Abstract:Total 189 blocks of 3-D seismic data acquisition have been finished in Shengli Oilfield.In order to integrative studying regional geologic structures and role of oil accumulation,it is necessary to implement the data processing joining several 3-D seismic surveying blocks together.The paper summed up a set of basic flow for data processing joining several 3-D seismic surveying blocks together suitable for complex areas after analyzing this real data processing.During this processing,we adopted relative processing methods and tools aimed at inconsistence between blocks,which made joined 3-D data blocks have good consistence of phase and porosity and natural and reasonable frequency and energy (or amplitude),it also made the geologic feature such as overlap,unconformability,fracture and pinchout have good reflection on the sections.It is seen from total effects that the geologic feature in whole region is abundant,having complete beds and higher signal-to-noise ratio and continuity,which laid a good foundation for improving interpretation precision of seismic data and successful drilling rate.
