Study on the engineering geological properties of drill hole in North Yellow Sea

摘要

The North Yellow Sea basin was located in the middle of the North Yellow Sea. It was possible to find oil and gas reservoirs in this area according to different researches. It was also an oceanic area studied little. In this paper, the engineering geological properties of a drill hole samples collected in the middle of the North Yellow Sea Basin was studied, which could provide basic data for engineering construction and oil and gas exploration and development in this area. In result, stratum of the study area can be divided into 9 units; the mechanical properties of cohesive soil are poor, which have the feature of high compressibility and low shear strength; Granular soil, especially unit 9, has high strength and good engineering property, which is appropriate for use as bearing stratum for drilling platform and other ocean engineering.
