Yinggehai Basin Gas Exploration： Comparison with Jiyang Depression

Yinggehai（莺歌海） basin and Jiyang（济阳） depression experienced similar tectonic evo-lution,which is mainly controlled by the strike-slip faults.The strike pull-apart basins are characteris-tic by multiple deposition cycles,migration of deposition and subsidence center,and diversity deposi-tional systems...

Summary:Yinggehai（莺歌海） basin and Jiyang（济阳） depression experienced similar tectonic evo-lution,which is mainly controlled by the strike-slip faults.The strike pull-apart basins are characteris-tic by multiple deposition cycles,migration of deposition and subsidence center,and diversity deposi-tional systems.Furthermore,both basins show abnormal formation pressure.Compared with the oil and gas-rich Jiyang depression,Yinggehai basin developed the similar geological background that is favorable to the formation of funnel-shaped meshwork-carpet subtle reservoirs.Overpressure diapir body is the core of hydrocarbon accumulation in central diaper zone of Yinggehai basin.Driven by high pressure,oil and gas migrate along the funnel-shaped passage system into the overlying low-potential zone formed.The overlying sand bodies of overpressure diapirs are the favorable gas exploration zone.
