Abstract: An geophysical profile has been collected from Dangbi Town to Baoqing County(DB02) in the east part of Heilongjiang Province. After the analysis of the geophysical characteristics in the study area, and according to gravity Euler deconvolution calculation results, DB02 geophysical profile could be divided into sections within 9 fractures and 7 structure regions. Sedimentary basement and oil-gas prospect areas were calculated and forecasted. The results show that the low-resistivity area in the eastern Boli basin is not a conducive area of oil, but a favorable area for coalbed methane; Baoqing depression have nappe structure in the upper, while the low resistance reservoir area in lower are suitable for oil and gas accumulation.
