‌RockySea Petro Drawworks



Function

(1) During the drilling process, hang the drilling tools, feed in the drill string and drill bit, and control the drilling pressure.
(2) Use the cathead mechanism of the drawworks to tightly unload drilling tools and lift heavy objects.
(3) Provide different lifting speeds and weights for drilling operations.
(4) As the variable speed mechanism and intermediate transmission mechanism of the turntable.
(5) Use the sand drum of the drawworks to perform core extraction, oil testing, and other work.
(6) When using an integral lifting workover rig, it is used to lift and release the mast.
(7) Assist in installing drilling equipment and complete other auxiliary tasks.


Description

The drilling drawworks is the main lifting mechanical component of a rotary workover rig. Its main function is to provide a method for raising and lowering the traveling block. The steel wire rope is wound around the drawworks drum and passes over the overhead crane to reach the traveling block, allowing the drill string to move up and down with the rotation of the drum. The section of drill pipe line from the drawworks to the overhead crane is called a "fast line". Then, the drilling line enters the first pulley of the crown block, and for mechanical advantages, it is usually passed between the crown block and the traveling block pulley 6 to 12 times. Then, the rope leaves the last pulley on the overhead crane and is fixed to the support leg of the workover rig on the other side. This drill line is called the "dead line".

Modern Drawworks consist of five main components: drum, power source, reducer, brake, and auxiliary brake. This device can be powered by electricity (AC or DC) or directly connected to an internal combustion engine using a metal chain belt. The number of gears can be one, two, or a combination of three speeds. The main brake is usually manually operated by a long handle and can be a friction band brake, a disc brake, or an improved clutch. When no movement is required, it can serve as a parking brake. The auxiliary brake is connected to the brake drum and absorbs the energy released when heavy loads are reduced. This brake can use eddy current rotors or devices similar to water turbines to convert the kinetic energy of moving loads into heat and dissipate it.

The power cathead (winch) located on each side provides a device for driving pliers for connecting and disconnecting threaded pipeline components. The outboard cat head can be manually used with ropes for various small lifting operations around the workover rig.The front side of the drawworks usually has a pulley drive device that provides rotational power for the turntable, although on many workover rigs, the turntable is independently powered.

The drawworks of RockySea are divided into different types , such as single gear Drawworks and multi-gear drawworks. They mainly include the sand drum assembly, sand drum brake system, drawworks frame, cooling system, lubrication system, auxiliary brake, overhead crane anti-collision device, etc.
