High Precision 3D Seismic Acquisition Technology Research And Application In East Old Oil Region Of Shengli Oilfield

After 50 years of exploration and development,the east old oil region of Shengli Oilfield,on the whole,is at its most reserves found that late.But in recent years with the development of the theory of exploration and exploration technology,The old oil region of Shengli Oilfield has great exploration potential.The main exploration direction in the area is: complex fault block oil gas reservoir,all kinds of lithologic oil and gas reservoirs,deep reservoirs,as well as the fine exploration of igneous rock Development Zone,etc.East old oil region complex of subtle reservoir exploration and development need high precision seismic exploration technology as support.Acquisition as the first part of seismic exploration,is key factor to obtain high quality seismic data,in view of the old oil region east of Shengli Oilfield high precision 3 d acquisition technology is based on the geological characteristics of the old oil region and the difficulties of the exploration and development,starting from the geological target body,formed a comprehensive parameter argumentation based on geological model;Observation system for quantitative analysis and optimization technology;The forward modeling technology based on illumination analysis;Meet the adequacy of the observation system,symmetry,uniformity and continuity.To win the eastern old oil region,this paper analyzes the characteristics of surface sediment and sediment;Through the study of various surface structure survey methods,suitable for the region was the surface investigation method,has realized the fine surface structure modeling.Based on explosion theory,research and development of high energy,high efficiency the source column,after constantly test and improvement,to improve the effect of excitation energy and frequency.On receiving link,through the detector performance index,indoor test and comparison of experimental data,which is suitable for high precision three-dimensional optimization of high performance detector,to form the broadband receiving technique of high fidelity.Through the application of the above technology,Shengli Oilfield in the eastern old oil region of seismic data quality on a new stage,the old oil exploration and development provides a strong guarantee.
