This book introduces the downhole engineering cybernetics a new subdiscipline focusing on the downhole control engineering of oil and gas wells by using the principles and methods of engineering cybernetics. It covers four main parts:

theoretical basis downhole system dynamics, control signal analysis;

technological basis design of downhole control mechanism, downhole parameter acquisition, and transmission technology;

laboratory construction and experimental methods;

product development downhole control systems and tools. This book is a valuable reference both for researchers and engineers in the relevant fields.
