摘　　要：分析了天然沸石做为油井水泥外掺料的晶体结构方面的依据，回顾沸石水泥水化的机理，根据Ｘ－射线衍射、扫描电镜、能谱分析的结果说明了沸石油井水泥的水化作用特征，证明了沸石与油井水泥发生化学反应并生成了凝胶状物质，指明了不同沸石含量的沸石油井水泥微观结构。Abstract The conclusion of using zeolite as oilwell cement additive material is proved withthe crystalline struIcture of zeolite cluster mineral.The mechanism of hydration for zeo-lite cement is reviewed.The features of hydration action for zeolite oil well cenment areanalyzed by means of X-ray difraction, scan eletroic microscope. energy spectrum da-ta. The zeolite oil well cemet rock microscopic structure figures are given in differentzeolite content range. The result that combining materials of and oil well cementhydrate is the new gelled matter is formed.SUBJECT TERM:zeolite. oil gas well, cementing X-ray diffraction. scan electronic microscope,energy spectrum
