摘要
火成岩油气藏作为油气勘探的一个新领域,已引起石油界学者的高度重视。准噶尔盆地车排子地区石炭系广泛分布巨厚火山岩,并已有油气的发现。在火山岩岩性识别的基础上,对火山岩石的孔隙类型、孔缝结构、物性和含油性进行分析,认为该地区石炭系火山岩发育玄武岩、安山岩、玄武安山岩、流纹岩、玄武质角砾岩、安山质角砾岩、凝灰岩,其中火山角砾岩和玄武岩在该地区分布最广,储集层主要分布在这2类岩石中,储集空间包括原生孔隙和次生孔缝,储集性能中等,主要属于Ⅱ类和Ⅲ类储集层。
As a new field of oil and gas exploration, igneous reservoirs have greatly attracted the attention of the scholars in petroleum world. The thick volcanics are widely distributed in Carboniferous formation of Chepaizi Region in Junggar Basin and the petroleum has been discovered in the region. Based on the lithologic identification of volcanic rock, it is believed that the basalt, andesite, basaltic andesite, rhyolite, basaltic breccia, andesitic breccia and tuff were developed in Carboniferous volcanic rock of the region through the analysis of pore type, pore configuration, reservoir physical property and oil-bearing property for volcanic rocks. The most widely distributed rocks were lava breccia and basalt in the region and the reservoirs were mainly distributed in these two types of rock. The reservoir spaces included the primary pores and secondary pores, with moderate reservoir capability. The reservoirs mainly belong to type Ⅱ and type Ⅲ ones.
