The invention provides a comprehensive recognition system for loss of drilling fluid. The comprehensive recognition system for loss of drilling fluid is composed of a cable, a cable joint, a measurement and control electronic short joint, a temperature pressure noise short joint, an apparatus protection head, a data processor and a flow sensor. The data processor is connected with the cable. The cable is connected with the cable joint connected with the measurement and control electronic short joint. The measurement and control electronic short joint is connected with the temperature pressure noise short joint. The temperature pressure noise short joint is connected with the apparatus protection head. The flow sensor is connected with the data processor. The temperature pressure noise short joint is composed of a temperature sensor, a pressure sensor and noise receiving transducers, all of which are arranged on a short joint framework. The comprehensive recognition system for loss of drilling fluid has following beneficial effects: by utilizing three modes such as temperature, pressure and noises, the system is used for measuring loss positions of the drilling fluid and also measuring indicators such as loss pressure and circulation emissions; data is comprehensively processed by software in order to obtain parameters such as loss types, characteristics and leakage zones; accuracy of loss determination is improved; and key data is provided for the next step of leaking stoppage such that the comprehensive recognition system does with its purpose.
