The present invention relates to a static cone penetration combined type geochemical microelectrode probe system, comprising a base and a static cone penetration test probe and at least one microelectrode that are disposed on the base; the static cone penetration test probe is disposed in the center of the base; at least one microelectrode is arranged around the static cone penetration test probe; and the conical tip of the static cone penetration test probe is 4-8cm greater than the conical tip length of the microelectrode. The static cone penetration test probe and the microelectrode are combined, and the threshold value of the static cone penetration test probe is set according to the limiting breaking strength of the microelectrode, thereby ensuring that the microelectrode stops penetrating the deposits before reaching the limiting breaking strength, and protecting the microelectrode from being damaged. At the same time, the microelectrode is driven to go deeper. The microelectrode probe system can be app
