成岩相是在一定沉积和成岩环境下经历了一定成岩演化阶段的产物,是表征储层性质、类型和优劣的成因性标志。本文针对普光气田礁滩相储层相变快、非均质性强的特点,综合考虑成岩作用特点、孔隙类型、古地貌等进行成岩相的划分,明确了高孔渗带储层形成的主控因素,对气田的开发具有重要指导作用。
Diagenetic facies is a product of some stages of diagenetic evolution in certain sedimentary and diagenetic environments and is a genetic marker for characterizing the nature, type and superiority of reservoirs. In this paper, according to the characteristics of fast reef-facies reservoirs in Puguang gas field and strong heterogeneity, the diagenetic facies are divided into two types according to diagenetic characteristics, pore types and palaeogeomorphology. Control factors, the development of gas fields has an important guiding role.
