| In recent decades,the rapid economic development in our country has accelerated the growth of energy demand.It will be very difficult to meet the needs of national economic development with conventional oil and gas supplies alone.Development and utilization of unconventional oil and gas industries has become an effective means to solve the problem of energy demand in our country.CBM industry in our country has had some development,but the overall development speed is slower,its development and utilization in our country still faces a series of difficulties and problems.In recent years,in the field of unconventional,low permeability reservoir fracturing micro-seismic fracture monitoring technology has become a more important new method,its main theoretical basis for the seismology,rock mechanics,geology and other disciplines.Micro-seismic monitoring technology can accurately describe the occurrence of fractures induced in the hydraulic fracturing process and the area affected by fractures.It has become one of the most popular geophysical fields at home and abroad.It is the most intuitive and most effective method in reservoir fracturing Timely,most informative monitoring tools.With the inversion of micro-seismic focal mechanism,deep calculation of source parameters and imaging technology,micro-seismic monitoring technology will continue to deepen its application scope,and its development prospect will be increasingly broad.Based on the basic principle of micro-seismic monitoring technology,the mechanism of micro-seismic generation and the process of micro-seismic monitoring,this paper focuses on the capture and localization of formation rupture signals in the development of CBM gas fracturing in CSN13V-06 well,Portray the role of the distribution of cracks and other functions,which guide the production unit well pattern deployment,improve oil recovery provides a basis for the application of micro-seismic monitoring technology in CBM exploration and development in China. |
