Through analysis of the region of the large number of high-resolution shallow stratigraphic section survey data , combined with the geological drilling data , shallow ancient river study area , the acoustic stratigraphy reflection characteristics , sedimentary characteristics , as well as the scale of the regional distribution and burial depth described the research , described the relationship between the formation of shallow paleochannel regional sea-level change . The top of the Liaodong Bay shallow area is rich in oil and gas resources , and has broad prospects for development . Shallow ancient river as the area wider distribution of the potential disaster of geological body , has an important impact on the development of oil and gas resources . Marine disasters geological formation and development of its natural environment of closely related . In this paper, based on the region 's large number of environmental , geological survey data collected from hydrometeorological , topography , depositional environment , acoustic stratigraphy , engineering geology and tectonics , earthquakes and other various aspects of the study area, marine engineering environmental elements analyze, summarize and reveal the general characteristics of the study area, marine engineering environment . On this basis , combined with the shallow paleochannel characteristics , its engineering geological disasters evaluation .
