Development of Mechanics Behavior Simulation Experimental System for Deep-Water Drilling and Production String

用试验手段对深水钻采管柱进行力学行为模拟，以获得管柱的受力变形规律，对于保证各种钻采管柱的可靠性以及深水钻采作业的安全性具有重要意义。为此，研制了能够模拟深水条件下管柱力学行为的特殊试验装置——深水管柱力学模拟试验系统。该系统可以模拟0～3000m水深的海洋环境，可对被试验的管柱施加内外压及轴向力载荷，配备相应的附件后能实现横向力及转矩的加载。该装置具有加载压力高、响应及时、内部拆装空间大、操作简单、数据采集可靠等优点。

Simulated the deepwater drilling string mechanics behavior and obtained the stress deformation distribution of string using experimental method is of great significance to ensure the reliability and safety of all kinds of drilling and production string in deepwater operations. In order to achieve this purpose,a special experiment device was developed which is called deepwater drilling and production string simulation experiment system. The equipment can be used to simulate the marine environment of 0~3 000 m water depth and can apply both inside and outside pressure and axial force to simulation string at present and can also realize transverse force and torque load after equipped with corresponding attachments. The experiment device has several advantages sueh as high load pressure, quick response,large dismounting space, simple operation and reliable data collection.
