摘要
气聚集带系指成因联系紧密、分布彼此毗邻、受相似地质因素控制的若干气田的组合体。同一类型的或两种类型的相邻的若干气聚集带有规律的组合则形成气聚集区。可以根据地质主要控制因素、气的类型、气源岩和储气层系关系、储气层系纵向上多少等不同原则,对气聚集带进行分类。气聚集带研究在天然气勘探上具有重大作用,因为含气盆地或地区中的大约90％气田分布在气聚集带上。目前世界上发现的所有大气田,几乎均在气聚集带上。因此,研究气聚集带不仅在理论上有重要意义,同时也可以提高天然气勘探的效益。
Gas accumulation zone is a combination of several nearby gas field controlled by similar geological conditions. Several nearby gas accumulation zone of same type or different types regularly combined may form a gas accumulation region. Gas accumulation zone can be classified according to the main geological controlling factors, type of gas accumulated, the relation between source and reservoir rocks, and number of gas-bearing formations in a verticle profile. A study of gas accumulation zone plays an important role in natural gas exploration because approximately 90% of gas fields is located on gas accumulation zone in a gas-bearing basin or gas-bearing region. Almost all the giant gas fields discovered are located on gas accumulation zones. Thus, a study of gas accumulation zone has not only theoretical significance but will increase the effeciency of gas exploration.
