摘要
油气化探技术具有的可靠性、适应性、灵活性、经济性、连续性等特点,保证了它在隐蔽油气藏勘探中能够发挥非常好的辅助作用。双河、任丘、安塞油田等实例说明隐蔽油气藏近地表地球化学响应明显,并具有明确的地质意义,在隐蔽油气藏勘探中,油气化探技术对发现隐蔽油气藏、指引地震勘探目标、圈定油气藏范围、评价圈闭含油气性、判别流体属性等都可以起到导向性作用。
Abstract
Geochemical prospecting techniques, with the advantages of high reliability,adaptability,flexibility,economy and continuity,can play an important auxiliary role in exploration of subtle oil/gas reservoirs.Examples,such as Shuanghe,Renqiu and Ansai oilfields,show that near-surface geochemical responses are strong in subtle oil and gas reservoirs and have explicit geological significances.Geochemical prospecting techniques can be used to discover subtle oil/gas reservoirs,guide seismic prospecting, delineate limits of oil/gas reservoirs,evaluate oil/gas shows in the trap and discriminate fluid attributes.
