为提高胜利油田油井解堵成功率及油井产量,进行了声波配合混气水解堵的理论研究。声波配合混气水解堵工艺以混气水作为激发流体即能大幅度提高声波的振动幅度,又能通过降低空化阈以更好的发挥其空化作用,可以达到解除地层堵塞、疏通液流通道、改善油层内部流体的渗流条件、增加油水井产能的目的,而且可以将堵塞物有效携带出井筒,较之单纯混气排液工艺适用面更广,有效解堵时间更长。
In order to improve the success rate of wells and the oil well production in Shengli Oilfield, the theoretical study of acoustic mixing and gas-mixing hydrolysis was carried out. Acoustic wave mixed with gas hydrolysis plugging process to mixed gas as the excitation fluid that can significantly increase the vibration amplitude of sound waves, but also by reducing the cavitation threshold to better play its role in cavitation can be achieved to lift the formation blockage, to clear the liquid flow Road, to improve the fluid flow conditions within the reservoir to increase the production capacity of oil and water wells, and can block the effective carrying out of the wellbore, compared with simple mixed gas drainage process is more applicable to the surface, the effective block-off time longer.
