Abstract
Petroleum is the country’s strategic energy and plays a pivotal role in the development of the national economy. With the in-depth development of oil fields, the problem of shortage of oil resources will become increasingly prominent. Water injection development has a better effect on maintaining formation pressure and oil displacement. Air foam flooding technology can not only form formation pressure, but also avoid water channeling and gas channeling problems, thereby improving oil recovery. In this paper, a foam scanner is used to evaluate the foaming performance of the foaming agent, and to screen the air foam system. According to the performance evaluation of the foaming agent, it is recommended that the on-site water injection station use 0.4~0.6%P + 0.05~0.075%W (the ratio of foam to stabilizer P/The W concentration is 8) Strengthen the foam system formula. The foaming agent’s temperature resistance, stability, salt resistance, adsorption resistance, oil resistance, emulsification and foam regeneration ability were evaluated. It has certain guiding significance for the mine field test.
