Micro-earthquake monitoring system and method

Abstract

The invention discloses a micro-earthquake monitoring system and method, comprising the following steps: collecting the micro-earthquake measurement data to be transmitted to an initial wave distinguishing unit, acquiring the waveform signal by the initial wave distinguishing unit in which the signal to noise ratio of the waveform signal is greater than the specified threshold, encapsulating and compressing the date of the waveform signal, transmitting the compressed data to the master station, acquiring the waveform signal via compressing and decoding the data, and processing the wave signal. The technical scheme of the invention not only reduces the micro-earthquake measurement data to be transmitted, improves the efficiency of transmission, reduces the collection cost, but also effectively restores the waveform data due to the data encapsulation and recombinant technology; at the same time, the whole beautifulness of the monitoring area is not destroyed, the installation is simple,the operation is simple and convenient, the network organization is flexible, the expansibility is good, the comprehensive cost is low; and the micro-earthquake monitoring system and method is particularly applicable to the field data collection.

Description

technical field [0001] The invention relates to the technical field of microseismic monitoring, in particular to a microseismic monitoring system and method. Background technique [0002] The passive microseismic underground fracture monitoring data acquisition, transmission and processing method can timely and accurately obtain the spatial and temporal parameters of microseismic events induced by oil field fracturing and water injection, so as to determine the distribution of underground fractures, which is suitable for oil and gas exploration and development. crack research. [0003] At present, microseismic monitoring adopts wired transmission mode. Although the dedicated line is dedicated, the signal transmission is relatively stable, and it is not easily disturbed by external factors, but the wired transmission mode will affect the appearance, the workload of wiring construction is heavy, the operation is complicated, and the maintenance is inconvenient. The advantages ...

[0003] At present, microseismic monitoring adopts wired transmission mode. Although the dedicated line is dedicated, the signal transmission is relatively stable, and it is not easily disturbed by external factors, but the wired transmission mode will affect the appearance, the workload of wiring construction is heavy, the operation is complicated, and the maintenance is inconvenient. The advantages of wireless transmission mode Because it will not destroy the overall beauty of the monitoring area, it is simple to install, easy to operate, flexible in networking, good in scalability, and low in overall cost. It is especially suitable for field data collection, but the transmission rate is low and the bandwidth is limited.
