Development of new lost circulation materials (LCM) of high efficiency is the key in controlling and preventing lost circulation. Based on the advanced idea and methods of intelligent material science, the type, characteristics and working mechanisms of shape memory intelligent LCM are discussed and analyzed. Status quo of studying on the intelligent LCM with temperature sensitive shape memory both in China and abroad is introduced. This paper also discusses the self-adaptive fracture sizes which the intelligent LCM with temperature sensitive shape memory LCM can be used, and the lost circulation control property and working mechanism of temperature sensitive intelligent LCM with high pressure bearing capacity. Suggestion and outlook are presented to the preparation, evaluation methods and field application techniques of temperature sensitive shape memory LCM which may lead to the innovation of lost circulation control and prevention technologies.
