Type ZQ drill pipe power tong1.7.1

ZQ drill pipe power tong is an ideal wellhead tool for oil drilling, widely applied in

make-up and breaking-out for well drilling and repairing on offshore and land. Open-

throat design of the ZQ series with high mobility allows escaping from drilling pipe

freely. The tong is a combination of spinning tong and torque tong. It substitutes

cathead, suspension tong and spinning rope in making-up and breaking-out. The

tongs are designed and manufactured according to API Spec 7K Specification for

drilling equipment .

1.8 Bushing

Roller Kelly bushing1.8.1

Roller kelly bushing is a necessary tool for drilling. It is to drive kelly

spinner by matching with master bushing. Through rotating of four

rollers, the friction between rollers and kelly pipe is reduced and

service life is extended. For different sizes of kelly pipe and

hexagonal pipe only need to change corresponding rollers. To

connect with rotary table, there are two transmission styles (square

and pin). The product is designed and manufactured according to

API Spec 7K Specification for Drill Equipment .

2BitsIntroductionsAs per their structure, drill bits can be divided into drag

bits, roller cone bits, diamond bits and coring bits.

China is a major manufacturing base of bits, it is ranked

first in Asia and third in the world china owns

intellectual property rights and its technology have

reached the international advanced level. Leading in the

drill bit cutting teeth materials technology, bearing

unique structure and materials, new technology of drill

bit hydraulics, new products represent world's

development trend in the independent R & D high-

speed motor drill series, hard formation bits series and

non-standard size series.

China have advanced laboratory to test drill bits

structure and functional unit, calculated laboratory, be

able to carry out experimental evaluation of drill bits all

units including cutting structure, bearings, seals and

hydraulic systems.

Achieved from basic research, application of new

technologies, product development and manufacturing

research to product application, services and improve of

the virtuous circle, so technical reserves are backing of

the product development and marketing technology

services. They based on 3D CAD software and product

data management, throughout the life cycle of the

product to conduct a comprehensive technical

management, to make product development to achieve

fast, accurate and to maximize the timeliness and

functionality to meet market demand.

Through the application of lithology tester, Real-time

test mechanics parameters of the normal atmosphere

and confining pressure in the drilling of rock strata (such

as hardness, plastic coefficient, drillability, triaxial

compressive strength, elastic ratio and poisson's ratio,

etc.). For optimizing bit selection to provide reliable data

on formation rock properties, more accurately the type

of drill bits to provide a reasonable.

In the during use, the actual drilling time, footage,

mechanical drilling speed, hydraulic parameter, drilling

cost and other factors will affect the drilling efficiency

compared to the design estimates, and classification of

the wear assessment to improve the drill bit of the

design and lectotype.

2.1.3 SUPER-MD super-high speed motor bit

The use of turbo-drill tool, with the 11 5/8inch and 8 1/ 2inch drill bits, from 400rpm to

600rpm, service life of normal cone bits is about 10 hours usually. For working situation

with super high rotary speed, drill bit used roller-journal bearing and metal-sealing,

provided bearing reliability and long life. We have also developed cutting and extended

double nozzle hydraulic structure. SMD of the service life can reaches to more than 30

hours at the work situation of above 400 RPM.

2.1.4Petroleum exploration has been developed to deep formations gradually, in deep

formations (compact plastic mudstone, lava and granite etc.,), low ROP restrict the

economic of development in deep well or super-deep well. Failure mode, such as tooth

break, tooth wear, cone tip wear and bit diameter shrink etc., usually appear when

conventional cone bits drill in hard formations. So we have developed HF series bit for hard

formations through analyze and research these failure modes deeply and make use of

advanced computer 3D simulation technology and lots of platform experiments.

Result in site shows HF series bit has the advantages of long service life, high reliability, fast

ROP and strong gage protection ability etc.. HF series bit is the ideal choice for drilling in

hard formations and strong abrasive formations effectively and safely.

2.1.5SWT high efficiency steel tooth bit

Abradability of teeth of conventional steel tooth cone bit is worse; tooth shape structure is

lack of optimization, which leads to decrease of average ROP. SWT series steel tooth bit

with high efficiency can solve these problems, with strong wear resistant teeth and fast

ROP, bit can work more stably, which is more suitable for drilling in soft or middle soft

formations with high rotary speed.

Application of SWT series steel tooth bit with high efficiency is the best way to solve the

problem of increasing drilling speed in higher part of well.

up jar .Therefore ,it must be run in conjunction with CSJ type super jar or YSJ type hydraulic

up jar .Its function mainly is to supply acceleration to the upper end of the jar during the

free jarring stroke .With a special function ,the intensifier is essentially a fluid spring which

not only can accelerate the up jarring action but also make the jarring action directly to

strike on the fish and reduce damages to the drill tool and fishing tool .

4.2Shock Absorber Type SJ should be connected with the drilling string close to the bit. It can

reduce or absorb both longitudinal and circumferential vibration of the drilling string in

drilling operations. It can achieve the optimum combination of drill pressure and drill

speed, reduce the drilling cost and promote the drilling efficiency.

Replaceable sleeve spiral stabilizerThe replaceable sleeve stabilizer are available with two-piece and three-piece construction. The three-

piece construction stabilizer is made of a body and a centralizing body(refer to sleeve replaceable). The

advantage is that the sleeve can be changed quickly and easily after sleeve hardfacing is worn-out. This

kind of stabilizer is especially suitable for working in directional well .

The kelly cock valve ,which is a manually operated ball valve run in the I.D of drill string ,is one of

effective tool for preventation from blowout .The kelly cock is divided into upper kelly cock valve and

lower kelly cock . The upper kelly cock is connected between lower end of swivel and upper end of kelly.

The lower kelly cock is connected between upper end of drillpipe and lower end of kelly or connected

between lower end of kelly saver subs. The kelly cock features a simple operation, the kelly cock can be

opened on or closed off by only turning the special operating spanner at 90 degrees according to

indicating direction.During drilling operation,in order to avoid serious well kick or blowout accident, the

kelly cock shall be connected at upper end and lower end of kelly.

operate.When blowout is going to be happened,the thread connections of the Kelly are

screwed out immediately and the back pressure valve is put into the I.D. of drill pipe and then

pumped downward to the required place.Thus the blowout accident can be prevented.The

tool is consisting of landing sub and check valve assembly.The landing is thread connected

with stop ring and tightened on and put into downhole with drill string .The landing sub is

used as a sub above drill string before check valve is run in downhole.

Reverse circulation fishing magnets8.5

CLF type fishing magnet in petroleum and geology exploration is used for fishing of small fallen objects in the down

hole.With some of advantages such as simply structure, easy to operate, reliable performance, small size and

lightweight,it is equipped with permanent magnet iron which can attract small objects such as teeth wheel, palm,

tong teeth and tool so that small objects in down hole are fished and the well bottom is cleaned up.

8.6The LL-F type reverse circulation junk basket is used to retrieve all types of small junk objects such as

cone,cutter,hand tool and junks from the bottom hole.During drilling operation,it produces a local

reverse circulation of fluid at well core so as to effect a complete recovery of junk in the junk basket

.Especially when PDC bit is used ,cleaning bottom well by the tool becmes very necessary to ensure the

bit with a normal application.The reverse circulation junk basket therefore becomes an essential tool in

oil ,geology exploration and drilling engineering.
