Abstract
An X-ray-based test device for a plugging removal effect of a sulfur dissolvent on a sulfur deposition rock sample includes a constant speed and pressure pump, a first intermediate container, a second intermediate container, a first pressure transmitter, a core holder, a second pressure transmitter, a first electric pump, a third intermediate container, a back-pressure valve, a gas flow meter, an H2S neutralization tank, a second electric pump, a back-pressure transmitter, a confining pressure transmitter, an X-ray generator, an X-ray detector and a thermotank. A sour gas sample is placed in the first intermediate container, and nitrogen is filled in the second intermediate container. The sulfur dissolvent is placed into the third intermediate container. A confining pressure inlet is formed in the core holder. The test device may be used for evaluating the plugging removal effect of the sulfur dissolvent injected into the sulfur deposition rock sample.
