The approach to the formation of sand samples containing methane hydrate of a non-cementing type is studied. The approach is to inject methane-rich water in the sample after formation of methane hydrate by the "excess gas" method. Laboratory research is carried out on a specialized setup that allows to form hydrate -bearing samples and to study their acoustic properties during the experiments. The results are compared with the data of previous experiments on sand samples containing tetrahydrofuran (THF) and methane hydrate formed by the "excess gas" method. It is shown that the studied approach allow to form samples containing methane hydrate of a non-cementing type.
