The Identification And Evaluation Of Excellent Source Rockin Tanan Sag And Nanbeier Sag

This article analyses the structural characteristics of the basin, the tectonic settingof the study area, basement and cover layer characteristic from the uranium ore-forming geological conditions.Focus on the analysis of the mechanism of uranium mineralization,uranium source of the study area,migration and sedimentation environment starting from the genesis of mineral deposit.The seismic data of the study area is interpreted,the wave group characteristics, structural characteristics, fault characteristics, stratigraphic features, ancient structural characteristics and tectonic evolution of the objective reflective layer are analyzed in detail.Basing On the lithology of the study area,and by thecontinuous tracking of the profile combined with drilling lithology,two igneous rock and two ancient river are identified.On the seismic facies analysis of the study area seismic data and the calibration of the single well Sedimentary facies and seismic facies,seismic phase is transformed into the sedimentary facies.Finally,basing on the comprehensive analysis of sedimentary facies, gamma anomalies well distribution, source dibection,front line of the interlayer oxidation zone, oil and gas channel and the terrain, cover structure and ore controlling fault of the bottom of ore-bearing strata, the favorablearea of uranium mineralization is predicted.The purpose of this paper is to study the regional geological structure of the western slope zone of the northern Songliao Basin, analyse uranium ore-forming geological conditions,mineral deposit types,mineral deposit characteristics and the genesis of mineral deposit using the existing old2seismic data.We can comprehensively analyse uranium mineralization favorable sand bodies through the analysis of abnormal distribution, tectonic evolution, sedimentary facies, structure distribution, fault distribution, tectonic, lithologic oil and gas channel, and redox environment, prediction of sand body, old channel identification and other technical means and search the mineralization favorable areas according to uranium favorable reservoir conditions,narrowing the favorable target for uranium exploration.The integrated exploration technology combined use of drilling, logging, seismic facies can hep to improve the accuracy of the sandstone-type uranium deposits developed exploration, guide the rational layout of the drilling, reduceexploration costs and shorten the exploration period.Further study of the non-oil and gas exploration especially the metal deposit exploration of new energy technology research making full use of the existing seismic old data,can effectively save exploration cost, breaking the restriction of the oil and gas resources, increase the income of the non-oil and gas resources, develop new energy, strengthen national defense and promotethe long-term development of oil field at the same time.
