准噶尔盆地南缘霍玛吐构造带油气水分布主控因素及其勘探启示

The Main Controlling Factor of Oil-gas-water Distribution and Its Implications in Huomatu Tectonic Zone of Southern Junggar Thrust Belt

针对准噶尔盆地南缘霍玛吐构造带古近系油气藏油气水差异性分布特征,结合前人对该区油气成藏演化研究成果,探讨了该地区油气水分布主要控制因素。研究认为构造转换带、楔形叠加构造样式、有利储层发育与新构造运动下的保存条件是控制霍玛吐构造带油气水差异性分布的4大主要因素。油气水分布主控因素的研究不仅可以为探索霍玛吐构造带复杂油气分布规律提供借鉴,而且还可以对该地区下一步的油气勘探工作有所启示。

In allusion to the characteristics of different distributions of oil-gas-water in Eogene of Huomatu Tectonic Zone and in combination with the predecessorsresearch result of hydrocarbon accumulation and evolution,the major control factors on distribution of oil-gas-water were studied in the area.The study indicates that structural transform zone,superimposed wedge structure,the favorable reservoir development and later preservation conditions controlled by new tectonic movement are four main controlling factors of oil-gas-water distribution.The study of main control factors of oil and gas and water distribution in Huomatu Tectonic Zone provides some references for the research of complex oil and gas distribution law,also gives somewhat enlightenments for the hydrocarbon exploration in the area.
