库车坳陷克拉苏构造带发育多个超高压大气田,但是形成和分布复杂。本文在分析克拉苏构造带地质背景的基础上,提出了克拉苏构造带超高压大气田的形成模式和主控因素。克拉苏构造带超高压大气田主要存在3种成藏模式即浅部背斜区带模式——气侵型晚期聚气模式、深部区带模式——气侵型晚期一次聚气模式和特深区带模式——晚期一次聚气模式.克拉苏构造带超高压大气田形成和分布的5个主控因素为生气中心及生气规模、气源岩的晚期快速生气、优质盖层、构造圈闭和超高的流体压力。该成果将对该研究区今后深入研究具有重要的参考价值。
庫車坳陷剋拉囌構造帶髮育多箇超高壓大氣田,但是形成和分佈複雜。本文在分析剋拉囌構造帶地質揹景的基礎上,提齣瞭剋拉囌構造帶超高壓大氣田的形成模式和主控因素。剋拉囌構造帶超高壓大氣田主要存在3種成藏模式即淺部揹斜區帶模式——氣侵型晚期聚氣模式、深部區帶模式——氣侵型晚期一次聚氣模式和特深區帶模式——晚期一次聚氣模式.剋拉囌構造帶超高壓大氣田形成和分佈的5箇主控因素為生氣中心及生氣規模、氣源巖的晚期快速生氣、優質蓋層、構造圈閉和超高的流體壓力。該成果將對該研究區今後深入研究具有重要的參攷價值。

There are many overpressured large gas fields in Kelasu tectonic zone of Kuqa Depression in Tarim basin,and the formation and distribution are complex.Based on the analysis of geological background and formation mechanism,formation model and main controlling factors were put forward.Three kinds of accumulation model exist in the overpressured large gas field,namely anticline zones model,deep zones model and especial deep zones model in Kelasu tectonic zones of Kuqa Depression.The main controlling factors in accumulation of overpressured large gas field are as follows：the location of the gas generating centre and the scale of the gas generation,the quick mature rate,high quality capping rocks,structural trap,and the overpressured fluid.The research achievement will play an important part in the future research of this research area.
