Summary:The invention provides an intelligent drill stem compensation type electric contact, which is used for the intelligent well and can realize the wired real-time two-way closed loop high-rate information data transmission channel and can supply power to the well. The intelligent drill stem compensation type electric contact mainly consists of a male electric contact and a female electric contact. The electric current or the signal is transmitted from the upstream line to the conductance loop of the male electric contact and then to the conductance loop of the female electric contact through the close contact of the conductance loops between the female and male electric contacts, then the current is transmitted to the line connected with the conductance loop, and finally the power and the signal are transmitted to the bottom of the well through circulation in turn; in like manner, the return circuit of the current or the signal is realized through another pair of conductance loops of the female electric contact
