摘要
简要回顾了上扬子四川盆地震旦系—寒武系特大型天然气田发现历程,指出磨溪—龙王庙气田是中国目前发现地质时代最老、单体构造储量规模最大的大气田,突破发现于近5年间,得益于绵阳—长宁拉张槽的发现。进一步阐述与分析了绵阳—长宁拉张槽的分布位置、边界特征;生烃、储层体系特征;形成演化与油气成藏特征;特别指出了其重大勘探发现及理论研究认识对于推进下扬子海域南黄海盆地油气勘探的重要意义。
We made in this paper a brief review on the history of exploration for large gas fields in the Sinian and Cambrian in the Sichuan Basin of the Upper Yangtze Platform,and concluded that the Moxi-Longwangmiao Gas Field is the oldest and largest gas field ever found so far in China within the past 5years.The success of exploration is owing to the discovery of the Mianyang-Changning Aulacogen.Then we further elaborated the tectonic location,boundary conditions;hydrocarbon generation,reservoir properties,and formation and evolution of hydrocarbon accumulations in the aulacogen.The theoretical and practical researches of the fields are beneficial and helpful to the comparative study of hydrocarbon accumulations in the Lower Yangtze Platform or the South Yellow Sea Basin.
