It is usedoil, gas, or water well with normal conditions, or usedwell with casing deformation, jetting or paraffin deposit. It’s used to take place of sand fillingcement plugging.

During working, no mechanical movement is neededsealingreleasing. So it has advantages to be usedhorizontaldeflecting well. It is widely used for water injection, acidification, plugging, fracturingother constructions.

Cup packer can be used for oil extraction, mechanical pluggingother constructions.

Double sealing is mainly used for oil extraction, mechanical pluggingother constructions.

K344 short barrel packer can be usedwater injection, fracturingother operations.

It’s a mechanical slip packer which is mainly used for oil extraction by layer, mechanical pluggingother constructions.

It has the long-term effect of anti-scale, prevent scalesoluble scale.

Rotational sand processor is mainly used for pumping well with high sand content.

It’s mainly usedoil well for sand control. Installed under the oil-well pump to filter the fluid entering pump. It can be usedall kinds of oil-gas well, water well, vertical well, sidetracked hole, horizontal wellsteam flooding wellland or at sea.

This is a mechanical slip packer, which is usedmany different constructions, such as oil extraction by layer, water injection, water exploration, plugging, squeezing, acidification, fracturingso on.
