摘　　要：为更准确地计算出打桩隔水导管的最小入泥深度,充分考虑泥线以下地质特征、泥线以下地层的承载能力及隔水导管的力学性能等参数,在理论研究的基础上建立隔水导管最小入泥深度计算方法,并根据某油田的工况条件进行了理论计算,从而得出针对该区块24in、30in两种规格隔水导管在不同井口载荷下的最小入泥深度,对该区块现场打桩作业有一定的指导意义。In order to more accurately calculate the minimum mud penetration depth of the pile riser,full consideration is given to the geological characteristics below the mudline,the bearing capacity of the stratum below the mudline,and the mechanical properties of the riser.The calculation method of the minimum mud penetration depth of the conduit,and theoretical calculations based on the operating conditions of an oil field,so as to obtain the minimum mud penetration depth of the 24in and 30in two-layer risers under different wellhead loads in the block.The site piling operation in the block has certain guiding significance.
