   We strictly implement the requirements of ISO9001 and API quality management system to ensure that our products and services meet customers’ requirements. At the same time, we can manufacture downhole operation tool according to customers’ requirements. Today, our customers work all over the oil fields in China.

   Now, we are sincerely willing to cooperate with you and provide you with more choices.

Retrievable Bridge Plug

   Retrievable bridge plug is a downhole plugging tool used in oilfields, which consists of setting mechanism, anchoring mechanism and sealing mechanism etc. With unique self-locking structure and reliable two-way pressure bearing capacity, it can ensure reliable sealing without the need to use an overlying mortar surface. The retrievable bridge plug is set by cable setting tools or hydraulic setting tools. When necessary, it can be released and recovered. After wearing parts are changed, it can be still re-utilized downhole. The retrievable bridge plug can be used in cooperation with downhole tools for temporary plugging and selective plugging etc. It can be extensively used in production test, workover, testing and hydrocarbon reservoir improvement etc., and is a safe, reliable and cost effective full-function downhole plugging tool.

   Advantage Reliable anti-sticking design: the slips use a built-in slip structure, so that the bridge plug is not easily blocked and stuck when pulled and lowered in the well bore and can be used safely in the well of any obliquity.
Flexible setting mode: the bridge plug can be sent in well and set by the cable setting tool or the hydraulic setting tool, and it is only required to select corresponding setting tool based on specific well conditions.

   Unique anchoring mechanism: by flexibly combining the slips, slip cone and the outer barrel of the slips, the bridge plug has good two-way pressure bearing capacity and is applicable to the casing of various grades.

Notice:
Casing of setting section should be without serious corrosion, breakage or serious deformation.
Drift and scrape the well bore, and wash out the dirt and dead oil before RIH.
Control the RIH velocity in 30 tubings/hour.
Control the blockage force within 30 KN during RIH.

   Run the releasing tool to 3-5 meters from the bridge plug surface, then clean the well completely.

   To prevent falling into the well during POOH, avoid revolving of the pipe string.
Retrievable Bridge Plug for Cement Squeezing Retrievable bridge plug for cement squeezing is a downhole cement squeezing and plugging tool used in oilfields. It consists mostly of setting mechanism, anchoring mechanism, sealing mechanism, and sliding sleeve switching mechanism, etc. The retrievable bridge plug for cement squeezing is set by cable setting tools or hydraulic setting tools. After cement squeezing, it can be released and recovered. After wearing parts are changed, it can be still reutilized downhole.

Notice:
The cautions of RIH, Setting and POOH: please refer to the retrievable bridge plug. After completing cement squeezing operation, lift the pipe string by 2-3 meters and reverse well cleanout for over a cycle till fresh water passes in and out with large displacement.

During transport and handling, avoid colliding and getting wet.

Store away from heat, not allow to contact acid, alkali and salt, etc.
