准噶尔盆地石南地区头屯河组岩性圈闭识别

The Lithologic Traps Recognition of Toatanhe Formation in the Area of Shinan in Janggar Basin

准噶尔盆地腹部石南地区油气藏的形成具有多源、多灶、多期成藏、源外次生的特点。该地区沉积体系复杂，经过多年来的研究，沉积体系的认识尚不统一。本论文着眼于研究区的所有井点，利用井震结合的方法进行研究区头屯河组二段的精细沉积相研究，并结合地震属性分析预测此层位岩性圈闭有利发育区带，分析其岩性圈闭主控因素。最后，优选石南8井北岩性圈闭作为实例，对其储盖组合、成藏条件进行评价。

The formation of reservoirs in the area of Shinan in Central Junggar basin is characterized by multitudes of hydrocarbon sources, multi-stage reservoiring and secondary oil/gas reservoirs. The sedimentary systems are so complex that the conclusion about them have still not been unified. This paper studies the delicate sedimentary facies using the combination of wells and seismic data, based on all the wells in region of intrest and predicts the zones of interest of developing lithologic traps, analyzes the main control factors on Toutunhe formation. The paper also takes the lithologic trap of north of Shinan 8 well for instance to assess the assemblage of reservoir and cap rock and pay condition.
