Embodiment Construction

[0029] The present invention will be further described below in conjunction with accompanying drawing.

[0030] figure 1 An apparatus 100 for simulating water-rock reactions in a closed system according to an embodiment of the present invention is shown. like figure 1 As shown, the device 100 includes a pressure-resistant container 1 , a gas pressurization component 2 and a collection component 3 . Among them, the pressure-resistant container 1 is used for storing samples and as a vessel for water-rock reaction. The gas pressurizing assembly 2 is used to communicate with the pressure-resistant container 1 to deliver gas into the pressure-resistant container 1 so as to obtain a closed reaction environment in the pressure-resistant container 1 . The collection component 3 is used to collect information in the pressure vessel 1 to monitor the progress of the water-rock reaction and the test data of the water-rock reaction in real time.

[0031] Thus, after putting the sample ...

Abstract

The invention provides a device for simulating closed system water-rock interaction. The device comprises a pressure container used for containing samples, a gas pressurization component communicated with the pressure container, and a collecting component used for collecting information in the pressure container. The device can properly simulate stratum environment, and ensures that data can be monitored in real time.

Description

technical field [0001] The invention relates to the technical field of petroleum geological reservoir research, in particular to a device for simulating water-rock reaction in a closed system. Background technique [0002] Carbonate rocks are highly sensitive to diagenesis, and the secondary pores and caves formed by dissolution of carbonate rocks on the surface and during burial are important oil and gas storage spaces. Fluid-rock interactions in deep hydrocarbon-bearing carbonate reservoirs have received considerable attention. However, it is still necessary to strengthen understanding through simulation experiments on how the fluid-rock in the deep burial environment interacts, as well as the material changes and energy changes that occur during the interaction. [0003] The existing water-rock chemical interaction devices mainly focus on simulating the water-rock reaction in the flow process. The length of such a simulation process is limited, usually several hours, and...
