BOP Stack

A BOP stack can well function in different environments of low or high temperatures or rich in sulphur. The blowout preventer assembly can meet diverse well control demands in processes of drilling, well testing and underground drilling. Our BOP stack ranges from 2 9/16" to 30" in its nominal diameter and from 3.5MPa (500psi) to 140MPa (20000psi) in the working pressure. The stack adopts a forged or cast body and can be closed manually or hydraulically.

1. Annular BOP (with Spherical Rubber)
3. An annular BOP with spherical rubber is a type of blowout preventer for oil and gas drilling as well as mining and other industries. The BOP works mainly to stop any liquid from surfacing in a dangerous explosion to create a safe working environment.
1. Ram BOP (with Cast Structure)
3. A ram BOP with cast structure is a type of blowout preventer for oil and gas drilling, mining and other industries. The BOP works mainly to stop any liquid from surfacing in a dangerous explosion to create a safe working environment.
1. Ram BOP (with Forged Structure)
3. A ram BOP with forged structure is a type of blowout preventer for oil and gas drilling, mining and other industries. The BOP works mainly to stop any liquid from surfacing in a dangerous explosion to create a safe working environment.
1. Rotary BOP
3. A rotary BOP is a well control device usually applied in underbalanced drilling wells. The rotary blowout preventer is made up of the body, the clamping cylinder assembly, the rotating assembly and the drilling rod driver assembly.
1. Coiled Tubing BOP
3. The tubing BOP is often used to control the wellbore pressure in drilling processes like well testing and repairing, in order to effectively prevent blowout accidents and create a safe working environment.
1. Wireline BOP
3. A wireline BOP is one of the major well control equipment used to seal cables in production processes ranging from drilling, formation tests to extraction. The wireline control valve adopts the round ram and can be opened manually or hydraulically.
1. Single-Ram BOP
3. A single-ram BOP is a well control device, common in drilling operations like small wellbore drilling, well overhauling and formation tests. The single ram is oblong and the BOP can be opened manually or hydraulically.
1. BOP Spare Parts
3. JUDALAI supplies a wide range of BOP spare parts which can adapt to different operating environments featuring high temperatures, low humidity and high H₂S concentrations.
