specific example

[0059] To give a specific example, step 2 can be implemented as:

[0060] Inject water to H 1 Height, continue to inflate and continuously adjust the air pressure, observe the critical condition of the air-supported water piston migration in the sand column to the sudden bubble, and record the water column height H at this time 1 =6.5m, air pressure size P 1 =0.07MPa, critical sand particle size Φ 1 =0.075mm;

[0061] Inject water to H 2 Height, continue to inflate and continuously adjust the air pressure, observe the critical condition of the air-supported water piston migration in the sand column to the sudden bubble, and record the water column height H at this time 2 =13.8m, air pressure size P 2 =0.15MPa, critical sand particle size Φ 2 =0.125mm;

[0062] Inject water to H 3 Height, continue to inflate and continuously adjust the air pressure, observe the critical condition of the air-supported water piston migration in the sand column to the sudden bubble, and re...

Abstract

The invention discloses a simulation experiment device and method for determining the distribution range of a continuous tight sandstone gas reservoir. The device comprises a tight sandstone reservoir layer unit, a gas inflation and pressure measurement unit and a formation water simulation unit, wherein the tight sandstone reservoir layer unit comprises a cylindrical quartz glass tube 2 and eight sand layers 1 of different particle sizes installed in the cylindrical quartz glass tube 2; the gas inflation and pressure measurement unit is used for simulating gas filling and comprises a gas inflation steel tube 3, a methane gas bottle 4 and a pressure gage 5, the two ends of the gas inflation steel tube 3 are connected with a simulation throat 7 at the bottom of the cylindrical quartz glass tube 2 and the methane gas bottle 4, and the pressure gage 5 is installed at the bottle mouth of the methane gas bottle 4; the formation water simulation unit is used for simulating different hydrostatic pressure, and comprises a water tube 6 connected to the upper portion of the cylindrical quartz glass tube 2. By the adoption of the simulation experiment device and method for determining the distribution range of the continuous tight sandstone gas reservoir, the distribution range of the continuous tight sandstone gas reservoir can be effectively determined, and the formation simulation experiment of the continuous tight sandstone gas reservoir is perfected.

Description

technical field [0001] The invention relates to the technical field of petroleum and natural gas geology, in particular to a physical simulation experiment device for determining the distribution range of continuous tight sandstone gas reservoirs, and a method for determining the distribution range of continuous tight sandstone gas reservoirs using the physical simulation experiment device. Background technique [0002] Tight sandstone gas reserves are huge worldwide. At present, in the United States and China, the reserves and production of tight sandstone gas exceed one-third of the total reserves and production of natural gas, which will be an important way to solve the energy shortage. Continuous tight sandstone gas is the main form of tight sandstone gas. There are different opinions on the accumulation mechanism of this type of gas reservoir, and no universal mechanism explanation has been given, which makes it impossible to determine its distribution range now. From ...
