Abstract:Carboniferous is the important hydrocarbon bearing strata series in Santanghu basin.As it is not easy to acquire the effective reflections for the deep target in the seismic exploration,there is no clear understanding for the inner structure of Carboniferous in the basin,restricted the oil gas exploration progress.Taking the field sounding acquisition with the multi-frequency band and high S/N ratio and generalized reverse 2D constraint inversion as the core,the new filed sounding technique with integration of acquisition,processing and interpretation was introduced in the paper and then used in the oil gas exploration in Malang Depression in the Basin.The application results showed that this method can reveal the multi sets of strata in Carboniferous and the distributed volcanic rocks inside the strata.The paper also pointed out that the Haerjiawu Group low resistivity stratum is the hydrocarbon source beds developed from the shaly clastic rocks,and the layers with high resistivity electricity characteristic in Kalagang Group and Batamayineishan Group are favorite reservoir developed from the volcanic rocks,which is proved by the drilling result.
