西湖凹陷渐新统花港组储层砂岩成岩环境演化探讨
Keywords: 西湖凹陷,花港组,成岩环境,有机酸
Abstract:
？通过大量的岩石薄片显微观察，结合其他成岩阶段划分的标志，认为研究区花港组成岩阶段主要处在晚成岩阶段b期;采用光学显微镜、扫描电镜等观察分析东海陆架盆地西湖凹陷花港组储层砂岩自生矿物种类、组合及岩石结构、孔隙类型和结构特征，识别出酸性成岩环境和碱性成岩环境2种类型。酸性成岩环境以长石溶蚀+次生溶孔+自生高岭石+石英次生加大为特征；碱性成岩环境则以石英溶蚀+晚期亚铁碳酸盐充填、交代为特征。酸性和碱性成岩环境演化机理主要受控于烃源岩中干酪根核外围含氧羧基和酚基通过热裂解产生一元和二元水溶性羧酸以及酚类。在中成岩阶段a期，当ro值在0.5％～1.3％之间变化时，有机质通过脱羧基作用生成一元、二元有机酸，并释放出co2,导致孔隙流体性质为酸性；当烃源岩中有机质演化程度升高,有机酸遭到破坏，脱羧基作用减弱，co2来源减少,孔隙流体性质逐渐由酸性向碱性演变。
