深水钻机K型井架稳定性数值模拟研究
|
摘要
针对K型井架整体防护性较弱、在恶劣的海洋环境下可能发生失稳的问题,以南海某深水半潜式平台在作业工况下的运动响应为背景,对浮式平台配套的K型井架进行了稳定性研究。平台动边界对井架产生的动载荷等效为惯性力施加在井架上,同时考虑海洋风载、平台倾斜使井架受到的重力横向分量以及平台升沉引起的附加动载荷,利用有限元模型计算了井架的受力状态和整体稳定性;研究了各杆件在轴力和双向弯矩下的局部稳定性;将前大腿等效为弹性支撑梁,在轴向压力作用下进行了屈曲分析;对比了该井架用于陆地钻井的稳定性质。结果表明,海洋环境载荷使K型井架的稳定性有较大程度降低,但仍满足该工况的稳定性要求。
To address the overall weak protection of a K-type derrick and its potential instability in a severe marine environment,taking the motion responses of a deep-water scmi-submcrsible drilling platform under operation regimes in South China Sea as the research setting,a study was thus carried out on the stability of a K-type derrick that is associated with floating drilling platforms.The dynamic load induced by the dynamic boundary of the platform is exerted on the derrick,which can be equivalent to the inertia force that is applied to the derrick.The transverse component of the gravity imposed on the derrick that is attributed to oceanic wind loads and the tilting of the platform as well as additional dynamic loads induced by heaving motions ofthe platform was considered.This was essential for computing the force-bearing states and overall stability ofthe derrick using a finite element.The local stability of various member bars under axial forces and biaxial bending moments was investigated.Further,the front legs of the derrick are equivalent to elastic support beams,and buckling analyses were conducted under the influence of axial compressive forces.Further,the stability properties of this drilling derrick used for land rigs were compared.Results demonstrated that ocean environmental loads decrease the stability of K-type derrick considerably;however,the stability requirement for the above-mentioned operation regimes is still satisfied.
