Abstract: Zeolite minerals are developed in carboniferous,Permian and Triassic reservoirs in Karamay oil field.The zeolite minerals in the carboniferous vocanic rock(basalt)are different from those in the Permian and triassic clastic sedimentary reservoirs,both in types and origin.These minerals are significant to the study of the erosion of vocanic rocks and the diagenetic change of elastic sedimentary rocks.They affect pore structures in a complex manner.The existence of zeolite minerals is closely related to the migration and accumulation of hydrocarbons,both in vocanic and sedimentary reservoirs.The development of zeolite minerals should be considered in detail in reserve estimation and water flooding recovery.

摘要： 沸石类矿物在克拉玛依油田石炭系、二叠系及三叠系的储集层都有分布.在石炭系火山岩(玄武岩)储集层中的沸石类矿物,与在二叠系(及三叠系)粗碎屑沉积岩储集层中的沸石矿物,从沸石矿物的种类及成因上都是不同的.这些矿物对于研究火山岩的蚀变作用以及粗碎屑沉积岩的成岩演化有着重要的意义,并对储集层的储集空间和渗流条件形成一定的影响.无论对火山岩储集层还是对碎屑沉积岩储集层,沸石矿物的存在都与油气的运移和富集有较密切的关系,在储量计算、油藏注水开发中,沸石矿物也有重要影响.
