|
摘要
本文以松辽盆地长岭断陷达尔罕断凸带火成岩气藏预测为例,从已钻遏火成岩的钻井资料出发,结合钻井地质信息与地震资料,利用地震特殊处理技术识别火成岩.通过分析结果,研究该区的火成岩分布特征及油气成藏规律,建立判断火成岩的地球物理模式.结合本区域地质资料,预测了本区的火成岩分布,总结出适合本区火成岩构造特征的火成岩气藏识别技术,包括火成岩测井识别技术、火成岩地震剖面反射特征识别技术、火成岩地震相识别技术和地震反演技术等来预测火成岩的空间展布规律,了解火成岩与构造的关系.进而识别火成岩圈闭,总结断陷层系油气成藏组合,为在本区寻找火成岩气藏提供系统分析方法.
Forecasting volcanic reservoirs within Darhan zone of bruchfahen in Changling Fault-depression of Liaohe Basin was given in this paper as an exmple to identify volcanic rocks by special techneque of processing seismic data, based on welling data of volcanic rocks and combined with geological information from welling and seismic data. Basically, we studied distributions of volcanic rocks in this area and reservoirs character of oil and gas, and built geopbycial model for distinguishing volcanic rocks. Together with regional geological data, we forecast the distribution of volcanic rock in this area, and summarized the technique of identifying volcanic rocks. The technique of distinguishing volcanic rocks consisted of well-data identifying, recognising reflective character and seismic phase of volcanic rocks in seismic profile, and seismic inversion, to synthetically predict spatial distribution of lava, the relationship between lava and teconics. Further, we identified the closure of volcanic rocks, summarized assembled charater of oil and gas in fah-depression layers. This study provided a new approach to search for volcanic reservoirs in this area.
