油气资源的遥感勘探,可分为“直接”和“间接”两大类。红外遥感油气资源勘探技术属于“直接”勘探范畴。本研究基于工业油气藏烃类微渗漏理论,利用烃类特有的2.27—2.46μm波谱双峰吸收带,以土壤烃组分异常为标志实施探测,并从理论上排除了各种地物目标的干扰,建立了一套航空遥感计算机图像处理及油气遥感信息异常提取方法。三次大面积试验表明,与已知油流区块的符合率达70％,在未知区的油气遥感异常中,一些已被钻探证实含有油气性,业已正式列入油气勘探生产计划。
Remote sensing exploration of oil and gas resources can be divided into “direct” and “indirect” two categories. Infrared remote sensing oil and gas exploration technology belongs to the category of “direct” exploration. Based on the theory of hydrocarbon microleakage in industrial oil and gas reservoirs, this study utilized the bimodal absorption band of 2.27-2.46μm, which is peculiar to hydrocarbons, to detect the hydrocarbon component anomaly in soil, and theoretically excluded the targets Interference, set up a set of aviation remote sensing computer image processing and oil and gas remote sensing information anomaly extraction method. Three large-scale tests show that the coincidence rate with known oil flow blocks reaches 70%. Some of the oil and gas remote sensing anomalies in the unknown area have been proved to contain oil and gas by drilling and have been formally included in the oil and gas exploration and production plan.
