摘要
随着油田开发时间的延长,地层压力也不断下降,特别是边缘区块的注水系统跟不上开发要求,使低产井(5t/d 左右)越来越多。据1990年统计,中原油田共有低产井300多口。这些油井的总产液量偏低,液流从井底带出的热焓也偏低,使已建的单管密闭不加热集输系统在冬季不能正常生产。为此,于1991年冬季将工频电解堵技术用于低产井集输系统,并取得了满意结果。
In according with the single pipe,non-heating transferring stripper wells and utilizing the theory of thermal equilibrium the author shows the boundary conditions.Combining the technique of electricopening up blocks used in winter season the author talks about his experience.
