Problems solved by technology

[0004] In order to solve the problem that the existing foaming performance measurement method cannot measure the foaming agent in CO 2 The problem of foaming performance in gas, the present invention provides a kind of measurement foaming agent in CO 2 The device for foaming performance in gas and its measurement method, its measurement results can be compared with the foaming performance in air measured by international standards (ISO696-1975) and national standards (GB / T7462-94). Experimental data comparing blowing agents in CO 2 The foaming performance in the middle is more intuitive and the results are more accurate

Embodiment 1

[0043] Embodiment 1 whipping agent is 2000mg / L petroleum sulfonate aqueous solution

[0044] Prepare 1000mL of 2000mg / L petroleum sulfonate aqueous solution as the test solution (i.e. the foaming agent to be tested for the test), and carry out the following steps:

[0045] 1) connecting device;

[0046] Use rubber water pipes to connect the outlet pipe and return pipe of the constant temperature water bath to the water inlet pipe and outlet pipe of the jacket measuring cylinder 3 respectively, and adjust the temperature of the constant temperature water bath to 50°C; In an isothermal water bath, make the temperature reach the water bath temperature, and set aside;

[0047] Install the metering tube combination structure 2 on the lower end of the separating funnel 1, and keep the metering tube combination structure 2 and the separating funnel 1 perpendicular to the horizontal plane;

[0048] Put the sealing rubber plug 4 on the mouth of the jacket measuring cylinder 3, insert...

Embodiment 2

[0056] Embodiment 2 whipping agent is 3000mg / L petroleum sulfonate aqueous solution

[0057] Prepare 1000 mL of 3000 mg / L petroleum sulfonate aqueous solution as a test solution, and repeat steps 1) to 3) of Example 1.

[0058] The foaming height measured in this embodiment is 340mL, and the half-life is 1120s.

Abstract

The invention discloses a device for determination of foaming performance of a foaming agent in CO2 in an oil field and a determination method thereof. The device comprises a separating funnel (1), a metering tube composite structure (2), a jacketed measuring cylinder (3), a sealing rubber plug (4), a breather tube (5) and a one-way valve (6); the metering tube composite structure (2) is mounted at the lower end of the separating funnel (1); the sealing rubber plug (4) is plugged into a mouth part of the jacketed measuring cylinder (3); the sealing rubber plug (4) is provided with a metering tube hole (42), a breather tube hole (41) and a one-way valve hole (43) for respectively inserting the metering tube composite structure (2), the breather tube (5) and the one-way valve (6). The determination method comprises the steps: 1) connecting the device, and filling a test solution; 2) filling the device with CO2; and 3) determining the foaming performance. According to the device provided by the invention, the determination method is rapid, efficient and easy to carry out; and compared with the foaming performance in air measured by international standards and national standards, an obtained determined result is more intuitive and accurate.

Description

technical field [0001] The present invention relates to a foaming agent performance measuring device in the field of petroleum development and a measuring method thereof. Specifically, the present invention relates to a method for measuring the CO 2 Apparatus for medium foaming performance and method for its determination. Background technique [0002] CO 2 Foam is a non-Newtonian, pseudoplastic fluid with high flow resistance in the porous media of reservoirs. It is widely used in oil displacement, profile control, channel sealing, etc. in oil field development at home and abroad. Since the foaming performance of the blowing agent directly affects the CO 2 The application effect of the foam, so the determination of the blowing agent in CO 2 The foaming performance in the film is very important. Existing methods for measuring the foaming performance of blowing agents include: Ross-Miles method, Waring-Blender method, DIN hole plate impact method, API method, compressed a...
