摘要 高效气源灶(包括分散可溶有机质裂解型高效气源灶和古油藏裂解型高效气源灶)、高效的成藏过程和优质要素有效组合是天然气高效成藏的核心内容。主要阐述了高效气源灶概念与评价方法、高—过成熟阶段有机质接力成气机理、高效成藏过程的(半)定量评价指标以及三大要素耦合控藏等认识。并依据这三个有效性,评价了我国的高效天然气资源。这些进展,丰富和发展了中国天然气地质理论,对拓展天然气勘探领域,指导高效气藏的勘探有着重要的意义。 It is presented that the nuclear ideas of high-efficiency gas accumulation include two kinds of high-efficiency gas kitchen (i.e. the cracking gas source kitchen of dispersive dissoluble organic matter and paleo-oil accumulation), high-efficiency gas accumulation, and effective assemblage by high-grade factors. The knowledge on studying high-efficiency gas accumulation involves the concept and the evaluation method about high-efficiency gas kitchen, the mechanism of successive organic gas at the over-mature period, half quantitatively evaluation indexes during the high-efficiency gas accumulation process, and gas accumulation controlled by three factors coupling action, and so on. High-efficiency gas resource has been assessed based on these nuclear ideas. This case of study will enrich and develop Chinese gas geology, while developing new areas for natural gas exploration, which guides the exploration helpfully for much more high-efficiency gas resource.
