摘　　要：缝洞体系是碳酸盐岩油气藏勘探的一个重要对象。以往的研究发现断溶体是一种重要的构造缝洞体系。最近我们在研究碳酸盐岩构造缝洞体系时发现了一个新的构造缝洞体系:褶溶体。褶溶体是一种褶皱作用控制下的溶洞裂缝体系。根据褶皱部位可以分为3种褶溶体:1)背斜褶溶体;2)向斜褶溶体;3)翼部褶溶体。背向斜褶溶体与褶皱过程中的虚脱和轴面节理有关;翼部褶溶体与层间滑动和翼部褶断有关。以背斜褶溶体最为重要,因为最易于富集油气,形成缝洞油气藏。褶溶体的形成与岩性、岩层厚度和褶皱的形成过程中的应力状态和岩层破裂过程及古气候、古地理等因素密切相关。An important object of carbonate reservoir exploration is the fracture-cave system.Previous studies have found that fault-cave composite is an important oil and gas reservoirs that have been found in the past study.Recently,a new structural cave system had been found and it was named as fold-cave composite.According to the fold position,it can be divided into three kinds of fold-cave composite:one is anticlinal fold-cave composite;the other is the synclinal fold-cave composite and the third is the flank-cave The fold-cave composite is related to collapse and axial plane joints that are formed during the process of folding.The flank-cave composite is related to the sliding between layers.Anticlinal fold-cave composite is the most important because it is easy to accumulate oil and gas to form reservoir.The formation of fold-cave composite is closely related to lithology,thickness of rock layer,stress state during the formation of fold and fracture process of rock layer.
