摘　　要：瘤状灰岩是一种较常见的具有瘤状形态及相似产出特征的碳酸盐岩,由瘤体和基质两部分组成。瘤状灰岩的颜色多样,形态各异,含有多种生物碎屑,岩层中发育缝合线构造和一些张性裂缝,不仅可成为油气运移的通道,也可成为油气的储集空间。通过对瘤状灰岩相关文献的查阅,总结了瘤状灰岩在我国的分布、分类、特征及成因、意义。Nodular limestone is one of the more common with nodular form and similar to the output characteristics of carbonate rocks, consists of two parts, tumors and the substrate. Nodular limestone has variety of colors and forms, contains a lot of bioclastic, the rocks development suture line structure and some tensile cracks, these not only can be channels of hydrocarbon migration, also can become the oil and gas reservoir space. This article through to consult the relevant literature of nodular limestone, summarized the distribution of nodular limestone in our country, the classification, the classification and the causes, the significance of nodular limestone.
