摘　　要：分析了靖安油田上三叠系延长统浊沸石的形成条件及形成机理。阐述了浊沸石的成岩作用特征 ,及其对储层的影响。指出浊沸石溶蚀能极大地改善储层低孔隙度、低渗透率的特征 ,是最有利的含油储层分布区。Formation factors and mechanism of the laumontite in upper Triassic Yanchang group of Jingan oilfield are analyzed. The features of diagenesis and its effect on reservoirs are introduced. It is pointed out that the dissolution of laumontite may greatly improve lower porosity and permeability of the reservoirs, which is the most favorable distribution area of oilbearing reservoirs.
