摘要
Changxing Formation in Yuanba gas field are researched and following characteristics are concluded.First,the rock types are dominantly sparry bioclastic limestone and sparry bioclastic dolomite,with higher dolomite content in the west reel-shoal reservoir than in the east,and higher in Chang2 member than in Chang1 shoal reservoir.Second,the reservoir types are dominantly pore type,with fracture-pore type for the second.Third,the reservoir is mainly type Ⅱ and Ⅲ,with physical properties better in the west than in the east,and reservoir much thicker in Chang2 than in Chang1.The reservoir of Changxing Formation in Yuanba area was controlled by sedimentary facies,tectonic movement and diagenesis,and affected by the double action of predeposit palaeogeomorphology and post-Yanshanian movement.
