具有工业价值的油藏与天然气藏都是深深地放埋藏在地下深处的,而且经过了几百万乃至上亿年的地壳活动,这些地下油气藏有的已变得支离破碎,有的被隐藏得更难以发现。为了找到地下深处的油气藏,人们采用了重力勘探、地震勘探和钻井等一系列方法,由于这些都是沿用 Reservoirs and natural gas reservoirs of industrial value are deeply buried deep underground, and after millions or even billions of years of crustal activity, these underground oil and gas reservoirs have become fragmented and some have been Hidden more difficult to find. In order to find subterranean reservoirs, a series of methods such as gravity exploration, seismic exploration and drilling are used, since these are all used
