    Abstract：Operating temperature of low temperature drilling rig in Russian polar is -45℃ to +45℃. Effective insulation measures must be taken for associated equipment of drilling rig in order to ensure normal drilling operation in low temperature conditions and thus increase drilling efficiency. Drilling rig manifold is one of key equipment， which is the main pipeline supplying the drilling fluid. The ambient temperature will directly affect drilling operation. In low temperature conditions， drilling fluid manifold must be kept within certain temperature range and normal drilling works can be ensured. Based on characteristics of low temperature drilling pipe manifold， introduced are characteristics and application of electrical heat tracing technology， calculated is heat loss and need of drilling manifold in low temperature conditions. Designed is one set of electrical heat tracing system suitable for low temperature drilling rig manifold， which can ensure that drilling system operates properly in low temperature conditions， and further more， the system has energy-saving and environment-friendly features.
