摘要
近年来,随着石油工业的发展和勘探技术的提高,火山岩油气藏相继在国内外都有比较多的发现。由于火成岩油气藏具有分布广但规模较小、初始产量高且递减快、储集类型和成藏条件复杂等特点。目前,对该类油气藏的系统研究方法相对缺乏,勘探开发技术尚不够完善。在此总结了火山岩储集层的特征及油藏类型,阐述了火山岩油气藏的开发方式,分析了国内外火山岩油气藏研究及勘探开发的成功实例,提出了火山岩油藏开发的几点建议,以期对吐哈探区三塘湖盆地火山岩油气藏的勘探开发起到一定的借鉴作用。
In recent years, as the development of petroleum industry and the advance of exploration technology, many volcanic reservoirs have been discovered at home and abroad. Volcanic reservoirs are characteristic of the wide distribution, but the small scale, high initial oil production but rapid decline, and with complex reservoir types and accumulation conditions. The systematic research method for this type of reservoir is relatively absence, exploration and development technology is not perfect. In this paper, reservoir characteristics and reservoir types of volcanic rock are summarized. Development mode of volcanic reservoir is present. Successful examples of volcanic reservoir research and exploration and development at home and abroad are analyzed. Advice on development research for volcanic reservoir is recommended. All of these are expected to play an important reference role in exploration and development of volcanic reservoir in Santaughu basin of Tuba oil field.
