Abstract:The paper introduced the seismic acquisition techniques in finishing Iran seismic acquisition project in recent years, among which including charge-free usage of network resource, shooting by multiple sources, flexible geometry design and improvement of receiving method, achieving better results: ①the usage of charge-free network resource not only provides technical scheme to A Party in the shortest time, but also fulfills more precious appreciation to the project operation, improving the effect of special geometry and geometry variation in a whole; ②joint shooting by multiple sources improved data quality; ③flexible design of geometry is a necessary tool ensuring data quality in complex area while acquiring better economic benefit; ④the development of geophone-planting tool made the data quality have dramatic progress. The geophone plant in mountains area should follow the principle getting good coupling of geophone.
