There are many kinds of microseismic fracture monitoring(MFM)methods, MFM results also have their own characteristics, but they cannot accurately and completely reflectthe height, length, width and the spatial distribution of fractures. The MFM source locations are significantly important in oil and gas well layouts, and the optimized fracturing construction increases oil and gas production. The current popular MFM methods are mainly ground monitoring and well monitoring, respectively. The ground monitoring method has a higher resolution in the horizontal distribution of fractures than in the vertical direction. The well monitoring method has a good effect on the vertical direction of the fractures, but it cannot clearly reflect the process of fractures in the horizontal direction. Therefore, a combination of two methods well combined with ground MFM method (Fig. 1) will be able to clearly monitor the length, height, width and development of fractures.
