Advances and Combined Applications in Hydraulic Fracturing Monitoring and Diagnostic Technology
The monitoring and diagnosis technique for hydraulic fracturing has become an important supporting technology for unconventional reservoir development.In order to improve the application effect,we analyze the application situation of micro-seismic monitoring,distributed fiber optic sensing,electromagnetic monitoring,pressure testing,tracer production profile testing,downhole video imaging,array acoustic imaging logging and other technologies in hydraulic fracturing monitoring at home and abroad.Based on the basic principles and construction technology of different monitoring and diagnosis technologies,the technologies are classified according to different standards,and the applicability,technical advantages and limitations of various monitoring and diagnosis methods are systematically summarized and analyzed.Based on engineering practice cases,the idea of joint application of fracturing monitoring and diagnosis technologies is put forward.The research results show that the technical advantages of different fracturing monitoring and diagnosis methods are significantly different,and they need to be scientifically and rationally selected according to the monitoring timing,objectives,and processes.The combination of fracturing monitoring and diagnosis technologies can overcome the limitations of individual methods,and realize the accurate characterization of fracture network extension and the analysisof the post-fracturing production patterns.This method provides valuable insights into the application of fracturing monitoring and diagnosis technologies in unconventional resource development.
