Abstract

In order to solve the problem of "gas explosion" at the end of common rubber cylinder in the process of high temperature, high pressure and gas drive operation, the rubber cylinder with new structure suitable for 51/2in casing pipe is developed. The "M" type single rubber cylinder structure is adopted in the new structure rubber cylinder, and the "gas explosion" problem of the end gas in the low-pressure side is solved by setting the double-layer staggered slotted steel cover to prevent outburst. The finite element method is used to simulate the setting of the rubber cylinder, and the structural parameters of the new rubber cylinder are obtained by single factor analysis and orthogonal optimization, simulation test and seal test were carried out to verify the sealing performance of the rubber cylinder. According to the actual working condition, the simulation test results and seal test results show that the sealing capacity of the packer reaches 50MPa under the temperature resistance of 120℃, and the end steel cover is fully opened to wrap the rubber cylinder, which meets the operation requirements of high temperature and high pressure gas injection packer.

高压注气封隔器单橡胶筒的设计与性能研究

为解决普通橡胶筒在高温、高压、气驱作业过程中末端发生“瓦斯爆炸”的问题，研制了适用于51/2in套管的新型结构橡胶筒。新结构胶筒采用“M”型单胶筒结构，通过设置双层交错开槽钢盖防止爆发，解决了低压侧末端气体“瓦斯爆炸”问题。采用有限元法对橡胶筒的设置进行模拟，通过单因素分析和正交优化得到新型橡胶筒的结构参数，并进行模拟试验和密封试验，验证橡胶筒的密封性能。根据实际工况，模拟试验结果和密封试验结果表明，该封隔器在120℃耐温条件下的密封能力达到50MPa，端钢盖完全打开包裹橡胶筒，满足高温高压注气封隔器的运行要求。

期刊介绍： International Journal of Numerical Methods for Calculation and Design in Engineering (RIMNI) contributes to the spread of theoretical advances and practical applications of numerical methods in engineering and other applied sciences. RIMNI publishes articles written in Spanish, Portuguese and English. The scope of the journal includes mathematical and numerical models of engineering problems, development and application of numerical methods, advances in software, computer design innovations, educational aspects of numerical methods, etc. RIMNI is an essential source of information for scientifics and engineers in numerical methods theory and applications. RIMNI contributes to the interdisciplinar exchange and thus shortens the distance between theoretical developments and practical applications.
