摘　　要：南翼山油田水室内蒸发过程中,在类光卤石复盐结晶段析出一种长针状"镂空"形貌的晶体。通过XRD、SEM、EDS等仪器分析,并结合化学分析方法对该晶体进行了分析和表征,确认其是组成为K(NH4)Mg2Cl6.12H2O的铵钾光卤石复盐。Needle-like crystals with a hollowed-out morphology were precipitated from the oilfield water during its evaporation at the carnallite-precipitation step.The crystals were identified as a sort of carnallite-type double salt K（NH4）Mg2Cl6·12H2O with the help of XRD,SEM,EDS and chemical analysis.
