Abstract：This article involves seismic techniques in surface-complicated area of Shengli Petroleum Administration. New technical measures are taken to cope with some tough problems in surface survey, geophone planting, source type choosing and loeating, environmental noise, layout chart design of seismic exploration in some surface-complicated areas in plain. New measures include: ·Reasonable surface survey is taken to achieve desirable result. ·Geophones are improved to be suitable for various surface conditions and to counter 50Hz noise. ·Manual plus semi-mechanized drilling technology is used to conveniently have drilling sites. ·Shaped charge is introduced to ensure safty application. ·Field conditions are considered sufficiently in layout chart design to make it more reasonable. These techniques have shown obvious effect in their application in recent years, they may be considered as successful experience of seismic exploration in plain where surface conditions are complicated enough.
