摘要
封隔器在石油生产中起着重要的作用,所以有必要对其密封性能和抗压能力进行验证。文中设计了一种用于封隔器试验的高温高压井筒,通过配备相应高压泵和加热循环装置,可以有效模拟井下的高温高压环境,验证最大压力100 MPa和最高温度200℃情况下封隔器的性能。通过Pro/E和ANSYS Workbench联合仿真,根据安全系数的目标条件对井筒的尺寸进行了优化,实现了用最小的尺寸满足温度和压力要求。井筒尺寸确定后,分析了井筒在不同温度和压力下的受力和变形情况,并且得出了相应的输入输出关系。
Packer plays an important role in oil production, so it will be necessary to verify the sealing performance and capacity a- gainst pressure. In the paper, a high temperature and high pressure （HTHP） tubing for packer testing is designed. With high pressure pump and heating circulation device simulating the HTHP environ- ment, the tubing can validate the performance of packer under the condition that highest temperature is 200 ℃ and highest pressure is 100 MPa. By the co-simulation of Pro/E and ANSYS Workbench, sizes of the HTHP tubing are optimized in accordance with safety factor, which realize the minimum sizes for temperature and pres- sure requirements. After determining the dimensions of the HTHP tuning, the stress and deformation under different temperature and pressure are analyzed. Furthermore, the corresponding input-output relations are obtained.
