Applicability Analysis and Mechanical Characteristics of Deep Water Suction Pile

Abstract

Abstracts The seabed soil in the deepwater surface has the characteristics of soft soil and low bearing capacity, the suction pile has the characteristics of high bearing capacity, it has broad application prospects in deep-water oil and gas drilling and production. Through the test experiments of lateral bearing capacity of suction pile after installation in place and numerical simulation of maximum stress and maximum displacement of suction pile wellhead, it is found that the bending moment load will cause the suction pile to be offset, and with the increase of the bending moment load, the wellhead offset increases, and the gasketed end shifts downward; with the increase of the tilting angle of the suction pile, the maximum transverse displacement and the maximum stress of suction pile increase, and the suction pile can protect the conductor from deformation effectively. Deformation. This study can be an important reference for the construction of wells with suction piles in deep-sea soft ground.
