When the scale deposit is serious, water proof oil recovery packer sits and seals the difficulty, and some wells are died because of the scale deposit is stifled, and the sucker rod is broken, and the oil well is forced to shut down. Therefore, the problem of scaling has become one of the problems that cannot be ignored, and to solve the problem of scaling of an oil well, it is necessary to know the amount of scaling of the oil well.
