Abstract: This paper gives four steps to find oil with landsat TM image:"what?","why?","remote sensing expression","oil-gas prediction" and a study of these methods.The exploration method of remote sensing is very successful,because the remote-sensing technique is synthetic,general,macroscopic and visual.Remote sensing technique is advantageous in the plain area covered by thick vegetation.Remote-sensing information is able to prevent arbitrariness in oil-gas exploration with the oil-gas prediction model to increase the success rate and to reduce the prospecting cost.

摘要： 本文给出卫星TM影像构造找油的四个步骤:“是什么”、“为什么”、“遥感表现”和“油气预测”及其研究方法;指出正是遥感技术的综合性、概括性、宏观性、直观性的特点使遥感构造找油成为一种有效的油气勘探方法,并在巨厚覆盖的平原地区显示出遥感技术的优越性;遥感信息在油气预测模型中的先导作用可减少油气勘探的盲目性、提高命中率和降低成本.
