火山岩油气藏已经成为油气勘探的重要靶区,但火山岩储层的发育特点和成藏理论并不完善,针对火山岩储层的勘探尚未形成一套完善的预测思路.通过对国内外火山岩油气藏的特征分析,总结了原生孔隙型、风化壳型和构造裂缝型3种典型火山岩油气藏的成藏特点,结合这3种油气藏的特点和准噶尔盆地4个工区的勘探实践,提出了一套综合预测思路,主要包括岩性岩相预测、物性预测和流体预测3个方面.

Volcanic rock reservoirs have become an important domain for oil and gas exploration; however, their development characters and accumulation theories are still far from perfect, and a mature exploration idea for vol-canic reservoirs is demanded. The characters of volcanic reservoir at home and abroad are analyzed and the reser-voir formation characters of three typical kinds of volcanic rock reservoir including primary pore reservoir, weath-ered crust reservoir and structural-fractured reservoir are summarized in this article. Combined with the explora-tion applications of four volcanic reservoir areas in the Junggar Basin and the characters of three typical reser-voirs,a comprehensive exploration idea is proposed, which contains facies and lithologic prediction, physical pa-rameter prediction and hydrocarbon detecting.
