摘要（英）：

The invention is applied to the field of petroleum or chemistry and energy or mine fields and discloses a high-temperature and high-pressure digital back-pressure control system and method. The high-temperature and high-pressure digital back-pressure control system comprises a back-pressure valve body, a first connecting line, a three-way part, a second connecting line, a third connecting line, afirst cooling pipe, a second cooling pipe, a fourth connecting line, an automatic back-pressure tracking pump, a fifth connecting line, a back-pressure feedback component and a control display system.The back-pressure valve body is connected with a first connector of the three-way part through the first connecting line. The second connector and the third connector of the three-way part are connected with the first cooling pipe and the second cooling pipe through the second connecting line and the third connecting line respectively. The first cooling pipe is connected with the back-pressure feedback component through the fifth connecting line. The second cooling pipe is connected with the automatic back-pressure tracking pump through the fourth connecting line. The back-pressure automatictracking pump and the back-pressure feedback component are connected with the control display system through a communication line and a flat cable.
