Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing.

[0023] figure 1 A device 10 for monitoring phase state changes of a fluid in a porous medium according to the present invention is schematically shown. Such as figure 1 As shown, the device 10 includes a generally dumbbell-shaped body 1 . The body 1 includes sealed chambers 2 distributed along the axial direction, which are used to accommodate porous media 3 . The porous medium 3 is, for example, a cylindrical core sample. The porous media 3 described below all take rock core samples as examples, but it does not mean that only rock core samples are required to be protected, which is just for convenience of description.

[0024] According to the present invention, the body 1 further includes an annular cavity 4 surrounding the sealed cavity 2 , and a flexible cylinder 5 arranged between the sealed cavity 2 and the annular cavity 4 . The flexible cartridge 5 is preferabl...

Abstract

The present invention relates to an apparatus for monitoring fluid phase behavior changes in a porous medium, the apparatus comprises a body comprising a sealed chamber for accommodating the porous medium, an injection assembly, and an end cover, wherein the injection assembly is used for adding a fluid to be measured into the sealed chamber, and can adjust the pressure of the fluid to be measured in the sealed chamber, the end cover is in sealed connection with both ends or any end of the body, and the end cap is provided with a perspective window for monitoring the phase behavior changes of the fluid to be measured in the sealed chamber. By use of the apparatus for monitoring the fluid phase behavior changes in the porous medium, influence of the porous medium to the fluid phase behavior changes may not be ignored during the study on phase behavior changes of a hydrocarbon fluid.

Description

technical field [0001] The invention relates to the technical field of oil and gas field exploration and development, in particular to a device for monitoring fluid phase changes in porous media. Background technique [0002] In the field of oil and gas field exploration and development technology, it is very important to study the phase state change of hydrocarbon fluid in porous media for gas flooding to enhance oil recovery. [0003] At present, a relatively complete theory and method have been formed for the study of the phase state change of hydrocarbon fluids. However, the data for studying the phase state change of hydrocarbon fluids usually come from multiple sets of PVT (fluid pressure, volume and temperature test) experiments under different pressures. This kind of PVT experiment is carried out under the condition of ignoring the influence of porous media on the change of fluid phase state. Therefore, it can only conduct in-depth research on the physical parameter...
