The invention discloses a test method for a hydrate rock core sample. The test method relates to the technical field of hydrate research, and adopts a hydrate rock core sample preparation module and arock core parameter test module, wherein the hydrate rock core sample preparation module is used for preparing the hydrate rock core sample in a hydrate rock core former; the rock core parameter testmodule comprises a mounting plate, a temperature adjusting jacket arranged on the mounting plate, and a probe slidably arranged on the mounting plate; the hydrate rock core former is placed inside the temperature adjusting jacket; and the probe is used for measuring the hydrate rock core sample in the hydrate rock core former. The test method has the beneficial effects that a special test systemcan rapidly carry out the joint detection of acoustic and electrical features under conditions of normal pressure; the acoustic and electrical parameters of a natural gas hydrate rock core sample canbe tested simultaneously, and the acoustic and electrical feature data of different types of natural gas hydrate rock core samples can be obtained, thereby providing an effective detection basis and atheoretical basis for exploring an actual natural gas hydrate.
