摘要
火山岩油气藏作为一种特殊的油气藏,近年来愈来愈受到人们的关注,但是在开发上还有不少难点,如初始产量高且递减快,火山岩自身组成成分、构造、结构也比较复杂,储层裂缝分布规律的识别比较困难。目前,对该类油气藏的系统研究方法相对匮乏,勘探开发技术尚不完善。通过对不同的岩性识别方法、储层裂缝的认识及相关的火山岩开发技术的讨论,结合国内外火山岩油气藏研究及开发的例子,提出对火山岩油气藏开发的相关建议,以期对火山岩油藏开发起到一定的指导作用。
As a special kind of oil and gas reservoir, volcanic rock oil and gas reservoirs are widely distributed but small in scale, with high initial production and rapid decline. The composition and structure of volcanic rock itself are also complicated, and it is difficult to identify the distribution law of reservoir fractures. At present, systematic research methods for this type of oil and gas reservoirs are relatively scarce, and exploration and development technologies are not yet perfect. Based on the understanding of different lithology identification methods, reservoir fractures, and related volcanic rock development technologies, combining domestic and foreign research and development examples of volcanic rock oil and gas reservoirs, relevant suggestions for the development of volcanic rock oil and gas reservoirs were put forward, which could play a certain guiding role in the development of volcanic reservoirs.
