Wireless network-based micro-seismic fracturing real-time monitoring system and monitoring method

Abstract

The present invention relates to a wireless network-based micro-seismic fracturing real-time monitoring system and monitoring method. The system is mainly composed of a server, wireless micro-seismic data acquisition stations, a field hand-held inspection terminal and a wireless AP. In the system, interconnection is realized by WIFI, and the UDP and FTP are adopted to perform communication; according to the acquisition station, an STM32F207 processor is adopted as a main control unit, a 32-bit ADS1282 is adopted as a data acquisition unit, and therefore, data acquisition accuracy can be improved, and the power consumption and cost of the acquisition station can be decreased; a network structure is in a master-slave AP topological structure and forms a complete fracturing monitoring system together with the server and the acquisition stations, and therefore, the problems of short wireless transmission distance and slow download speed can be effectively solved; and the hand-held device and the acquisition stations perform data exchange through using low-power Bluetooth communication, so that data transmission of a data flow form can be realized. The system integrates the advantages of each part, can ensure strict data synchronization acquisition and real-time and reliable fracturing state monitoring and has a high engineering application value.

Description

Technical field [0001] The invention belongs to the technical field of microseismic fracturing monitoring in geophysical prospecting, and particularly relates to a wireless network-based real-time monitoring system and monitoring method for microseismic fracturing. Background technique [0002] Microseismic fracturing monitoring technology is an important new technology in the field of fracturing reformation of low-permeability oil and gas reservoirs in recent years. This technology detects the microseismic waves induced by the fractured well during the fracturing process by arranging geophones on the ground within a few kilometers of the wellhead, and uses it to describe the geometric shape and spatial distribution of fracture growth during the fracturing process. It can provide the height, length and azimuth angle of the fractures generated by fracturing construction in real time. Using this information can optimize the fracturing design, optimize the well pattern or other oilf...
