摘要: 辽河东部凹陷火山岩油藏为裂缝-孔隙型双重介质油藏,为此根据测井、地震等资料,运用岩心描述与薄片分析、铸体、压汞及物性测定等多种分析测试手段,系统研究了本区火山岩的分布、岩石类型、储集空间特点及油气成藏特征,深入研究了这种特殊岩性油藏的开发特征及产生这些特征的原因,提出相应有效的解决方案.应用水平井技术对火山岩油藏进行高效开发实践,具体分析了水平井技术在火山岩油藏开发中可以发挥的技术优势及局限性,认为在适合的条件下水平井技术是火山岩油藏高效开发的重要手段.

Abstract: The volcanic reservoirs in Eastern Liaohe Depression belong to the fracture-pore dual media type. This paper systematically studies the distribution, rock types, reservoir space and hydrocarbon accumulation characteristics of volcanic rocks in this area based on well logging and seismic data by using multiple analysis and testing methods such as core description and thin section analysis, cast, mercury penetration and physical property measurement. Based on the studies of the development characteristics of such special lithology reservoirs and the reasons for these characteristics; corresponding solutions are propose. Horizontal well technology has been applied to efficient development of volcanic reservoirs. The technical advantages and limitations of horizontal well technology for developing volcanic reservoirs are also analyzed. It is concluded that under proper conditions, horizontal well technology is an effective way of developing volcanic reservoirs.
