Design Technology Of Survey System For Tahe Oilfield Development

At present,with the deepening of the degree of oil and gas exploration and development,a large number of domestic old oil region has entered the later period of development.Geared to the needs of oilfield development of seismic exploration technology,more and more get the wide attention of lard companies especially in the potentiality of the old oil region,using development seismic technology can effectively extend the service life of oil field,helps to identify and find the new reserves,reduce dry Wells and low production Wells,thus achieve increase reserves,reduce cost and improve recovery factor to improve overall economic efficiency.Tahe oilfield is located in the south of tianshan mountain,the north rim of the taklamakan desert gobi desert region,is located in the xinjiang uygur autonomous region's kuqa and luntai,tectonic position of shaya uplift in northern tarim to gram coolers raised in middle west.Based on the survey system technology at home and abroad under the condition of extensive research,seismic data and in combination with field construction production completed,carried on the thorough research and comparison.With the continuous development of tahe oilfield,the previous conventional 3D seismic data of low density,narrow azimuth,especially in tahe area small crack body piercing recognition is difficult,characterization is not fine,unable to meet the needs of oilfield development further.Through research,put forward on the basis of the analysis of the exploration results,the application of acquisition footprints suppression technology,high resolution bin size design technology,high signal-to-noise ratio design technology,and the arrangement of wide azimuth frequency coverage technology research achievements,such as the length of the argument in tahe oilfield in the small scale of the joint body piercing and deep karst reservoir seam hole system,and demonstrates the overall experience formula and the three-dimensional development seismic exploration cost has carried on the comprehensive consideration.Through the application,further improved the area's survey system design method,ensure the quality of seismic data,from the point of effect,exploration area to further improve the image quality,more accurate to seam hole type reservoir characterization.
