Mantle fluid is one of the frontier fields in earth science research today, which has important research value. The paper summarizes the means of mantle fluid composition research, the experimental methods and the progress in recent years. The existing problems are discussed. The areas that need further work are as follows: (1) To determine the suitable experimental methods for the determination of mantle fluid composition in order to carry out Global comparison of data; (2) carrying out comparative studies of isotopic systems of mantle plumes with PbSrNdHfOs isotopes in different types of mantle source areas; (3) studying mantle fluids in different tectonic units and establishing mantle source zones (4) to study the mantle fluid during the crust-mantle interaction and to identify the distinguishing marks of the recirculated crustal components in the mantle fluid; (5) To investigate the geomagnetic characteristics of the mantle fluid during the geological history (6) To carry out research on mantle-derived H2 and hydrocarbons to provide basis for non-biogenic gas theory and exploration.
