Description
Technical Field
The invention belongs to the technical field of surface chemistry and high polymer materials, and particularly relates to a foaming agent composition.
Background
Oil recovery can be divided into three distinct stages. The first stage is primary recovery, in which the natural fluid pressure and rock expansion of the reservoir push the crude oil toward the well. Such a kind ofThe method can recover 30% of crude oil. The next stage is secondary oil recovery. In this method, oil is transferred to a production well using water flooding or pressurized non-miscible gas injection techniques, thereby enhancing oil recovery. However, complex geologic formations remain a challenge for the production of reservoir residual oil. To address this problem, foam has been introduced as a miscible fluid in applications to enhance reservoir recovery. Foam has shown great potential in improving surface wave and efficiency and vertical wave and efficiency, thereby significantly improving the recovery efficiency of hydrocarbon reservoirs. The foam is formed by different surfactants and gas phase (air, N 2 Or CO 2 ) Two-phase systems (i.e., flow bubbles and trapped bubbles) are formed. Physically, flowing bubbles cause flow resistance, and trapped bubbles block some flow channels, reducing the relative permeability of the gas. In addition, foam can significantly improve wash efficiency by reducing residual oil saturation, i.e., IFT to ultra-low values, using surfactants to reduce water-oil interfacial tension (IFT). A number of experimental measurements indicate that the presence of oil has an adverse effect on the propagation kinetics of the foam in the porous medium. After the foam enters larger pores and throats in the porous medium, the flow resistance is increased due to the Jamin effect, and then the foam turns to gradually enter smaller pores and throats, so that the oil saturation is higher, and the recovery ratio is improved.
The basic principle of the foam flooding technology is that a certain amount of foaming agent and foam stabilizer are added into injected water, and the injected fluid forms foam in underground pores through gas-liquid co-injection, so that the viscosity of the injected fluid is improved, gas streaming in the stratum is prevented, and powerful foam flakes are generated in a high-permeability area to improve the sweep efficiency of a heterogeneous reservoir. However, the use of foam in porous media also faces challenges such as thermal and mechanical stability of the foam, optimal surfactant concentration to achieve maximum stability, interaction mechanism of the foam-oil interface, in situ generation and expansion of the foam. There are three interdependent conditions for foam destabilization: (1) Foam drainage, under the action of gravity, liquid is separated from the surface of the bubbles, and the surface of the bubbles is blocked by capillary force and shearing stress; (2) liquid film rupture; (3) Gas diffusion between bubbles caused by uneven size distribution of bubbles. The above problems can be improved by increasing the amount of the foaming agent, but the cost is increased, and the conventional ionic surfactant is greatly influenced by divalent ions in the formation water, which is mainly represented by compression of a double-electrode layer of the molecule, so that the dispersion of the surfactant is poor, and the interfacial activity is reduced. Foam properties can be enhanced by adding foam stabilizers (or adjuvants) in addition to foaming agents, which are commonly done by adding polymers to increase the viscosity of the aqueous phase, and by viscous forces to slow the liquid release rate. The network of polymer stretched in solvent water can increase the strength of the liquid film and improve the foam stability. However, common Polyacrylamide (PAM) polymers have the defects of excessively large molecular weight, weak hydration capacity and weak shearing resistance, and can not better solve the problem of premature destabilization of foam.

The test examples mentioned in the present invention are all composed of 82000ppm NaCl and 1500ppm CaCl 2 And a foaming agent composition solution having a mass concentration of 0.4wt% of a simulated water formulation having a mineralization of 85000ppm composed of 1500ppm MgCl2 produced a foam after stirring for 60s at 3000rad/min using a Waring stirrer.
Test example 1 (foam comprehensive Property)
Referring to FIG. 1, FIG. 1 shows the foam volume and foam liquid half-life produced after stirring for 60 seconds at 3000rad/min using a Waring stirrer for examples 1-4 with an effective content of 0.4wt% and comparative examples 1-4 with an effective content of 0.4wt% in a saline solution configuration. It can be seen that the half-lives of the foam of comparative example 1, comparative example 3 and comparative example 4 are all below 5h, while the half-lives of the foam of comparative example 2 containing the hotplate glue and the foam of examples 1-4 are all above 10h, and the half-lives of the foam of examples 1-4 provided by the invention are all above 15h. The foams prepared in example 3 all had the longest foam-to-liquid half-life (20 h) and the foams prepared in example 4 all had the largest foam initial volume (520 mL). The above performance comparison fully demonstrates the excellent performance of the blowing agent compositions provided by the present invention.
Test example 2 (foam microcosmic appearance)
Referring to FIG. 2, FIG. 2 shows the foam particle size change, foam liquid film thickness and foam decay process (0 hours, 2 hours and 6 hours after foaming, shown in sequence from left to right) of the foam produced by stirring the test examples 1-4 and comparative examples 1-4 with a Waring stirrer at 3000rad/min for 60s at 0-6 hours with an effective content of 0.4wt% are listed and compared. The foams of examples 1-4 were drained slower, foam film thickness stabilized and bubbles coalesced slowly over 0-6 hours as compared to the foams of comparative examples 1-4 which were drained faster, foam film thickness decreased and foam particle size increased due to coalescence. The above performance comparison fully shows that the foaming agent composition provided by the invention has stronger water-retaining property.

Wherein the lathering volume is reduced from 400mL in the unaged state to 195mL after 33 days of aging, the lathering performance is greatly lost, and the lathering half-life is reduced from the initial 3 hours to 0.6 hours.
FIG. 7 shows the change in foam properties with aging time at 120℃for a solution of the foaming agent composition of comparative example 3 having an effective content of 0.4% by weight.
