Development and application of a high-fidelity and high-resolution telemetry seismic data acquisition system

Seismic exploration is characterized by complex geological conditions, large exploration depth and high-resolution requirement. Conventional seismic exploration techniques and equipment used in oil and gas exploration are difficult to meet the needs of metallic ore exploration. To solve this problem, a portable distributed telemetry seismic exploration system (named SE863) is developed. A series of key technologies are studied, such as high fidelity and high resolution data acquisition, real time communication and unaddressable link of acquisition units and multi-media hybrid telemetry measurement. The system consists of a 31-bit high-resolution acquisition unit chain, 3 G/4 G wireless communication and wired communication cross-data management station, a portable main control station, and a set of software. Comparing with the 428XL seismic exploration system of Sercel and the test in 1 km(2) 3D seismic exploration show that this system has advantages of light equipment, stable performance, high resolution and good quality of data. It enhances the core competitiveness of seismic exploration technology of our country.
