The invention discloses an oil mud two-stage thermal desorption system with a high water content and integrated skid-mounted equipment, and belongs to the technical field of oil mud treatment devices.The system includes a feeding system, a first-stage thermal desorption system, a second-stage thermal desorption system, a discharge system, a steam condensation and oil-water separation system and anitrogen protection system, which are integrated in the integrated skid-mounted equipment. The system aims at deficiencies of high energy consumption and limited treatment capacity in the oil mud thermal desorption method treatment process, reduces the water content of the oil mud through microwave thermal desorption pretreatment of first-stage thermal radiation, uses the indirect thermal desorption of second-stage heat conduction to separate oil from the soil, and improves the thermal efficiency and the processing capacity of the equipment by a first-stage thermal desorption distributor, a second-stage thermal desorp
