Series of Modular Drilling Rigs

Detailed Product Description

  Based on the experience of design and manufacture of truck-mounted drilling rigs for more than twenty years, We has jointly developed series of skid-mounted drilling rig with national research institute and oversea design company. The products cover conventional diesel engine chain-type drive, diesel engine & motor compound drive, VFD drilling rig, and conceptual BigEasy drilling rig with max. drilling depth of 9,840' (3000m), 13,120' (4000m), 16,400' (5000m), 22,960' (7000m), etc., which can meet different requirements in different areas and well sites, including sea, desert, plateau, and polar region. Mast, drawworks, substructure and their accessories can be in accordance with national standard specification for drilling rig and API 7K, 8C, 6A, 7F, etc.

OTHER MODELS : ZJ70D numeric modularized drilling rig

product description:
    ZJ70D drilling rig, designed to SY/T5609 standard and API specifications, is a SCR DC electric drilling rig. It can be used for 7000m drilling operations in the development of oil, gas and water wells. It is safe and reliable, and can be fitted with a top drive device.

features:
    1) With AC-SCR-DC one-on-two full numeric control electric driving power system, the drawworks, rotary table and mud pump have a good drilling performance. Stable starting, high driving efficiency and automatic evenly-distributed load.
    2) With international mature technologies and structures, the progress, reliability and standardization are further improved.
    3) Modularized design, orderly layout, convenient rig movement, excellent exchangeability.
    4) The deck equipment and mast are installed in low position, and lifted as a whole by the drawworks, to facilitate installation and save lifting job.
    5) Complete and good unitized parts to meet the requirements for different drilling depths.
    6) Equipped with hydraulic disc brake, auto driller and driller control room, to enable more safe, reliable and comfortable operations.
    7) Independently-driven rotary table to ensure high mobility.
    8) High efficient solid control system for different requirements for drilling process. Tank surfaces are flat and meet the requirements for HSE.
    9) The rig can satisfy the need for new drilling process. It can work at -20°C+50°C, humidity ≤90%(at +20°C) or other rough environments.
