摘要
为了准确了解O圈应用过程中的密封性能及密封渗漏规律,通过实验定量测得O圈在高温高压环境中,一段时间内的渗漏水汽量。将装有无水硫酸镁的试管与O圈实验工装连接,一并放入烘箱内进行长时间烘烤,一段时间后取出工装,测得试管中试验前后药剂的差值,即为O圈渗漏的水汽量。实验结果测得,直径Φ12mm×Φ1.8mm的小O圈在单边压缩量为0.45mm情况下,渗漏量最少为35.25mg/2周;直径Φ108mm×Φ3.55mm的大O圈在单边压缩量为0.8mm情况下,渗漏量最少为456.19mg/2周。研究结果表明,O圈渗漏量与直径有正相关的联系,渗漏水汽量随着O圈直径的增大而增加。本次O圈渗漏水汽量定量实验研究可为高温高压机电一体化油田工具设计和现场作业过程中的产品寿命控制提供理论参考。
In order to accurately understand the o-ring application process, sealing performance and sealing leakage law. The amount of water vapor leaking from O-ring in a period of time under high temperature and high pressure was quantitatively measured through experiments. Connect the test tube with anhydrous magnesium sulfate and the o-ring test fixture, and then put it into the oven for a long time baking. After a period of time, take out the fixture, and measure the difference between the reagent before and after the test in the test tube, which is the amount of water vapor leaking from the O-ring. The leakage of a small O-ring with diameter of φ 12mm×φ 1.8mm was at least 35.25mg/2 weeks under the condition of unilateral compression of 0.45. The large O-ring diameter of φ 108mmX φ 3.55mm had a minimum leakage of 456.19mg/2 weeks at 0.8 unilateral compression.The results show that there is a positive correlation between the leakage amount of O-ring and diameter, and the leakage amount of water increases with the increase of o-ring diameter. The quantitative experimental study of o-ring leakage water vapor quantity can provide theoretical reference for the tool design and product life control in the field operation process of HHT mechatronic oilfield.
