Seismic Fine Structural Interpretation Of Nantun Group In Northern Wuerxun Concave

In this paper, using a combination of sequence stratigraphy, structural geology analysisof data on structural characteristics Nantun group of Wuerxun and tectonic evolution historyconcave depressions black north south times times depression conducted in-depth anddetailed analysis and research, while Depression in Northern Uganda Wuerxun combinationof lithology, logging features, such as the distribution area were favorable facies prediction,this study may provide protection for the precise sequence of divided areas for future oil andgas area Exploration and development to provide a theoretical basis, have practicalsignificance.The study will be divided into two Nantun third-order sequences eight four sequences,and each four systems tracts are fully developed, the interface of the two third-ordersequences located lithology and electric conversion face, South Second cycle trend is positive,one for anti-cyclic trend south, under the truncated part of the interface.Detailed interpretation of seismic structure, build a three-dimensional geological modelof the subsurface that best meet the final distribution of rational analysis Nantun constructedin northern Uganda. In northern Uganda is surrounded by low-lying south western times witha steep slope, the central uplift belt, Surennuoer fault zone, with a deep depression, easterngentle slope with five secondary structural elements in the basis of conventionalthree-dimensional seismic interpretation on the use of software to create fine Landmarksynthetic seismogram calibration layers; Three-dimensional coherence tomographytechnology accurately implement distribution; Meanwhile, the application wells and seismiccontrast technology is not only beneficial structural interpretation of seismic data, well logdata but also for the comparison provides a more effective basis for expansion the Nantungroup space exploration and development and evaluation, looking with favorable reservoirdevelopment and gas distribution, oil and gas field encryption adjustment guide block ispreferable to explore the favorable reservoir provides a lot of information.Results of this study to promote the development of this area will play a role, but theresults for the high-frequency sequence stratigraphy, structural interpretation of the furtherdevelopment of small faults technology deeper significance.
