| 摘 要： | 通过分析地震反射特征及AVO响应特征,结合监督模式识别、CM油气检测等地震属性,系统地对苏里格气田苏20区内主要目的层山1段气层特征进行综合研究。认为山1段气层在区内分布较为广泛,且主要受岩性控制,含气地层在地震剖面上主要表现为较强振幅中-低频反射与较弱振幅中-低频反射,AVO响应主要表现为近道强远道弱的特征。此外,除已知的中西部及东南部天然气富集区,研究区的北部及西南部地区均发育有一定规模的岩性气藏,为区内下一步的勘探重点。

| Abstract: | Based on the analysis of seismic reflections and AVO response,the authors systematically studied the gas reservoir characteristics of the 1st member of Shanxi Formation of Su20 block in Sulige gas field using the supervised SPR and CM hydrocarbon prediction. It is believed that the gas reservoirs of the 1st member of Shanxi Formation is widely distributed in the study area, and mainly controlled by lithology. On seismic reflection profiles, the gas reservoirs show high amplitude and middle-low frequency, or low amplitude and middle-low frequency. AVO response on near angle stack is stronger than that on the far angle stacks. In addition to the known gas-rich region in the middle-west and southeast of Su20 block, there exist some lithologic gas reservoirs in the north and southwest of the study area, which are the important targets of future exploration and development. |
