Jiyang Depression has stepped into medium-high exploration stage，and the discovered reserves distributes in shapes of several circles. There are still many reserves blank areas on the migration pathway from hydrocarbon kitchen to discovered oil-gas fields，and there is big potential for the undiscovered traps in blank area including lithologic traps，structural-lithologic traps，and unconformity traps to capture and accumulate hydrocarbon into reservoirs. By analyzing the exploration process of the lithologic traps in the saddle structure of Gudong-Hongliu Oilfield and the north slope of Kendong Swell，the inspiration from trap exploration on petroleum migration pathway and proposes of research ideas were described briefly. Taking the research process of the structural traps in the periphery area of Jiangjiadian Oilfield between Linnan hydrocarbon kitchen of Huimin Sag and Qudi Oilfield as an example，the main research idea and methods were introduced.The bridge between hydrocarbon kitchen and oil-gas field were built up through oil-source correlation，the target strata were built up by analyzing hydrocarbon reservoirs，the possible conductive layers and trap types were identified by studying the sedimentary environment，and the exploration targets were determined by effectively identifying and evaluating the traps. The summary and proposal of the research ideas and methods of“evaluation of traps on migration pathway from source kitchen to oil and gas field”are significant to guide the hydrocarbon exploration in the future.
