Problems solved by technology
The previous water-rock experimental devices did not consider the addition of open fluid and saturated gas fluid. For example, the patent application number CN201710192524.9 provides an open high-pressure reactor with wide-range pressure regulation and its working method, and the reaction is adjusted through the accumulator. The internal pressure of the kettle, the fluid is added into the reactor through the high-pressure air pump and the reaction product is discharged, but the open process of adding and flowing out of the equipment cannot be carried out continuously in the long-term water-rock reaction process, and cannot satisfy the constant open fluid Requirements for simulation experiments of gas-water-rock reaction under certain conditions

Embodiment Construction
[0029] The present invention will be further described below with reference to the accompanying drawings.
[0030] figure 1 A gas-water-rock reaction device according to an embodiment of the present invention is shown, including a gas-liquid supply unit, a reaction unit and a discharge unit. The gas-liquid supply unit is used to provide a gas-saturated solution that meets the temperature and pressure required for the experiment. The reaction unit is used to receive the gas-saturated solution flowing in at a constant rate from the gas-liquid supply unit, and to act on the rock powder with the gas-saturated solution. The discharge unit is used to discharge the reacted fluid sample.
[0031] The reaction device ensures that the gas-saturated solution reaches the temperature and pressure conditions required for the experiment before entering the reaction unit, can truly simulate the formation conditions, is easy to operate, has strong sustainability, and can improve and ensure t...

Description
technical field [0001] The invention relates to the technical field of oil and gas exploration, in particular to a gas-water-rock reaction device and method. Background technique [0002] The experimental study of gas-water-rock interaction is one of the necessary research methods to simulate the variation law of formation conditions. The previous water-rock experimental devices did not consider the addition of open fluid and saturated gas fluid, such as patent application number CN201710192524.9, which provides an open high-pressure reactor with wide-range pressure regulation and a working method, and the reaction is regulated by an accumulator. The pressure in the kettle, the fluid is added into the reaction kettle through the high-pressure air pump and the reaction products are discharged, but this open process of adding-outflow of the equipment cannot be carried out continuously in the long-term water-rock reaction process, and can not meet the constant open fluid Requi...
