Abstract
In this paper loads on experimental equipment,which were formed by built-in composite perforating units under the condition of high temperature,were analyzed by numerical simulation technology.T he specific process is as follow s:Firstly,the composite perforating unit experimental equipment used for lab experiments was heated up to 190 ℃ in Perforators Inspection Center of PetroChina, and then the fluid-solid coupling numerical simulation calculation of blasting shock was carried out.The results showed that the internal stress of the structure increased and the structure loading capacity of the equipment decreased under the condition of high temperature.On the basis of the results,the composite perforating unit experimental equipment that can be used under the condition of high temperature was designed and manufactured.With the help of this new equipment,the contrast tests of a certain type of high temperature composite perforating unit were carried out under the room temperature and high temperature(180 ℃ and 150 h).It is found that the peak pressure decreased 11.1% and the duration time decreased 9.8% under the condition of pressure no less than 30 M Pa,w hich lay the foundation for inspection and evaluation of high temperature composite perforators used in oil field.关键词
