The invention discloses a high-temperature and high-pressure
sulfur deposition microscopic seepage
visualization experiment device and method. The device is composed of an injection
system, a high-temperature and high-pressure visual kettle (14), a pressure supply
system, a
data acquisition and analysis
system, a fluid
recovery system and an injection
branch pipe; the injection system comprises an ISCo micro-
injection pump (1), an intermediate container, a constant-temperature heating box (6) and a pressure gauge (3), the intermediate container is arranged in the constant-temperature heating box (6), and the ISCo micro-
injection pump (1) is connected with the intermediate container; the
data acquisition and analysis system comprises a
microscope (13), a high-brightness
light source and a computer (26); the pressure supply system comprises an annular pressure tracking pump (28), a
back pressure pump (28), a
back pressure valve (18) and a pressure gauge (17); and the fluid
recovery system comprises a wide-mouth
bottle (21) with a rubber plug, a balance (22), a flowmeter (23) and a
tail gas absorption tank (24). With the high-temperature and high-pressure
sulfur deposition microscopic seepage
visualization experiment device and method of the invention adopted, the problem that the
microscopic morphology and the deposition amount of
sulfur at the
throat of arock core cannot be observed in real time in the previous
sulfur deposition microscopic seepage experiment is solved.
