1Drilling rigsIn 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 fast-

move 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

types of drilling rigs, including offshore drilling rigs, helicopter lifting

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

temperature rigs, etc.

Introduction

As per China Petroleum Industrial Standard, we define the rig model as below:

1.2Electrical Driven Drilling Rigs

1.2.1CharacteristicsD.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

drawwworks can be either an eddy current brake.

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.

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.

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

(height: 9m/10.5m).

Main components are made to API Spec.

1.3.1CharacteristicsPower by three-(or four)-diesel-engine linkages, which are

connected with couplers and reducer casings.

Easy installation and better sealing as a result of taking an

integral chain box or V-belt compound transmission unit.

The drawworks is equipped with the grooved drum and

shifting a gear for it is carried out by air cylinders. The

hydraulic brake is regarded as main brake and the eddy

current brake as auxiliary brake.

The drawworks is equipped with an auxiliary raising

device. Prior to starting the diesel engine, raise the mast in

advance. In case of the master clutch failure and power

failure to transferring to the drawworks, the device is used

for lifting the drill tools to reduce accidents and realize safety

drilling operations.

The rotary table is driven independently by AC variable

frequency motor and can accomplish step less speed

regulation with 0-240r/min. AC is supplied by an auxiliary

generator set.

Mechanical parts of rigs are in compliance with API Spec.

1.4 Mechanical Driven Drilling Rigs

1.4.1CharacteristicsThe drilling rig is driven by diesel engines, hydraulic coupling &

chain compound box or diesel engines, reducers & narrow V-belt,

which provides smooth mechanical power to the drawworks. A

number of hoisting speeds and rotary speeds are available.

The drawworks is divided into two sections so as to install the

main drawworks at ground level. The tapered gear box and

universal shaft transmit smooth power to the equipment on the

drill floor for easembly/disassembly.

The main drawworks utilize air clutch for shifting gears, which

are suitable for remote control. The catwalk is equipped with a

sand reel of entire & combination construction. The construction

can be separately lifted on the drill floor without a heavy-duty

crane.

The main brake system uses either a band brake or a hydraulic

disc brake. And the auxiliary brake adopts either an eddy current

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 V-

belt) 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.

2.9Design features

The rotor and stator are made of high quality magnetic materials and

subjected to heat treatment.

Coils are made of single polymide wire wrapped with glass fiber and are

dip coating of vacuum pressure in twice. The insulation level is Class F or H.

The cooling water is supplied by a circulating water pump to ensure that

the heat generated by the brake can be dissipated even under maximum

load.

To connect with the drum shaft by means of involute spline tooth clutch.

Design featuresThe power end: The housing is welded steel-plate construction. It is stress-relieved

after welding. The drive gears are involute type gears which allow smooth operating,

high efficiency and long life. The crankshaft is a hollow one-piece steel casting. The

power end is splash-lubricated.

The fluid end: The suction and the discharge flanges conform to ASA and API

specifications.

The piston rod is connected with an intermediate rod by means of clamps to realize

quick assembly & disassembly.

The valve seat bores have a bottom shoulders. The pistons and liners are lubricated

and cooled by an independently spraying pump to have a longer service life.

Versatility in expendables.

Open-face masts.

Raising mode: integral and bootstrap.

Masts are installed at ground level and divide into sections.

Masts stems are of beam structure for easy of assembly/disassembly and

transportation.

Two hydraulic cylinders (Left & Right) are provided to be used as snubber

when raising masts and as primary push-pull force when lowering masts.

Masts conform to API Spec. 4F, and are applied API monogram on them.

2.13Design features

Three kinds of substructures: box-on-box, two-step raising & swing-lift.

The box-on-box structure: The front platform is suitable for installing

standard BOP and the rear platform for installing heavy main drawworks

and transmission groups.

The two-step structure: The equipment on the drill floor can be

installed at ground level. The mast is raised when the drill floor is in the

lower position. Then the floor and entire mast are raised together. The

drill floor is equipped with two hydraulic cylinders, which serve the

function of snubbing while raising the floor and push-back while

lowering the floor.

The swing-lift structure: The substructure is raised integrally together

with the mast. The mast, the drill floor, and the equipment on the drill

floor are all installed at ground level and raised with power of drawworks.

The substructures conform to API Spec. 4F and are used API

monogram on them.
