Characteristics of Electrical Driven Drilling Rigs

Electrical Driven Drilling Rigs

▋ Basic parameters of drilling rig are in accordance with

GB/T23505-2009 Petroleum Drilling and Workover Rigs

●Stepless speed regulation of drawworks, rotary table, and

mud pump is realized as a result of adopting AC-SCR-DC

control system and power compensation technology in DC

motor driven rigs, thus a better drilling performance can be

acquired.

▋Hoisting speed, rotational speed of rotary table, and strokes

of mud pump can be adjusted as per needs owing to adopting

advanced VFD full digital control technology in AC variable

frequency motor driven rigs, thus drilling efficiency has been

improved.

▋A kind of integral rising slingshot substructure (height 7.5m,

9m, 10.5m) is used. The equipment on the drill floor and mast

can be installed at ground level and integrally raised to the

designated position with power of drawworks or hydraulic

wire-line winch.

▋ The hydraulic disc brake is used as main brake of the

drawworks. The braking torque is large and it is reliable to

brake. The brake handle is located in the driller’s cabin to

greatly reduce the intensity of driller’s labor.

▋ The rotary table is run by an INDEP drive and the chain

box has two gears. They are placed under the drill floor, on

which there is a large operation area.

▋ Either eddy current brake or Eaton Brake can be

considered as auxiliary brake of drawworks. A smooth,

labor-saving, easy control tripping operations is ensured.

The service life of brake rims (disc) and brake blocks is

efficiently prolonged. The drum is grooved and the wire line

is orderly wound round it. The collision avoidance systems

(over-spool, weight, and digital display) are available to

increase in the safety of drilling operations.

▋ The drawworks is provided with an automatic driller.

▋ Main components/parts are designed and made to API

Spec for ease of participating in international bids of drilling

rigs.

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 installed at ground level. Power is

transmitted through bevel gear and universal shaft to the

equipment on the drill floor. It is reliable in driving and easy in

assembly/disassembly.

▋The drawworks (40 and 50 model) utilize air clutch for

shifting gears, which are suitable for remote control.

▋Either band brake or hydraulic disc brake can be

considered as main brake of drawworks and either an eddy

current brake or EATON brake as auxiliary 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 mast is of open-front type without guy line. It is

integrally raised and installed at ground level.

▋ The substructure is of a box-on-box type. It is simple in

structure and easy to install. It is applicable for mounting

▋ZJ50/3150JD rig is of mechan-electric driven one. The drawworks

and the mud pump are mechanically driven and the rotary table

independently by DC motor.

▋Power of the rig comes from three G12V190PZL-3 diesel engines,

gear reducer casing & narrow V-belt compound and divides into three

branches: one is to run two 1300HP/1600HP mud pumps through two

universal shafts, the second is to run the drawworks through chain

box, and the third is to run one 800KVA/400V economic generator

through universal shaft.

▋Modular design is used. Three G12CV 190PZL-3 diesel engines,

reducer casing, and skid are taken as a transportation unit. Narrow

V-belt compound transmission unit and skid are considered as a

transportation unit. The dimensions meet railroad/highway

requirements.

▋The cantilever beam leg mast is installed at ground level and

integrally raised/lowered

▋The drill floor is 7.5m/9m in height, installed at ground level, and

raised/lowered together with the mast.

▋The drill floor is flat and spacious. On it there are the rotary table,

the rotary table drive, the hydraulic cathead, the hydraulic tongs, and

two 50kN air winches.

Introduction to ZJ50/3150LDB Drilling Rig

▋ZJ50/3150LDB rig is of mechan-electric driven one. The drawworks and the

mud pump are mechanically driven and the rotary table independently by AC

variable frequency motor

▋Power of the rig comes from three diesel engines (electronic), which drive

each working group after compounding through the coupler, reducer casing,

and integral chain box. Two universal shafts separately drive two

1300HP/1600HP mud pumps and chain directly drives the drawworks.

Universal shaft drives an 800KVA/400V economic generator.

▋The cantilever beam leg mast is installed at ground level and integrally

raised/lowered

▋The drill floor is 7.5m/9m in height, installed at ground level, and

raised/lowered together with the mast.

▋The drill floor is flat and spacious. On it there are the rotary table, the rotary

table drive, the hydraulic cathead, the hydraulic tongs, and two 50kN air

winches.

▋This kind of rig overcomes the problems existed in electric driven rig:

expensive cost in manufacturing, restriction between the rotary table speed of

mechanical rig and the mud pump stroke, longer transmission route, etc. It is

simple in structure and flexible in arrangement. It is a kind of an economical

and practical rig.
