Distribution design method of ground microseism monitoring station

The invention relates to a distribution design method of a ground microseism monitoring station, mainly solving the problem in an existing ground microseism monitoring technology that a distribution design of the station is lack of evidences. The distribution design method comprises the following steps: establishing a three-dimensional fine geologic model according to existing three-dimensional seismic data and well drilling data of working areas; counting up microseism signals monitored in a former well of the area to obtain a theoretical microseism signal waveform; calculating distribution of energy transmitted to the ground surface by theoretical microseism signals by forward modeling through a three-dimensional wave equation; and taking energy distribution as the evidence and combining actual ground conditions to design station distribution ranges and positions so that the stations can be distributed at the parts with relatively great energy values as much as possible. With the adoption of the technology, the blindness of the distribution design of the stations in ground microseism monitoring is reduced, the capability of monitoring the microseism signals on the ground is enhanced, and the distribution design method can be used for industrial production of the microseism monitoring of hydraulic fracturing grounds.
