A multi-layer Gravel Filling Sand Control Process
Multiple layers of gravel filling can be achieved through a single pipe string; The process column consists of an outer column (sand control column) and an inner column (filling service column); The inner and outer pipe columns are assembled at the wellhead according to the "piping table" and delivered to the sand control well section by the drill pipe; After setting the top packer, the external sand control pipe column is fixed in the sand control well section; After the hydraulic release of the inner column, it separates from the outer column; Lift up the filling service tool and complete multiple layers of filling from bottom to top. After filling is completed, lift out all service columns.

Gravel Filling and Sand Control Process for Barehole Horizontal Wells
Barehole horizontal well gravel filling process is one of the key technologies for sand control in barehole horizontal wells; during the whole construction period, the upper annulus of the top packer is always connected with the barehole, thus ensuring the stability of the well wall and effective sand control operation. The gravel-filled sand control tubular column of bare eye horizontal wells includes inner tubular column and outer tubular column, and the inner and outer tubular columns can work together to realise the reverse cycle pickling operation in place of mud filling; in the process of the operation, the tubular column is lifted up and lowered down, and the load indicator is used in conjunction with the locating hoop to realise the positioning, which is easy to operate and has the characteristics of accurate positioning.

Multi-layer Simple Anti-sanding Process
Multi-layer simple sand control process is a layered sand control process that does not require gravel filling in the casing. The simple sand control tubular column includes inner and outer tubular columns, which are assembled at the wellhead in accordance with the "Tubing Table" and delivered to the sand control well section by the drilling pipe; after pitching and seating the top packer, the tubular column will be pressurised, and the internal service tubular column will be discharged; after lifting up the inner tubular column, and seating all the segregation packers in turn from the bottom to the top, the drilling will be started to complete the sand control operation. The sand control operation is completed.
Bare Eye Simple Anti-sanding Process
Bare-eye simple sand control process is bare-eye non-gravel filling sand control process, bare-eye simple sand control service tubular column includes inner tubular column and outer tubular column, which can be applied in large inclined wells, horizontal wells and other complex structure wells. The simple structure and convenient operation of the tubular column greatly reduce the difficulty of the operation, save the cost of the operation and increase the production capacity of the well.
HBR Gas Storage Applications
The HBR Hydraulic Retrievable Packer is a single column packer for use in high pressure, large diameter or tubing transfer injection wells for oil and gas production. The HBR packer can also be designed for cable, or control line traversing to provide traversing capability. The HBR packer is connected to the tubing to be used in the well, and is sealed by applying pressure to the tubing. The HBR packer is designed to be lifted directly to unseal the tubing and cut to unseal the tubing in two recovery methods for selection.
Permanent Production Completion Tubing
Permanent completions for oil and gas wells are mainly used in long term production or injection wells, and the downhole tools involved need to be of high quality to cope with the harsh conditions of oil and gas wells and the need for longer service life.
