【摘要】：長期的油氣滲漏會引起地表巖層或土壤發(fā)生烴類及其他蝕變異常,這些異常獨特的反射光譜特征為利用遙感技術(shù)提取油氣滲漏相關(guān)信息提供了依據(jù)。利用航空高光譜SASI數(shù)據(jù),結(jié)合野外實測光譜,提取新疆吉木薩爾西大龍口地區(qū)油氣滲漏引起的烴及高嶺土化信息。通過研究區(qū)遙感地質(zhì)解譯,發(fā)現(xiàn)烴信息主要分布在二疊系蘆草溝組、梧桐溝組和侏羅系八道灣組內(nèi),高嶺土化主要集中于三疊系小泉溝群和侏羅系八道灣組內(nèi),不整合面和次級斷裂是油氣滲漏的主要通道,飽和烴質(zhì)譜色譜分析結(jié)果表明油源來自深部的二疊系蘆草溝組。根據(jù)區(qū)域構(gòu)造演化和地震剖面資料,油氣滲漏可能開始于印支晚期,在喜馬拉雅期達到頂峰,如今地表形成的油氣滲漏主要為喜馬拉雅期構(gòu)造運動的產(chǎn)物,研究區(qū)西部油氣滲漏烴異常的深部以及阜康—吉木薩爾逆沖斷層下盤是下一步油氣勘查值得重視的目標區(qū)。
[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.
