Adaptive wired communication method and well logging method and device

The invention provides an adaptive wired communication method and a well logging method and device. The adaptive wired communication method comprises the steps that: S1: a first terminal sends communication data and training data to a second terminal according to a communication parameter; S2: the second terminal evaluates the channel communication condition according to the training data, and adjusts the communication parameter adopted by the communication data according to an evaluation result; and S3: the second terminal sends the adjusted communication parameter to the first terminal to update the communication parameter. The adaptive wired communication method provided by the invention can be used for realizing an adaptive channel estimation function, thereby increasing the stability of a communication system.
