Problems solved by technology
[0003] There is a hyperbaric chamber-type formation pressure simulation method and device in China. Due to the large size of the device, complicated operating procedures, and the limitation of the laboratory space and the model body, it is not suitable for the existing multi-functional thermal recovery three-dimensional physical model device.
However, the existing 3D physical model reservoir pressure simulation system has few monitoring points and cannot realize online monitoring and real-time tracking of the overall pressure field

The invention provides a multifunctional thermal recovery three-dimensional physical simulated reservoir pressure system. The system comprises a model body, a pressure sensor, a computer, an adjustment controller and an electromagnetic valve, wherein the pressure sensor is connected to the model body to monitor the change of simulated reservoir pressure in the model body and transmit an acquired pressure value to the adjustment controller, the adjustment controller is connected to the model body, the electromagnetic valve and the computer and transmits the acquired pressure value to the computer, the computer controls on-off of the electromagnetic valve according to the acquired pressure value, and the electromagnetic valve is connected to a production well in the model body and serves as a control switch of an output system of the production well. By the adoption of the system, the safety coefficient of experiments is increased, an experiment condition is closer to a real simulated reservoir pressure change condition, and experimenters can make judgment and take measures in time when pressure becomes abnormal.
Description
technical field [0001] The invention relates to an indoor physical simulation test device for petroleum thermal recovery technology, in particular to a multifunctional thermal recovery three-dimensional physical simulation oil reservoir pressure system. Background technique [0002] Multifunctional thermal recovery three-dimensional physical model device, with a pressure resistance of 8Mpa and a temperature resistance of 350°C, can simulate different linkage combinations of vertical wells / horizontal wells such as steam flooding, steam huff and puff, steam foam flooding, chemical steam flooding, steam composite gas flooding, etc. The physical simulation of the development method can not only realize the research on the oil displacement mechanism of various new technologies, but also realize the similar simulation of real oil reservoirs. Using different well pattern layouts (which can simulate multi-well pattern layouts such as vertical well nine points, double horizontal well...
