| Summary: | With the prosperous development of electronic science and technology, electrical logging technology has been widely used in the process of oil exploitation. Seismoelectric logging is one of the many electrical logging methods, which has some unique advantages compared with other logging methods. At present, there are a lot of theoretical research on the seismoelectric logging at home and abroad, but due to some engineering problems has not been solved, practical instrument is not yet come into being. The acquisition of seismoelectric signal is one of the most difficult problems in the practical application. In this paper, a set of seismoelectric signal acquisition system based on SPI bus is designed to solve this problem. Experiment show that the system basically meets the demand of signal acquisition in seismoelectric logging
