This book is divided into four chapters. The first chapter introduces the basic knowledge of foam flooding technology, including foam flooding principle, classification and properties of foam stabilizers, foam generation device and its process parameters, and laboratory evaluation methods of foam flooding. The second chapter describes the application of solar energy in foam oil displacement, including the introduction of solar energy, the mechanism of photothermal conversion, the application of solar energy in foam oil displacement and laboratory evaluation methods. Then, the third chapter discusses the coupling study of foam oil displacement and solar energy, involving the correlation study of foam performance and solar energy input, the correlation study of foam oil displacement system and solar energy input, and the correlation study of foam oil displacement effect and solar energy input. Finally, the fourth chapter introduces the numerical simulation research of foam oil displacement and solar energy coupling, including the numerical simulation method and principle, the establishment of numerical simulation model, the numerical simulation of foam oil displacement system and solar energy input, and the numerical simulation of foam oil displacement effect and solar energy input. 

Through in-depth research on the technical basis of foam oil displacement, the application of solar energy in foam oil displacement, the study on the coupling of foam oil displacement and solar energy and numerical simulation, the purpose is to reveal the correlation between the performance of foam oil displacement system and solar energy. It is hoped that through the elaboration of this book, readers can better understand the correlation between the performance of foam oil displacement system and solar energy, provide new ideas and methods for oilfield development and energy utilization, promote the development of foam oil displacement technology and promote the application of solar energy in oilfield development, which has important theoretical and application value.
