通过总结近年来油气勘探成果,认为珠江口盆地番禺—流花地区具有良好的天然气成藏条件,气源充足,储盖优良,圈闭条件优越,复合输导体系使油气运移顺畅无阻,是天然气勘探的重点区域。进而总结研究区天然气成藏特征,即表现为晚期—超晚期成藏,气藏类型单一,其在纵向上主要集中分布在珠江组下段,在平面上呈NE向条带状分布,明显受油气主运移方向的控制。通过天然气成藏条件与天然气分布关系研究,认为研究区天然气分布主要受构造脊、圈闭与储盖的匹配、封盖及保存条件等共同控制。
By summarizing the results of oil and gas exploration in recent years, it is considered that the Panyu - Liuhua area in the Pearl River Mouth Basin has good natural gas accumulation conditions, abundant gas source, excellent reservoir cover and superior trapping conditions. The composite transport system makes the migration of oil and gas smooth and natural. Key areas for exploration. Furthermore, the accumulation characteristics of natural gas in the study area are summarized, that is, the late-super-stage hydrocarbon accumulation is characterized by a single type of gas pool, which mainly distributes longitudinally in the lower segment of the Zhujiang Formation and distributes in a NE- Control of the main transport direction. Based on the research on the relationship between natural gas accumulation conditions and gas accumulation conditions, it is considered that the distribution of natural gas in the study area is mainly controlled by the matching of structural ridges, traps and reservoirs, capping and preservation conditions.
