【摘要】：长期的油气渗漏会引起地表岩层或土壤发生烃类及其他蚀变异常,这些异常独特的反射光谱特征为利用遥感技术提取油气渗漏相关信息提供了依据。利用航空高光谱SASI数据,结合野外实测光谱,提取新疆吉木萨尔西大龙口地区油气渗漏引起的烃及高岭土化信息。通过研究区遥感地质解译,发现烃信息主要分布在二叠系芦草沟组、梧桐沟组和侏罗系八道湾组内,高岭土化主要集中于三叠系小泉沟群和侏罗系八道湾组内,不整合面和次级断裂是油气渗漏的主要通道,饱和烃质谱色谱分析结果表明油源来自深部的二叠系芦草沟组。根据区域构造演化和地震剖面资料,油气渗漏可能开始于印支晚期,在喜马拉雅期达到顶峰,如今地表形成的油气渗漏主要为喜马拉雅期构造运动的产物,研究区西部油气渗漏烃异常的深部以及阜康—吉木萨尔逆冲断层下盘是下一步油气勘查值得重视的目标区。
[Abstract]:Long-term oil and gas leakage will cause hydrocarbon and other alteration anomalies in the surface rock or soil. These abnormal characteristics of reflectance spectrum provide the basis for extracting the relevant information of oil and gas leakage by remote sensing technology. Based on airborne hyperspectral SASI data and field measurements, hydrocarbon and kaolinization information caused by oil and gas leakage in the West Dalong mouth area of Jimusar, Xinjiang are extracted. Through remote sensing geological interpretation in the study area, it is found that hydrocarbon information is mainly distributed in the Permian Lucaogou formation, Wutonggou formation and Jurassic Badaowan formation, while kaolinization is mainly concentrated in the Triassic Koizumi gully group and Jurassic Badaowan formation. The unconformity surface and secondary fault are the main channels of oil and gas leakage. The results of saturated hydrocarbon mass spectrometry show that the oil source comes from the deep Permian Lucaogou formation. According to the regional tectonic evolution and seismic profile data, the oil and gas leakage may have started in the late Indosinian period and reached its peak in the Himalayan epoch. The oil and gas leakage formed on the surface today is mainly the product of the Himalayan tectonic movement. The depth of hydrocarbon leakage anomaly in the west of the study area and the footwall of Fukang-Jimusar thrust fault are the target areas to be paid attention to in the next step of oil and gas exploration.
