accumulation,single type of gas reservoir.Vertically,natural gas mainly accumulates in the low section of Zhujiang Formation.Laterally,natural gas has a banding distribution along the northeast direction.Based on correlation between forming conditions and distribution of gas reservoirs,natural gas in the PY-LH zone is mainly co-controlled by structure ridge,matching condition between traps and reservoir-cap assemblage,sealing and preservation conditions.
