摘要
立管技术是深水资源开发的关键技术之一。管中管钢悬链线立管具有同心的外管与内管，其外管提供机械保护，内管提供油气通道，内、外管之间按照一定的距离安装扶正器以保护绝热材料，在深水油气开发中具有较大的应用价值。充分考虑在位立管承受的复杂载荷条件泡括动边界、波浪与海流载荷、立管自重、海水浮力、管内外静压力），以及整体和局部非线性因素（包括摩擦、滑移、接触、间隙等），采用时域有限元软件ABAQUS实现管中管钢悬链线立管的建模与非线性动力分析。
Riser technology is one of the key technologies to exploit deepwater resources. The deepwater pipe-in-pipe steel catenary riser is comprised of concentric inner and outer pipe, the inner pipe carries the production fluids and is thermal insulated, whilst the outer pipe provides mechanical protection, and the centralizers are spaced at certain intervals over the full length of the riser to prevent the thermal insulation material in the annulus from being crushed. It plays an important role in oil and gas development in deepwater. In the present study, nonlinear dynamic analysis of deepwater pipe-in-pipe steel catenary risers with centralizers is performed using the time domain solver ABAQUS. Complex loads conditions applied to the in-situ risers including dynamic boundary conditions at the top end, wave and current loads, self-weight, buoyancy force, external hydrostatic pressure and internal pressure, as well as the global and the local nonlinear factors including friction, sliding contact and clearance are all accounted for. This paper presents reference for analysis and design of risers engineering in deepwater.
