作者王华超(2019)在《库车拗陷北部构造带侏罗系阿合组储集空间分布规律及其控制因素》一文中研究指出:库车拗陷北部构造带下侏罗统阿合组储层是中国西部典型的深层致密砂岩储层。微孔隙、微裂缝在该致密砂岩储层内广泛发育并为该类储层典型的储集空间类型,对天然气的运移和聚集具有重要影响,同时也是引起储层应力敏感性、水敏感性和盐度敏感性的重要因素。但是微孔隙、微裂缝的规模分布及主控因素并未得到足够的关注。因此,对微孔隙、微裂缝规模分布及主控因素进行深入研究,将会对深层致密砂岩储层储集性能预测和敏感性的预测及预防具有重要意义。为揭示库车拗陷北部构造带下侏罗统致密砂岩储层微孔隙、微裂缝的成因类型、分布规律及主控因素,以岩矿数据分析为基础,以储层地质学、石油地质学以及沉积岩石学等多学科知识为理论指导,通过偏光显微镜、扫描电镜、X射线衍射、微米CT扫描、激光共聚焦显微观察等观测手段对北部构造带阿合组微孔隙、微裂缝分布特征及主控因素进行研究。微孔隙主要成因类型为泥质杂基微弱溶蚀微孔隙和少量粘土.矿物晶间孔,微孔隙的发育不受岩石颗粒粒度的影响,压实效应和溶蚀强度是导致微孔隙发育特征存在差异的主控因素,埋藏深度、构造应力和泥质含量是影响压实效应的主要因素。平面上,微孔隙的高值主要分布于溶蚀强度较大,压实效应较小吐孜井区和依南4井区,低值分布于溶蚀强度较小压实效应较大迪北102井区。垂向上,迪北段微孔隙的分布主要溶蚀强度和压实效应的影响,其高值主要分布于溶蚀强度中等,压实效应较弱的阿二段。吐格段微孔隙在垂向分布主要受溶蚀强度的制约,其高值主要分布在溶蚀强度相对较弱的阿一段和阿三段。微裂缝主要的成因类型为构造微裂缝、溶蚀微裂缝和收缩微裂缝。其中构造缝占微裂缝绝大部分,本次主要对构造微裂缝的分布特征及控制因素进行研究。整体上,构造微裂缝的发育受岩石颗粒粒度的影响,构造微裂缝发育程度与岩石颗粒粒度呈正比;平面上,构造微裂缝发育受构造变形强度、构造样式的控制。构造微裂缝在构造变形强度较大的克孜段、迪北段发育规模较大,在构造变形强度较弱的吐孜段和吐格段发育规模小,迪北段构造微裂缝发育程度受构造样式影响非均质性较强,在构造幅度较小的依南4、依南5井区发育规模较大,在构造幅度较大的依南2、迪北102井区发育规模较小;垂向上,构造微裂缝的发育主要受构造样式、泥质含量的影响:(1)在构造样式较平缓的依南4、依南5井区构造微裂缝在垂向上的发育主要受泥质含量影响,在泥质含量较低的阿二段发育程度高;(2)在构造幅度变化较大迪北102、依南2井区构造微裂缝发育主要受中和面效应的影响,位于背斜核部的依南2井区构造微裂缝含量随着埋深变大而降低,位于向斜核部的迪北102井区构造微裂缝含量随着埋深增大而增高。
