富有成熟生油岩层的油气田及开采区普遍有微量的碳氢化合物逸散到地表,在地层倾斜的油区,这些微油气苗包括液相C10+碳氢化合物在内,不仅扩散到近海地区海底,而且扩散到陆地表面。近海勘探中,天然气从海底逸散产生的气泡是原油界面薄膜非常有效的载体,这样,到达海面的气泡把含油悬浮微粒带进空气中,同时有微量的油迹留在海面,为了探测这种含油悬浮微粒,已经研制了一种名为航空微迹(A1RTRACE)的高灵敏度航测系统,仪器安装在一个低空飞行双引擎短距起落的飞机中,机头装有采集系统,能对大气中的含油悬浮微粒进行百万次以上的采集,不断地从悬浮大气微粒中解吸碳氢化合物并进行分析,以40次/秒
In the oil-gas fields and mining areas of the mature oil-bearing rock formations, trace amounts of hydrocarbons are generally released to the surface. In the stratigraphic inclined oil areas, these micro-oil and gas spills, including liquid C10 + hydrocarbons, not only spread to the offshore of the offshore area, And spread to the surface of the land. In offshore exploration, gas bubbles that escape from the seafloor at the bottom of the sea are very effective carriers of the crude oil interface film so that air bubbles reaching the sea surface carry oil-bearing aerosols into the air while traces of oil remain on the surface of the sea, Oil-bearing aerosols, a highly sensitive aerial survey system called the A1RTRACE, has been developed. The instrument is housed in a low-flying twin-engine aircraft that is equipped with acquisition systems that operate on atmospheric Oil-bearing aerosols were collected millions of times, continuously desorbing hydrocarbons from suspended aerosols and analyzing them at 40 cycles per second
