4, drill summary of overall scheme

Rig adopts two 12 v190 as main power, the number one, number two, three interlocking machine and car, respectively with a belt drive two 1300 mud pump, a 300 kw generator, an automatic pressure fan, interlocking machine is number one trunk chain climbing drive high installation winch, winch chain drive rotary shaft.

After opening derrick, before the high low box type base, derrick lifting power of winch. Winch high installation, the main brake USES belt brake, the auxiliary brake USES air-cooled eddy current brake.

The machine modular design, installation is convenient, fast, easy to transport.

Five major parts, drilling

JJ225/42-5.1 K type derrick

Maximum hook load 2250 kn

Effective height of 42 m

At the bottom of the span 7.5 m

Drill floor surface span 7.2 m

28 MiLiGen drill pipe, drill pipe size (127 mm column contains 7 8 "drill collar) 4000 m

Platform installation height of 24.5 m, 25.5 m, 26.5 m

The wind resistance

A. stop drilling condition (no hook load, platform with vertical root) 36 m/s

B. preservation condition (no hook load, platform with vertical root) 47.8 m/s

C. the derrick 8.3 m/s or less

The structural type and accessories

Derrick with low installation, integral lifting down K type derrick, derrick subject by five sections around each frame and back beams, diagonal member composition before opening the overall steel frame structure, main stress member choose Q345B material of h-beam, derrick on plane contact between two paragraphs pin coupling structure, USES the diesel engine power through the winch lifting.

Derrick stand by support after the gasket increase or decrease in left and right is well head, find direction before and after the top wire to adjust on the derrick. Derrick left with a ladder to runaround, with 1 set of the ladder booster, set on the right side of the ladder to the platform. On both sides of the ladder with fold-down retainer.

Platform operated by the body, with the tongue and the railings outside panels. With active means beam, add safety chain, put on the machine body refers to beam placed on drill collar card board, drill pipe stop lever is equipped with safety chain. Pipeline and pulling device (installed in the position of the 1 m high), used for drill collar, drill pipe.

Derrick all welding position of weld specification, no slag inclusion.

Derrick on pipeline (including riser pipe, gas pipe,) layout is neat and beautiful.

On board level to pin with double d pin. All kinds of guardrail, ladders and rig derrick connection with single taper pin.

Ancillary facilities of derrick design to install the following:

2 sets escape device 1

1 set of lifting the buffer device (including high and low support, balance of hoisting rope and pulley)

Deadline holder 1 set (installed under the mast section on the right side)

2 crabs balance device, crabs, pulley 2, liquid gas tong pulley 1, pneumatic winch roller 2, drill pipe blowout box pulley 1;

1 set of riser, riser work station 1.

Mast height support each 1 set, 2 sets of derrick ladder.

(mechanical adjustable casing centralizer 1 set)

Derrick design in accordance with API.
