The electromechanical compound drilling rigs include specifications such as ZJ30/1700LDB, ZJ40/2250LDB, ZJ50/3150LDB, and ZJ70/4500LDB.

Technical Features

The winch and mud pump are driven by a combination of "diesel engine + hydraulic torque converter (or coupling forward gearbox) + chain parallel gearbox"; the rotary table is driven by an AC variable frequency motor or DC motor, which enables stepless speed regulation, breaks through torque limitations, and improves drilling performance;

The host module adopts a "front high, rear low" layout, with the power and transmission systems installed at a low position;

The main brake adopts a hydraulic disc brake, while the auxiliary brake utilizes an electromagnetic eddy current brake. The winch features internal gear shifting, with pneumatic remote operation for quick and convenient gear changes;

The base adopts a box-block structure or a "rotating front platform and block-mounted back platform" design, featuring a flat drill floor, ample operating space, good power coordination, and high power utilization efficiency;

It can meet the requirements for migration between well locations during cluster drilling;

Through PLC, logical control, monitoring, and protection of the entire drilling process can be achieved, featuring data storage, printing, and remote transmission capabilities.
