Top drive drilling equipment is a new type of oil drilling equipment used to replace rotary table drilling, and is known as one of the three revolutionary technological achievements of modern drilling equipment.
BPM top drive adopts advanced and mature AC variable frequency drive technology, which has the advantages of precise torque and speed control, flexible electrical system drive mode, and the motor operation mode can be directly selected on the driller’s console (no need to modify user programs or system parameters) , The control mode is convenient and flexible, which is the first for the BPM top drive.
The top drive of Beijing Petroleum Machinery adopts ProfiBus field bus control technology, adopts optical fiber communication or ProfiBus cable communication, and has strong anti-electromagnetic interference ability. The electrical control system adopts industrial control computer, with friendly user interface, switchable between Chinese and English interfaces, and you can browse all control information, including: operation history, alarm records, running data curves, help files, etc. Beijing Petroleum Machinery’s top drive is the first.
The top drive of Beijing Petroleum Machinery adopts a lifting system with double load channels. The lifting ring of the lifting ring does not pass the main bearing. The axial bearing of the rotating head adopts a large thrust bearing, which can rotate 360° under the load condition, which is convenient for on-site operation; the lifting ring can be tilted forward and backward It is tilted and has the function of floating in the neutral position; using the side-mounted back pliers commonly used in the industry, the pliers can float up and down in both directions in the full range, which is convenient to use the make-up and break-down function of the top drive to remove and install the adapter and IBOP.
Beijing Petroleum Machinery’s top drive is easy to operate, safe and efficient, and has all the advantages of a large top drive system, including:
It can be made up and drilled upright, and the time of making up and unloading is reduced by two-thirds;
The drilling tool can be quickly connected to the drilling tool when it encounters an obstacle and a card during tripping, and the mud is circulated while rotating to perform reverse reaming and drilling reaming.
It can run continuously locked under rated torque;
The original shaft rotation positioning control function (Shaft Rotation Position Control), combined with the continuous control drilling technology using screw drilling tools, makes the directional drilling of horizontal wells easier and more accurate;
The top drive soft torque control technology analyzes and optimizes relevant parameters such as load, torque and rotational speed by collecting relevant parameters, and is intelligently controlled by the operating system to avoid the occurrence of downhole accidents, ensure drilling safety, and improve drilling efficiency;
The technical parameters are set reasonably, the degree of automation is high, and the program runs reliably.
