摘要： 乌夏地区二叠系火山岩储集层储集空间中裂缝发育,是油气渗流的重要通道,其构成了油气储集的重要空间,控制了储集层分布。针对该区火山岩储集层分布和结构构造特点,研究和分析了火山岩的裂缝特征,利用岩心观测和成像测井等方法对火山岩储集层的构造裂缝进行了识别,结果表明,这些方法能更准确地进行了裂缝参数的判定与裂缝孔隙度的计算及火山岩储集层评价。

Abstract: There are developed fractures or fissures in the Permian volcanic reservoirs in Wu-Xia area, which control the reservoirs' distribution as important channels for hydrocarbon flowing and storage. In view of the volcanic reservoir distribution and structural feature, this paper presents the research and analysis of the fracture characteristic of the volcanic rocks and the identification of structural fracture by means of rock observation and image logging. The results show that this method can be used to precisely determine the fracture parameters, calculate fracture porosity and evaluate the volcanic reservoir.

Key words: Junggar basin, Wuerhe-Xiazijie (Wu-Xia) area, Permian, volcanic rock, fracture, porosity
