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 petroleum production, so it is necessary to verify its sealing performance and compressive capacity. In this paper, a high-temperature and high-pressure wellbore designed for the packer experiment is designed. Through the corresponding high-pressure pump and heating cycle device, the high temperature and pressure environment in the well can be effectively simulated. The maximum pressure of 100 MPa and the maximum temperature of 200 ℃ are validated. Performance. Through the co-simulation of Pro / E and ANSYS Workbench, the wellbore size is optimized according to the target conditions of safety factor, which meets the temperature and pressure requirements with minimum size. After the wellbore size is determined, the stress and deformation of the wellbore under different temperatures and pressures are analyzed, and the corresponding relationship between input and output is obtained.
