文档介绍：试论隐蔽油气藏的分类及勘探思路沈守文彭大钧颜其彬黄先律摘要: 在前人研究基础上,依据圈闭的隐蔽性、圈闭的成因及形成圈闭的主导因素、圈闭的剖面形态,提出了一个新的隐蔽(圈闭)油气藏分类方案。方案不仅包括了常见的地层岩性油气藏,也包括了古构造油气藏、向斜油气藏、易伤害低渗透油气藏等多种特殊类型。这有利于勘探工作者开阔视野,并在勘探实践中根据不同的隐蔽油气藏类型,采取不同的勘探思路和方法。主题词: 油气藏分类;勘探方法;隐蔽圈闭;地层圈闭;古构造圈闭; 向斜油气藏中图分类号: TE112 文献标识码: A 文章编号: 0253-2697(2000)01-0016-07 CLASSIFICATION AND EXPLORATION METHODS OF SUBTLE TRAP RESERVOIRS SHEN Show-wen etal.(Southwest Petroleum Institute) According tothe degree ofconcealment, the main origin type and the profile form ofhydrocarbon traps, anew classification for subtle traps has been made onthe basis ofpredecessors work. Itincludes not only stratigraphic and lithologic reservoirs, but also paleo-structure trap reservoirs, syncline reservoirs and low permeability reservoirs being susceptible todamage, etc.. Itis helpful for petroleum explorationist toexpand research fields and toapply different methods bydifferent types ofsubtle traps in hydrocarbon exploration. Key words: reservoir classification; exploration method; subtle trap; stratigraphic trap; paleo-structure trap; syncline reservoir 1 隐蔽圈闭的概念及其由来隐蔽圈闭(subtle trap) 一词较早见于莱复生()196 4 年的论文,是用来称呼构造、地层、流体(水动力)多要素结合的复合圈闭。 1966 年他在遗著中以隐蔽和难以捉摸的圈闭(the obscure and subtle trap) 为题,全面论述了对隐蔽(subtle trap) 的新认识,表示“subtle trap ”与早期所用的复合圈闭(combination trap) 有所区别。 bination trap ”这一术语具有确定的含义,在石油地质文献中已广泛流传,完全可以用来表示多要素结合的复合圈闭,而subtle tra p 本身因缺乏严格的含义而未能广泛使用[1]。直到197 2年哈尔鲍蒂(
