PACKER

◆ Y341 PACKER
Uses:
Y341 series packer is mainly used for water wells and injection wells layered layered with oil.
How it works:the tool down to the design depth, the injection of liquid within the tubing, when the pressure reaches 8-10MPa, the compression piston packer rubber tube, rubber tube to the radial swell, thereby sealing the oil casing annular space. As the packer has a one-way locking device, and therefore pressure relief, the packer will not be reopened itself to the oil casing into the annular space within the liquid, when the hydraulic pressure of 1MPa, the flushing piston is opened, continue Note the liquid, you can achieve flushing operations, put up the column can be re-opened the packer.

◆ Y441 PACKER
Uses:
Y441 series packer anchor with two-way function, it is widely used in the stratification test oil, oil, looking for water, cards plugging and other processes. Especially for large inclination, conventional packer packer's not easy to process.
How it works:packer location next to the design, add hydraulic tubing to 15-16MPa, regulators 5min, the packer packer. After the experience relief from the casing seal, to confirm the reliability of packer. Such as single-stage using the packer, re-opened when the first mention on the column slowly, observe changes in weight indicator, when the load exceeds the original string hanging heavy 70-80KN not lifted, it will be put back beyond the original column 10KN string hanging heavy around, then put on the string until it is completely lifted up, such as multi-use, re-opened with reference to a single-stage method reopened method.
