Embodiment 1
[0054] like figure 1 Shown: A device for measuring the migration of carbon dioxide in carbon dioxide flooding and storage, including an injection system, a sealing chamber clamping system and an information collection system. The sealing chamber clamping system is filled with sand, crude oil and formation water simulation Formation conditions, an injection well 10 and a production well 11 communicating with the bottom of the formation are arranged above it; the injection system is connected to the sealing chamber support system and a certain amount of carbon dioxide is injected through the injection well 10, and the production well 11 is used for The crude oil is discharged to the outside; the information collection system includes a gas detector 17 and an information data processing computer 16, and the gas detector 17 is evenly distributed in the internal space of the sealing box clamping system, and the gas detector 17 and the information data processing computer 16 signal ...
Embodiment 2
[0061] A method for using the device for measuring the migration law of carbon dioxide in the above-mentioned carbon dioxide flooding and storage, comprising the following steps:
[0062] Step 1, adding specific mesh sand into the sealed cavity holder 12;
[0063] Step 2, using a saturation system to saturate the clamping system of the sealed chamber with formation water, crude oil, and air;
[0064]Step 3, using an injection system to inject a certain amount of carbon dioxide from the injection well 10;
[0065] Step 4, record the variation of water production, oil production and gas production at different times through the recovery metering system;
[0066] Step 5, ascertain and count the migration law of carbon dioxide through the information collection system;
[0067] Step 6, when the carbon dioxide reaches the leakage level, the surfactant solution is injected into the injection well 10 through the injection system to block the carbon dioxide.
[0068] In step 1, acc...
Embodiment 3
[0081] like Figure 9 , Figure 10 Shown:
[0082] A data processing method for measuring carbon dioxide migration laws in the above-mentioned carbon dioxide flooding and storage: comprising the following steps:
[0083] 1) Output the data of the concentration of carbon dioxide measured by the gas detector 17 changing with time.
[0084] 2) Determine the three-dimensional coordinates of the gas detector 17 and the three-dimensional coordinates of the injection well 10 and the production well.
[0085] 3) Obtain the carbon dioxide concentration data of each gas detector 17 in the sealed chamber system at a certain time t0.
[0086] 4) By using the three-dimensional coordinates of the gas detector 17 and using the depth of the color to represent the size of the concentration data, a three-dimensional carbon dioxide concentration field map in the sealing ring system at a certain moment can be obtained.
[0087] 5) Establish a three-dimensional carbon dioxide concentration fie...
