技术领域technical field
本实用新型涉及一种模拟管形件变形行为的试验装置,特别是关于一种模拟深水环境下,测试油管柱热变形、热应力的模拟试验机。The utility model relates to a test device for simulating the deformation behavior of tubular parts, in particular to a simulation test machine for testing the thermal deformation and thermal stress of oil pipe strings in a simulated deep water environment.
背景技术Background technique
在深水油气井测试作业中,普遍存在的异常高温问题会导致管柱破坏、封隔器失效、控制头上移、井口上升等作业事故,对海洋石油生产造成严重的影响。由于作业中的油管柱内外壁存有较大温差,以及目前对不同温差、材质、尺寸油管柱热变形规律研究还不够深入,因此研究不同温差、材质、尺寸油管柱热变形更具有应用价值和实际意义。In deepwater oil and gas well testing operations, the ubiquitous abnormal high temperature problems will lead to operational accidents such as pipe string damage, packer failure, control head upward movement, and wellhead elevation, which will have a serious impact on offshore oil production. Since there is a large temperature difference between the inner and outer walls of the tubing string during operation, and the current research on the thermal deformation of tubing strings with different temperature differences, materials, and sizes is not deep enough, the study of thermal deformation of tubing strings with different temperature differences, materials, and sizes is more valuable and valuable. practical meaning.

The shape and size of the measured object are limited: The structure of the measured object is designed on the basis of the standard sample in the national standard for the determination of the material linear expansion coefficient, that is, a slender rod with a minimum length of 25±0.1mm and a radial dimension between 3 and 10mm. , these special-purpose dilatometers are not suitable for measuring mechanical parts with complex shapes; 2. The measurement temperature range is too wide: for the measurement of the thermal deformation of the tubing string, because the temperature range during operation is not large, the measurement and control temperature Measurement instruments with a wide range cannot achieve high-precision measurement; 3. The direction of measurement is single; 4. The working environment of the tubing string cannot be fully simulated.
因此,本领域迫切需要一种能够充分模拟深水环境下油管柱热变形的测量装置来解决上述问题。Therefore, there is an urgent need in the field for a measuring device capable of fully simulating thermal deformation of tubing strings in deep water environments to solve the above problems.
