    摘要： A forced cooling circulation system for drilling mud, which includes a refrigeration unit (1), a secondary refrigerant tank (4), a coaxial convection heat exchanger (12) for mud and a mud pond (17), is disclosed. The refrigeration unit (1) is in connection with the secondary refrigerant tank (4) and the coaxial convection heat exchanger (12) for mud via a pump (2), and the coaxial convection heat exchanger (12) for mud is in connection with the mud pond (17) via a pump (15) and pipelines. Heat exchange tubes of the coaxial convection heat exchanger (12) for mud are disposed as a double-layer structure or a multi-layer structure, and the inner heat exchange tubes (23) are mounted inside of the outer heat exchange tubes (25). The secondary refrigerant or the mud is circulated in the annular space between the inner heat exchange tubes (23) and the outer heat exchange tubes (25), and the mud or the secondary refrigerant is circulated in the inner tubes (23). The flow of the circulated mud is opposite to that of the circulated secondary refrigerant, and insulation material (24) is painted on the external wall of the outer tubes (25).
