摘要
普光气田是一个储量规模大、埋藏深、资源丰度高的整装海相气田。气田发现于2003年,至2005年底累计探明储量2510.7×108m3。普光背斜构造的气藏圈闭面积为45.6km2,主要含气层段为下三叠统飞仙关组及上二叠统长兴组礁滩相白云岩。烃源岩为下志留统龙马溪组和上二叠统龙潭组泥岩和页岩。论述了气田的发现和勘探过程及气藏的基本地质特征,总结了它对我国碳酸盐岩和成熟盆地油气勘探的启示。
Puguang Gas Field was discovered in 2003 in Sichuan Basin. it is the gas field that has the largest scale of reserves, the largest buried depth and highest reserves abundance. Till to the end of 2005, it has the proved gas reserves in-place of 251.07×10^9m^3 and the gas trap in Dongyuzai-Puguang anticline covers an area of 45.6km^2. Main gas-bearing reservoirs are Lower Triassic Feixianduan and Upper Permian Changxing reef-shoal facies dolostone, Hydrocarbon derived from Lower Silurian Longmaxi and Upper Permian Longtan sandy mudstone and shale. The discovery and exploration history of the field, geological characteristics of the gas reservoir and the exploration revelation to the carbonate reservoirs are revealed.
