Abstract: The development of coalbed methane (CBM) resources by injection thermal fluids is a development method proposed in recent years. Laboratory research and field preliminary practice have proved that the technology has broad application prospects. In this paper, a superheated steam pipe flow model is established on the basis of the characteristics of superheated steam pipe flow and the features of CBM reservoirs. The Effects of strong heat loss and strong friction loss on superheated steam status are studied, and the Joule-Thompson effect on temperature and pressure is revealed. The main findings are: (a) The status of superheated steam are relatively independent. However, the status of superheated steam are influenced by Joule-Thompson effect; (b) The injection speed has a critical value. When injection speed is lower than critical value, fluid temperature increases rapidly with injection speed; when injection speed is lower than critical value, fluid temperature decreases with injection speed. The critical value in this paper is 1.6 kg/s; (c) The critical value of the injection rate is only valid for temperature; (d) When heat loss as well as frictional force loss are large, Joule-Thompson effect becomes weak and negligible.
