Eccentric Water Distributor
It can be used together with packer, bottom ball seat, plug and screen to inject water in high pressure.
Checak Valve with Pump Outlet
It’s installed on the injection pump wellhead. It’s a device that filtering mechanical impurity, such as oil contamination and suspended solids in the injection water.
Check Valve for Water Well
It’s installed on the injection pump wellhead. It’s a device that filtering mechanical impurity, such as oil contamination and suspended solids in the injection water.
Hydraulic Release
It is used for fracturing, acidification, testing string and other constructions.
After improvement, use hydraulic release instead of release by unscrewing. It solved the problem that unscrewing is not allowed after well completion or because of other reasons. It is widely used in a variety of production process in the string.
Safety Joint
It is used for fracturing by layer, acidification by layer, testing string and other constructions.
Hydraulic Anchor
It’s used to anchor oil pipe. The ID of casing isΦ118～Φ12 and the temperature≤125℃.
Retrievable Cement Squeezing Bridge Plug
It’s a kind of downhole tool used in oil field for plugging and squeezing. It is mainly composed of a setting unit, anchoring unit，the sealing unit and sliding sleeve switch. Retrievable bridge plug is delivered to suitable place by hydraulic tools or cable to realize sealing, can be retrievable after unsealing. It can be reused after replacing wearing parts.
Air Sealing Packer
Sealingtesting mainly for sitespecific buckle threaded OCTG connections and ground pipelines, into the wells and sealed prior to use for testing an experimental technique is to ensure that gas production tubing string and sealing ground pipelines key means. At present, the technology has become high-risk, high-sensitivity, particularly thoseoilfieldcontaining H2S supporting the development of technical standards for the construction field.
Hydraulic Expansion External Casing Packer
It is a important well completion tool. It’s mainly used in complex oil, gas or water well completion engineering to realize downhole packing or plugging, improve well cementation and well completion.
It is used for staged packing of open holes for further operation. The pressure opens the packer’s rubber for setting. It mainly consists of central pipe, rubber, open/close valve. The open valve is activated by enough pressure to demanding value, and then set the packer. More pressure shall activate the close valve to close the packer.
