Gravity and magnetic dynamite vibroseis joint forward inversion technology in Erlian Basin application in deep target exploration
Erlian Basin is rich in oil and gas resources.As the main source layer of the basin.the pre-Cretaceous has long been proved to be oil-bearing.However,the overall exploration degree of the Gaolihan Depression and its periphery in this basin is low,and the small number of 2D earthquakes completed in the early stage are only confined to several independent depressions,which cannot be connected,and the lack of understanding of the overall geological structure of the area has not achieved significant results in oil and gas exploration so far.Pre-vious studies have found that the pre-Cretaceous strata in Erlian Basin are widely distributed,the source rocks have high organic matter abundance and maturity,and are in the mature-condensate wet gas stage.The drilling degree of the pre-Cretaceous strata is low,and the exploration of oil and gas in the pre-Cretaceous strata can a-chieve a breakthrough in the exploration of new strata in Erlian Basin,and expand the strategic replacement of new strata in Erlian Basin.In recent years,high-precision gravity and magnetic exploration has restored the ori-ginal features of the pre-Cretaceous basin by means of specific processing and interpretation techniques such as gravity and magnetic well vibration combined forward and inversion,which is expected to open a new chapter in the study of the deep geological structure of Erlian Basin.
