High Resolution Seismic Data Processing Technology And Its Application In Reservoir Prediction

With the improvement of exploration technology,increasing the resolution of seismic data is demanded by the interpreter.Due to the impact of the earth filter attenuation and absorption of the medium,the high frequency seismic wave is mainly absorbed with resulting in loss of energy and phase distortion.So enhancing high frequency part of the seismic data to improve the image quality is necessary and needed..As we all know,the wider bandwidth of seismic data and the higher in the frequency,the higher the resolution of seismic data when the of seismic data acquisition technology is not greatly improved,high-resolution seismic data processing is to compensate for the formation of one of the most attenuation effective way.Only when there is a high resolution seismic records,we can clearly identify its smaller geological boundaries,explain and predict hydrocarbon reservoirs to meet the needs.Ways and means to improve the resolution of seismic data a lot,but the processing and interpretation combine to explain the requirements and objectives of high resolution seismic data processing constraints,is to choose a high-resolution processing method,and determine the treatment effect of basis and purpose.In this paper,we study the method to improve the resolution,and study the principle of self-adaptive inverse Q filter and then using the programming to achieve it,then applied to process the actual data.According to oil and gas reservoir recognition and the requirement of prediction and the real geological achievement,analysis the rationality and applicability of seismic data processing,study the rationality of processes and parameters,With the new high resolution data processing carried out fine reservoir interpretation and hydrocarbon prediction,through high resolution processing after application in seismic inversion and seismic attribute analysis,combined with the actual geological conditions provides a new interpretation and evaluation of reservoir based on high resolution processing results for the study area.This study is mainly aimed at the Da10 area of Xinjiang,Though the process the original data's basic frequency increase from 30 Hz to 46 Hz,after processing the target stratum event become more thin.Improve the reliability of data interpretation.4 pieces of high quality areas in DA10 well area in total of have been implemented.The favorable reservoirs are: DA13-DA14-YAN001-XY2-YAN002 wells region,DA11 well and the South West region,YB2 wells region,DA10 well and south region.
