【摘要】 非构造圈闭的识别是非构造油气藏勘探的难点,微生物油气调查技术可根据圈闭中富含的油气与其上方地表土壤中的微生物含量的关系来寻找富集于圈闭内的烃类流体,是一种有效的油气勘探技术,应用该技术已在柴达木盆地、Fort Worth盆地、俄克拉荷马州Osage县等多处发现了高产的岩性和复杂构造油气藏。目前该技术还需要在轻烃微渗漏原理、微生物的影响因素、微生物的检测技术、数据的地质解释等4个关键环节继续完善。更多还原

【Abstract】 The exploration of subtle or non-structural reservoir is of great challenge for recognition of its non-structural trap.Microbial oil survey technique (MOST) is effective for such reservoir recognition,for it depends on the relationship between oils in the trap and microbial concentration in soil above it for exploration of hydrocarbon fluid.The successful application of MOST to Qaidam basin,Fort Worth basin and Osage county in Oklahoma shows that high-yielding lithologic and structural reservoirs have been discovered.This paper points out that there is a great need for modification or perfection in such four aspects as light hydrocarbon micro-percolation principle,affecting factor and detecting technology of microbe as well as related geological interpretation.更多还原
