Research on a kind of hydropower spray solution plugging technology and its application

When the oilfield enters the development mid, because the water injection caused by many factors such as oil Wells reservoir of perforating boreholes and near wellbore pore jams, bring about oil well drop channel produce, well water quantity decreased, greatly influenced oilfield development level. Aiming at these problems, this paper introduces a kind of hydropower spray solution plugging technology, this technology is the use of underground controllable speed rotating self-vibration cavitation jet solution plugging device, produce the high pressure water jet directly flush borehole wall and high frequency oscillation solutions hydraulic wave, hot air noise wave content, for understanding YouQiLiu or water plugging provide a clean fluid channels, to increase the purpose of increasing note. We in jilin oilfield scaling worst-hit area chose 12 Wells was conducted through late tracking evaluation, test effect is very apparent. For jilin oilfield stimulation measures provides a new way.
