Research On The Deep Igneous Rock Target Processing Technology In Xujiaweizi

Xujiaweizi depression is the focus of the deep gas exploration area of ancient central uplift of Songliao Basin east, and special lithology of volcanic geology of abnormal development, However, due to the seismic data quality restrictions, the lack of truly fine for comprehensive geological study of the seismic profile, the goal of making the implementation of the degree is far from enough, for further deep volcanic goal processing technology research, improve the quality seismic data, as explained The provision of more sophisticated, accurate and reliable seismic profiles, lithology forecast to meet projected demand and reservoirs it is of immense significance.Given the deep igneous rock reflection of irregular wave field and the complexity of the data processing area to bring a lot of difficulty, has long been the subject is difficult to overcome, so the research and development projects in this is more practical value.This paper Songliao Basin in northern Xujiaweizi under complicated geological conditions of the characteristics of seismic data, respectively, the static correction, deep energy compensation, deconvolution, DMO stack and pre-stack time migration, and other technology for the study, Test the methods on the basis of detailed, careful analysis and study, give full play to the advantage of the technology, summed up a set of practical value, for deep geological objectives of the processing technology, information igneous rocks in this area has been made in the handling of comparison Good results, and promote the formation of a broad value of the processes for the handling of similar information laid a solid foundation can be reliable.
