我国实施以煤炭资源为主,油气资源、新能源协同发展的能源战略,对煤炭资源的需求量逐渐扩大,地震勘探作为煤炭等资源勘探的重要手段,是一个巨大的系统工程。地震信号的获得就成为了重中之重,要从复杂多样的噪声与干扰中检测到极为弱小的地震信号来探查地下的煤炭资源、油气资源,就要求用于地震勘探的地震仪器必须能够全面高保真地记录地震信号,反映到地震仪层面即为系统的性能指标。
China’s implementation of the energy strategy with coordinated development of coal resources, oil and gas resources and new energy sources has gradually expanded the demand for coal resources. As an important means of exploration for resources such as coal, seismic exploration is a tremendous systematic project. The acquisition of seismic signals becomes the most important task. To detect extremely weak seismic signals from complex and diverse noises and disturbances to explore underground coal resources and oil and gas resources requires that the seismic instruments used for seismic exploration must be comprehensive High-fidelity record of seismic signals reflected in the seismograph level is the system performance index.
