摘要
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。
The technique of plug removal by combination of chlorine dioxide and acid solution can be used to remove the formation damage caused by iron sulfide, bacterial colonies, high polymer and inorganic salt scale. In No.6 Production Company of Zhongyuan Oil Field, this technique was applied to the damage removal of 6 injection wells, obviously resulting in water injection and oil production increase by pressure decreasing. Consequently, on an average, single well injection pressure dropped by 10MPa; daily single well water injection increased by 40m 3; daily single well oil production of corresponding oil wells increased by 6.8t, respectively; and the relevant economic benefit equals to RMB 10.639MM Yuan?
