A multifunctional testing platform and testing method for a microseismic system

Abstract

The invention discloses a multifunctional testing platform for a microseismic system, which includes a microseismic signal collection and transmitting device, and further includes first to fourth microseismic monitoring wells arranged uniformly and clockwise on the outer circle sequentially, and sequentially arranged evenly and clockwise on the inner circle. For the fifth to eighth microseismic monitoring wells, the outer circle and the inner circle have the same center, and a microseismic signal transmission well is set at the center of the circle. The first microseismic monitoring well is located in the east of the microseismic signal transmission well, and the fifth microseismic monitoring well is located In the southeast of the vibration signal transmission shaft, the microseismic monitoring sensors installed in the first to eighth microseismic monitoring wells are respectively connected to the microseismic signal acquisition and transmission devices. The invention also discloses a method for testing the positioning accuracy of the microseismic source, which can use the positioning algorithm to be tested to locate the position of the vibration source according to the monitored microseismic signal, and compare it with the position of the real vibration source to determine the positioning accuracy of the microseismic source. Position the pros and cons of the algorithm and end the test.
