The design of the Column testing system under the high temperature and pressure
Abstract
According to the indoor tubing string hot deformation simulation and the model of finite element simulation, establishing the software which analysis the thermal deformation of the oil column in high temperature and deep water, we can provide a reasonable choice of reference deep water environment for the high-temperature tubing string develop a security assessment software, which can meet the engineering needs of deepwater production and testing of the string security, provide conditions for designing the column in the actual project and security analysis. Achieve the key objectives of the technical content issues, has great significance to ensure the safety of deepwater gas field.
In this paper, we analysis the relationship between the deformation、 stress、strain and temperature of oil column, and then select the appropriate testing programs and determine the related sensors 、collecting equipments and some software.Keywords: deformation,sensors, dta Acquisition
