摘要/Abstract

摘要： 详细地研究了天然气成藏与分布规律后指出，中国天然气聚集与分布具有旋回性、序列性、平衡性、溯源性和多期性的特点，即每一个大地构造沉积旋回为一个天然气成藏系统，每个系统内天然气生成-运移-聚集-成藏表现为一定系列，聚集成藏的重要因素是运移动力与阻力达到平衡，离烃源岩越近聚集效率越高，在漫长的地质历史中具多期成藏特征。大气田的形成与分布受5种特性控制，烃源岩内及紧邻源岩地区、不整合带和断裂背斜带是大气田分布有利地区，除现今发现较多的不整合带和断裂背斜带外，源内和近源地区应是未来重要勘探区域。鄂尔多斯盆地东南部石炭系—二叠系、四川盆地西南部三叠系、库车坳陷北段侏罗系等区带是下一步勘探天然气的重点。

Abstract: The in?depth research in this paper indicates that the accumulation and distribution of natural gas is characterized by cylicity, sequentiality, balance, traceability and multiphase, namely each tectonic sedimentary cycle signifies one gas accumulation system; in each system the generation, migration, accumulation of natural gas are characterized by a certain series; the significant factor for gas accumulation is the balance between migration force and resistance; the closer the distance from hydrocarbon source rocks, the higher the gas accumulation efficiency is, so the multiphase accumulation of gas is its feature in the long geological history. A large gas field is generally controlled by five features in its forming and distribution. The inner hydrocarbon source rocks and adjacent to the source rock area, unconformity zones and faulted anticlinal belts are favorable areas for large gas fields distribution. In addition to unconformity zones and faulted anticlinal belts that have been found more like these nowadays, the inner source area and proximal realm should be the domains for petroleum exploration in the future. The Carboniferous-Permian in southeastern Ordos basin, the Triassic in southwestern Sichuan basin and the Jurassic in Kuqa depression of Tarim basin which haven’t got a major breakthrough could be the significant plays for next exploration of petroleum
