世界火成岩气藏勘探开发现状与展望

Current Situation and Prospect on E & P of Global Igneous Rock Gas Reservoirs

全球火成岩气藏主要分布在美国、日本和澳大利亚等地区。火成岩气藏的勘探以地震技术为基础结合非地震勘探技术,其开发技术大体与常规气藏开发相似。未来的勘探开发应对有效储层识别和地震预测、储层连通性及开发方式优化、二氧化碳防腐等方面进行进一步的研究和攻关。建议加强其地质理论方面的研究,通过引进—消化—改造的模式不断发展和提高其物探技术,重点发展非地震勘探技术。

Globally, igneous rock gas reservoirs are mainly distributed in some countries of USA, Japan and Australia. Their exploration technologies include mainly seismic ones and partly non-seismic ones whereas their production technologies are roughly similar with ones used in conventional gas reservoirs. A future E & P to igneous rock should focus on some aspects such as to identify and predict seismically the effective reservoir, to study the reservoir connectivity, development-pattern optimization and CO2 preservation. In China, an E & P to igneous rock gas reservoirs should concentrate more on studying the geological theory, developing and improving continuously the geophysical technologies with non-seismic ones as the soul.
