油水井的长期生产和注水势必会受到来自外部和内部各种因素的影响,堵塞问题是造成产油能力下降或注水困难的主要原因,但随着油田开发,注入水水质较差,各种增产措施使得地层污染类型复杂化,因此尝试了二氧化氯解堵技术,利用HRS解堵剂与酸协同实现解堵,并取得明显效果。 The long-term production and water injection of oil and water wells are bound to be affected by various factors from the outside and the interior. The blockage problem is the main reason for the decline in oil production capacity or water injection. However, with the development of oilfields, poor water quality, Because of the complicacy of formation pollution types, we tried the technology of chlorine dioxide plugging, and achieved the obvious effect by using HRS plugging agent and acid to achieve the plugging-off.
