Petroleum exploration and development equipment refers to comprehensive equipment for oil and natural gas exploration, drilling, development, storage and transportation, including various types of geophysical prospecting and logging equipment, drilling equipment, oil and gas production equipment, downhole operation equipment, oil and gas gathering and transportation Equipment, offshore drilling platform equipment, etc. and related accessories and tools; oil refining and petrochemical equipment refers to the complete set of equipment required in the whole process of oil and natural gas processing and conversion, including general equipment (such as various process compressors, expanders, etc.) , pumps and valves, etc.) and medical equipment (such as reactors, towers, heat exchange equipment, industrial furnaces, storage and transportation equipment, medical machinery, etc.). The equipment specifications and parameters of the oil refining and petrochemical industry are determined by the process of the oil refining and petrochemical industry. The oil refining and petrochemical industry is a process industry. The requirements for automation are high, and it is required to be able to run continuously and stably for a long period of time, so there are high requirements for the reliability of the equipment. The oil and gas exploration, development and production process is characterized by multiple links, complex technologies, and high individual requirements.Design, manufacture and test standardAPI Spec 16A (3th) (16A-0100): specification for drill-through equipmentAPI spec 6A (20th) (6A-0474): Specification for wellhead & X-tree EquipmentNACE MR0175-2003/ISO 15156: Petroleum and natural gas materials in H2S environments.The main pressure-containing parts, such as body, bonnet, etc,. are using high-strength and high toughness alloy steel material. Allo of the parts are shape casting and followed by proper heat treatment.The bonnet is connected to the body by hinge which can be opened manually to replace the ram assembly. There are several alsots at the ram chamber botom of the body which can remove the mud and sand automatically during rams opening and closing, reduce the ram movement friction, and also improve the ram self-sealing.The special designed floating ram sealing structure can reduce the resistance during the ram opening and closing, extend the ram duration time by redcuing the packer wear, pervent rust between the body and ram, and can be dismantled easily.The material of main pressure-containing parts, such as body, bonnet, etc., are high-strength and high-toughness alloy steel which is processed and smelted under strict control to remove harmful compositions and non-metallic impurities through secondary refining and proper heat treatment, to ensure the quality of the BOP.The ram chamber of the body is overal shaped in orde rto reduce the stree concentration.The opening and closign of the bonnets and ram are operated through the BOP hydraulic control unit, the bonnet opening and closing can be the same operation, while the bonnet closing and ram opening can also be operated at the same time.The ram assembly design is also oval shaped, same as the body ram chamber.ANNUAR BOPRS-D Annuar BOP using sphercial packing element.RS-A Annuar BOP using the conical packing element, its upper housing and body are connected by radial latch for easy load and unload.Annuar BOP consists of the body, upper housing, dust-proof ring, pistion and packing element etc. It can seal all sizes of kelly, drill pipe, tool joint, drill collar, casing and cable, etc. and it can also completely shut off and seal the wellbore when there isn't any drilling tool in the well hole. This COP, when using accumulators, can allow the 18°/35° non-fine threaded tool joint pass through to carry out snubbing operation.
Overview
A Blowout Preventer (BOP) is a large, specialized valve or similar mechanical device, used to seal, control and monitor oil and gas wells to prevent blowouts, the uncontrolled release of crude oil and/or natural gas from a well. They are usually installed in stacks of other valves.
An Annular Blowout Preventer can close around the drill string, casing or a non-cylindrical object, such as the kelly. Drill pipe including the larger-diameter tool joints (threaded connectors) can be "stripped" (i.e., moved vertically while pressure is contained below) through an annular preventer by careful control of the hydraulic closing pressure. Annular blowout preventers are also effective at maintaining a seal around the drillpipe even as it rotates during drilling. Annular BOPs are typically located at the top of a BOP stack, with one or two annular preventers positioned above a series of several ram preventers. Annular preventers have only two moving parts, piston and packing unit, making them simple and easy to maintain relative to ram preventers.
The Annular BOPs manufactured by our company features a compact structure, which can seal Kelly, drill pipe sub, drill collar, and various shapes and sizes of cable. Meanwhile, the annular BOP can provide fixed pressure control during running and retrieving drill pipes.
