随着油田开发的时间延长,各种因素导致了油水井完井后出现固井质量不合格,表现在一、二界面固结质量差以及管外窜槽等,完井后难以正常投入到生产当中,就需要二次固井。针对完井的质量不合格,严重影响油井的正常生产,文章开展了对油水井二次固井封窜的研究。 With the prolongation of oilfield development, various factors have led to the failure of cementing quality after completion of oil and water well, such as poor solidification quality at one or two interfaces and channeling outside the pipe. After completion, it is difficult to properly put into production Among them, you need the second cementing. In view of the unqualified quality of well completion, which seriously affects the normal production of oil well, the paper carried out research on secondary cementing and channeling of oil and water well.
