The embodiment of the invention provides a method and device for fluid property identification. The fluid property identification method comprises: acquiring the volumes of reference gases in drilling fluid, with the volumes of reference gases being used for calculating the water index, oil index and gas index of a gas sample, which is all the gas separated from the drilling fluid; acquiring the water index, oil index and gas index of the gas sample according to the volumes of the reference gases and the volume of gas sample; identifying the fluid properties according to the water index, oil index and gas index, wherein the fluid properties are the fluid properties of the stratum where the gas sample is located. The embodiment of the invention realizes identification of a water layer, and improves the accuracy of fluid property identification. 本发明实施例提供种流体性质识别的方法及装置。本发明流体性质识别的方法，包括：获取钻井液中各参考气体的体积，所述各参考气体的体积用于计算气体样本的水指数、油指数和气指数，所述气体样本为从所述钻井液中分离出来的所有气体；根据所述各参考气体的体积和所述气体样本的体积，获取所述气体样本的所述水指数、所述油指数和所述气指数；根据所述水指数、所述
