Abstract

The invention provides a microseismic monitoring analog system which belongs to the field of micro-vibration generation and monitoring. The microseismic monitoring analog system comprises a simulation experiment fracturing device, a microseismic signal detection device and a microseismic simulation acquisition device. The simulation experiment fracturing device is used for generating fracturing fractures and sending out a microseismic signal. The microseismic signal detection device is used for detecting the microseismic signal and converting the microseismic signal to an analog electrical signal. The microseismic simulation acquisition device is sued for controlling the simulation experiment fracturing device and processing the analog electrical signal generated by the microseismic signal detection device. According to the invention, the problem that a general microseismic simulation monitoring system has poor simulation accuracy and poor precision is solved, the field well fracturing three-dimensional microseismic monitoring process can be simulated realistically, and the system has certain instructive effect on actual microseismic exploration.

Description

technical field

[0001] The invention belongs to the field of micro-vibration generation and monitoring, and specifically relates to a micro-seismic monitoring simulation system, which can use micro-fracturing to generate and detect micro-seismic signals under indoor conditions, and is used to simulate micro-seismic signals generated by water fracturing in oil and gas wells And the detection process of microseismic signals. Background technique

[0002] At present, most large oil and gas fields in my country have entered the late stage of exploitation, and the oil and gas resources in low permeability oil and gas fields are expected to become the driving force of future energy and economic development, and the oil and gas in these tight reservoirs need to be fracturing to achieve economical extraction. Fracturing is to use pressure to open one or several horizontal or vertical fractures in the formation, and use proppant to support the fractures, reduce the flow resistance of...
