摘要: 长岭断陷深层输导体分为断层、砂层、裂缝和不整合面4种类型,断层是天然气垂向穿层运移输导的主要通道,与烃源岩互层的砂层可作为天然气侧向输导通道,裂缝为火山岩储层天然气输导提供良好通道,是火山岩层能作为有效储层的关键。长岭断陷深层输导体系的有效性受烃源灶位置与生排烃期、天然气运移路径与输导体匹配等因素影响,在烃源岩生排烃期及优势运移路径上呈连通状态的输导体系对天然气聚集至关重要。天然气平面分布的广泛性和垂向上的多层系与输导体系的时空配置关系密切,近烃源断裂输导是长岭深层火山岩气藏最主要的输导方式,控制了深层天然气的运聚规律,天然气沿断裂运移输导并在其附近聚集分布。Abstract: There are four deep transportation types in the Changling Fault Depression: fault,sandstone,fracture and unconformity surface.Faults are the main pathways for gas vertical migration.Sandstones which interbed with source rocks are the main pathways for gas lateral migration.Fractures in volcanic rocks provide favorable pathways for gas migration,which is the controlling factor for the effectiveness of volcanic reservoirs.The effectiveness of deep transportation system in the Changling Fault Depression is affected by the matching of hydrocarbon kitchen location and hydrocarbon generation and expulsion stages as well as the matching of gas migration pathway and transportation system.The transportation system which exists during hydrocarbon generation and expulsion stages and is connected along favorable migration pathways is critical for gas accumulation.Closely related to the time and space distributions of transportation system,natural gas is widespread laterally and is found in multiple layers vertically.Fault transportation close to source rocks is the most common transportation way for volcanic reservoirs in the Changling Fault Depression,which controlls the regular migration pattern of deep gas.Gas migrates along faults and accumulates nearby.
