Petroleum Drilling Equipment
Introduction
In the 1950s, China began to manufacture petroleum drilling
equipment and their components and built its complete oil industrial
product system. The main petroleum machinery manufacturers have
set up a complete quality assurance system and obtained the

certificate of ISO 9000 quality assurance system and have been granted

the right to use API certificates.
CAOIMPEX, with expertise in complete rig package supply, chooses the

best quality products in, but not limited in China, to match with each
other to get the best performance of a complete rig. Presently, we have
been able to supply 1, 000-12, 000 m, (3, 280 ft-40, 000 ft) land drilling
rigs, mechanical drilling rigs, SCR electrical drilling rigs and VFD
electrical drilling rigs. For small rigs under 1, 200 HP, we can supply fastmove type rigs, either truck-mounted, skid-mounted or trailer-moved.
CAOIMPEX can also provide matched equipment and tools to the rigs,
such as power system, air system, mud pumps, BOPs, motors, tanks,
mud treatment equipment, instruments, and cementing units, etc.
With more than 50-year experience, China has developed some new

rigs, all-on-trailer rigs, quick skid and cluster well rigs, extreme low
temperature rigs, etc.

D.C. motor driven drilling rig adopts an AC-SCR-DC power system. The drawworks, the rotary
table and the mud pump can accomplish step less speed.
For AC variable frequency motor driven drilling rigs. Any hoisting speeds, rotary speeds and
pump strokes can be adjusted and any speed regulation & power utilization of them can be
improved as a result of taking VFD and numerical control technology.
The hydraulic disc brake is used as main brake of the drawworks. Auxiliary brake of the

The chain box driving the rotary table is placed under the rig floor. There is a large operational
zone for ease of installing and aligning the rotary table.
Transmission of drawworks
The drawworks is provided with auto feed driller to realize auto drilling of main motor or small
motor.
The rotary table has a gearbox with two gears, which is chain or gear driven.
I.D. of swivel stem
The equipment on the floor and the mast can be installed at ground level and raised to
position with power of drawworks due to using a parallelogram integrally raising substructure

Notes
L-chain compound transmission DB-rotary table is driven by VFD
brake.
The chain driven rig is driven by the integral enclosed
compound chain box (or narrow V-belt) and coupling. During any
rig moves, it is unnecessary to dismantle the chains (or narrow Vbelt) for fast installation.
The substructure is of a box-on-box type. It is simple in
structure and easy to install. It is applicable for mounting B.O.P
installations.
