摘要

以岩心观察、钻井和成像测井等资料为基础,研究了准噶尔盆地红车断裂带石炭系火山岩储层裂缝特征。结果表明:石炭系火山岩储层裂缝非常发育,主要为构造运动作用形成的构造缝,大部分裂缝都被各种固体矿物不同程度地充填,影响了裂缝对油气储集和运移的有效性;裂缝方位主要为北北东向和北北西向,与主构造方向相同。根据上述基本特征和成因,对研究区裂缝进行了综合分类,探讨了裂缝与构造运动的关系,认为发育的4 期裂缝与构造运动期次相吻合,在纵向上裂缝主要分布于石炭系顶部向下250 m 的深度范围内,而在平面上主要集中在红车断裂带及次生断层附近。

Abstract

Based on core observation, well drilling and image logging data, the fracture characteristics of Carboniferous volcanic reservoirs in Hongche fault belt of Junggar Basin are studied. The result shows that fractures in volcanic reservoirs are well developed. They are mainly structural fractures formed in the tectonic movement, and most of themare filled with some kinds of solid minerals, which affects the effectiveness of the fractures to petroleum accumulation and migration. The main fracture directions are NNE and NNW, consistent with outstanding tectonic direction. According to the fracture characteristics and origin, the fractures are divided comprehensively. The relation between fracture and tectonic movement is discussed, and it is recognized that the four stages of fracturing are corresponding with the tectonic movement. Fractures mainly distributed at the depth of 250 meters under the top of Carboniferous in the vertical, and concentrated in Hongche fault belt and around secondary fault in the plane.
