根据相对海平面升降速率与礁生长速率之间的关系，中国南方二叠纪生物礁可划分为三种类型∶退积礁、并进礁和进积礁。不同类型的礁有其特有的成岩、成藏模式。首先，相对海平面升降控制了礁储集体的非均质性，这种非均质性又控制着原油在礁体内的时空展布，搞清这种时空展布规律对礁油气藏勘探极为重要；其次，相对海平面升降控制着礁含油气系统要素的形成机理及空间配置关系，对礁的含油气系统进行分析可在钻前对礁的含油气潜力作出初步评价。不同类型的礁体群均具有各自不同的成因联系及时空迁移规律，分析这种成因联系及时空迁移规律使我们可以更加准确预测潜伏礁体。
According to the relationship between the relative sea-level lift rate and reef growth rate, the Permian reefs in southern China can be divided into three types: reefs, reefs and reefs. Different types of reefs have their own unique diagenesis and reservoir forming patterns. First, the relative sea-level rise and fall control the heterogeneity of reef reservoirs, which in turn controls the spatiotemporal distribution of crude oil within the reef. It is very important to understand the spatiotemporal distribution of the reefs. Secondly, the relative sea-level rise and fall control the formation mechanism and the spatial distribution of reef petroleum-bearing system elements. Analyzing the petroleum system of the reef can preliminarily evaluate the hydrocarbon-bearing potential of the reef before drilling. Different types of reef groups have their own different causal relations and temporal and spatial migration rules. Analyzing this causation and the laws of temporal and spatial migration make it possible to predict the potential reefs more accurately.
