The rig
ZJ40/2250DB is a AC-VFD-AC drive 1000 Hp drilling rig with rated drilling
depth of up to 3500m (11483ft) with 127mm (5”) DP or 4000m(13123ft) with 114mm
(4-1/2”)DP. Rated maximum static hook load is 2250KN
Ø
On the basis of
comparing different kinds of rigs of a comparable depth, we took the main
advantages of different rigs and, at the same time, brought new ideas to the
rig. We have received patents for some of the techniques used. With many
characteristics such as advanced techniques, small well site footprint, high
drive efficiency and the capability of cluster wells drilling, the ZJ40 rig is
more suitable for drilling on the smaller well site when necessary. For
example when drill in a mountain area, farmland or in the city.
The
main advantages of this rig are as follows:
Ø
The mast is
assembled in several sections and lifted vertically so that during rig up, the
necessary installation area of the rig is smaller than those assembled
horizontally. Additionally, the lifting of the mast and the substructure uses
two sets of hydraulic winches and a very small hydraulic pump station, which
make the lifting of the mast and the substructure very simple and removes the
drawworks from the process.
Ø
The drawworks
is fixed on the ground with a separate base (different from a normal rig whose
drawworks is installed on the drill floor), so it does not take up any space
on the drill floor, which make the operating space on the drill floor very
large, and people working on the drill floor will feel very comfortable and
safe.
Ø
The drawworks
main brake uses the hydraulic disc brake instead of the traditional band
brake, which makes the driller’s operation easier (the driller just needs to
operate a small hydraulic brake control lever instead the heavy brake handle).
Additionally, no parts of the drawworks assembly need water cooling, which
makes the rig more suitable for cold climate use.
Ø
The advanced
SIEMENS 6SE71 VFD system is used to control all the AC motors used to drive
the drawworks, mud pumps, and rotary table providing excellent speed
regulation.
Ø
The SIEMENS VFD
controlled AC motor driven automatic drilling system is used on this rig.
Ø
When drilling
cluster wells, mast, substructure and drawworks move forward and other
equipment such as generator house and mud pump stay at their original
position.
Ø
The rig design
is suitable for top drive system installation.
