摘    要:和什托洛盖盆地为准噶尔西北缘大型逆冲褶皱带的一个早中生代盆地,油气地质特征复杂.应用成盆动力学及盆山耦合系统的理论对盆地进行系统的构造解析,并利用平衡剖面技术全面解剖和什托洛盖盆地的构造演化特征.同时,深入分析和探讨了不同阶段构造演化过程对油气运聚成藏的控制和影响作用.在此基础上,获得了以下重要结论与认识:(1)和什托洛盖盆地的构造演化与准噶尔盆地西北缘和哈拉阿拉特山有着密切关系,大致经历了3个演化阶段,即盆地雏形阶段(C-T)、盆地主要发育阶段(J-K)和盆地改造阶段(E-Q);(2)和什托洛盖盆地的烃源岩、储集层、盖层及圈闭均较发育,断裂和区域性不整合面为油气运移创造了良好的条件;(3)目前应以盆地西部为重要靶区,同时加强对于侏罗系低成熟气、煤成气生成的综合研究.

关 键 词:和什托洛盖盆地  盆山耦合理论  构造演化  平衡剖面技术  油气成藏  新疆

Abstract:The Heshituoluogai Basin is an Early Mesozoic basin in the large thrust fold belt in northwest Junggar,Xinjiang.Applying basin dynamics theory,basin-range coupling idea and balanced cross section technique,this paper shows the complete structural interpretation and resumes the tectonic evolution of the basin area.The controls and influences of the tectonic evolution on the migration and accumulation of oil and gas in the area are also analyzed and discussed.On this basis,it is concluded that: 1) The tectonic evolution in the area of Heshituoluogai Basin,closely related to the northwest Junggar Basin and Hala,alate Mountain,can be divided into prototype stage(C-T),major development stage(J-K) and reconstruction stage(E-Q);2) The Heshituoluogai basin,with fairly good hydrocarbon source rock,many reservoir-seal assemblages,different types of traps,faults and regional unconformities,has good conditions for oil and gas migration;3) The western basin should be the key target,where comprehensive studies on Jurassic low-mature gas and coal-formed gas could be strengthen.
Keywords:Heshituoluogai Basin  basin-range coupling theory  tectonic evolution  balanced cross section technique  hydrocarbon accumulation  Xinjiang
