摘要:

在条件复杂的深油气井井下作业时,封隔器需要具备良好的耐高温、耐高压和密封性能,以此来提高封隔器的使用寿命。相较于传统的K344叠层钢带封隔器,K344波纹状钢骨架封隔器可以有效地减少内外胶筒中部应力,使中部受力更均匀,并可同时降低肩部受力。利用ABAQUS软件,对K344波纹状钢骨架封隔器的坐封过程进行有限元仿真分析,从结构和材料两方面对钢带的受力情况进行研究,并通过仿真分析优选出钢带的最优厚度以及钢带的最优材料。优化后的封隔器能够更好地适应深油气井的作业要求,提供了一种新的扩张式封隔器设计思路。

Abstract:

In the complex deep oil and gas well downhole operation, the packer needs to have good high temperature resistance, high pressure resistance and sealing performance, so as to improve the service life of the packer.Compared with the traditional K344 laminated steel belt packer, the K344 corrugated steel frame packer can effectively reduce the stress in the middle of the inner and outer rubber barrel, make the force in the middle more even, and reduce the force on the shoulder at the same time. In this paper, by using ABAQUS software, the K344 corrugated steel skeleton packer setting process in finite element simulation analysis, from two aspects of structure and material to the force of the steel strip was studied, and a simulation analysis with the optimal thickness of the strip, and the optimal material for steel belt optimized packer could better adapt to the job of deep oil and gas wells, provided a new expansion packer design thinking.

Key words: K344 packer, Corrugated structure, Simulation analysis, Steel strip thickness, Structure optimization
