摘要
为了适应老油田精细分层注水需求,应加强现有封隔器结构设计的合理性。针对扩张式封隔器的胶筒长度比较长,扩张时各部分扩张不均匀,肩部容易破坏的问题进行了研究。根据扩张式注水封隔器坐封原理,采用了有限元的方法,以业内具有较高认可度ANSYS Workbench15.0有限元软件,对一种具有10 mm补偿结构的K334-112封隔器进行了力学分析。对输出结果分析表明,胶筒在各个部分的受力情况和位移状态都是不均匀的,应力集中始终出现在胶筒肩部,在设计胶筒时如果能改善应力集中部分的性能,将使得封隔器的设计更加合理。这样运用有限元的方法分析优化封隔器的结构与传统的使用实验的方法相比,更能适应现在高速发展的机械结构研究邻域,使得封隔器制造商能有更高的行业竞争力。
In order to meet the needs of the fine oil injection in the old oilfield,it was necessary to strengthen the rationality of the existing packer structure design. The length of the drum was longer for the expansion packer,and the expansion was uneven and the shoulder was easy to destroy. According to the principle of the expansion of the water injection packer,the finite element method was adopted,and the K334-112 packer with 10 mm compensation structure was carried out with ANSYS Workbench15. 0 finite element software to carry on mechanical analysis. The analysis of the results of the output showed that the force and displacement states of the plastic cylinders were uneven in all parts,and the stress was always concentrated on the shoulder of the cylinder. If the performance of the stress concentration part can be improved when the cylinder is designed,the design of the packer was more reasonable. This method of using finite element method to optimize the structure of the packer compared with the traditional method of using the experiment will be more adaptable to the now high-speed development of the mechanical structure of the neighborhood,to make the packer manufacturers have a higher industry competition force.
