二氧化氯与酸液协同解堵施工 ,可解除铁硫化物、细菌群落、高聚物及无机盐类垢物对地层造成的堵塞。中原油田采油六厂应用该工艺技术对 6口注水井实施解堵后 ,降压增注和增油效果明显 ,平均单井降低注水压力 10MPa ,平均单井日增注水 40m3 ,对应油井平均单井日增油 6.8t ,相应的经济效益为 10 63 .9万元。
Chlorine dioxide and acid solution in conjunction with the anti-blocking construction, can relieve the formation of iron sulfide, bacterial communities, polymers and inorganic salts of scale blockage caused by the formation. Zhongyuan Oilfield Sixth Production Plant applied this process technology to the 6 injection wells after the implementation of anti-plugging, injection pressure relief and oil increase significantly, the average single well to reduce water pressure 10MPa, the average single well daily injection of water 40m3, corresponding to the average single well wells Increasing oil 6.8t, the corresponding economic benefits of 10 63.9 thousand yuan.
