摘要：

地下水液液是传递深部油气信息的媒体,压差和温差是传递深部信息的动力,地表的土壤是深部信息的载体。油气地球化学和含水量的分析表明,油气微渗漏蚀变晕的遥感信息是油气相关组份和无机组份的综合反映,其中含水量较背景值显着增高的现象具有普遍意义。导油导气构造,以张性破碎带为主,遥感图像上呈现为一条贫水的浅色带;以压性或压扭性构造或粘土层为主要封闭型的含油气构造,遥感图像上呈现为一条富水的深色带。因此,提取油气信息必须选择地面湿度适中的时相,同时注意气象因素。

Abstract:

Underground water solution is the medium of deep oil gas information.The occurrence of pressure difference and temperature difference is the dynamics for the transission of deep seated information.The analyses made in hydrocarbon geochemics and water content show that remote sensing information of the alteration halo of oil gas microseepage could be considered as the comprehensive reflector of both organic and inorganic components.It is common that water content in alteration halo is considerably higher than background value.Structures of oil and gas passages are mainly closed extensional structures which appear to be light colour zones with low water content in remote sensing images;oil gas bearing structures sealed by compressional or transpressional structures and clay beds appeared to be dark zones with high content of water in the images.It is suggested that to extract oil gas information,one should choose suitable humidity and also consider mteorologic factor.
