Drilling machine is a type of gear which is
used to drill in the earth surface. It consists of some large-scale Engineering
Drilling Rigs which are utilized to drill water nicely, oil nicely, and
nature gas nicely. In the exact same time, it also includes some little size
equipments which may be moved by a single person, and they are known as twist
drill or hand drilling machines. Drilling machine can achieve the sampling of
underground mineral or install underground item equipments. It can be faxed on
some moving devices such as truck, trail car and pathway, or be faxed
stationary on land and offshore structure, like drilling platform, or be known
as as Offshore Oil Rig .
Many countries,
like America, France, Canada and Germany, all created numerous oil drilling
rigs on and off to meet all type requirements of oil and gas reservoir at
different areas. There is the improvement history of drilling rigs.
1. AC frequency
conversion electric drive petroleum drilling machine. The core technology of
this machine is AC variable frequency speed control technology. It is a
complete cross technologies which involved motor theory, automatic control
theory, the circuit topology theory, power electronics, micro-electronics and
pc technologies. It is an organic mixture of contemporary higher technology and
oil drilling machinery, and has strong vitality. It's the improvement trend of
modern petroleum drilling rigs.
2. Laser
drilling rig. Compared with conventional drilling machines, laser drilling rigs
don?¡¥t need drilling fluid, drilling bits, drill rods, oil tube and casing
pipe, these traits would reduce the costing significantly. Meanwhile, laser
drilling rigs have many other possible benefits, like light-weight, small floor
space, fast speed, and could via numerous kinds of rocks. The most important
advantage of laser drilling rig is the fact that it's a clean break and may
drill, melt and evaporate rocks. Because of this, there is no cutting back to
the ground and possess a smaller influence on the environment.
3. New Hydraulic
Drilling Rig. This sort of rigs is formed by double acting hydraulic
cylinder, moving yoke, lifting rope, balancer assembly, hydraulic cylinder
guide frame, the top drive device, hydraulic method and some other parts. Its
motion mode is converted effortlessly. It has small volume and light weight. It
could be utilized in some circumstances which possess a higher requirement of
drilling rig volume and high quality when the reliability of hydraulic elements
may be enhanced within the future.
4. Continuous
soft tube of oil drilling rig. Continuous soft tube is a kind of steel tube
with higher intensity continuous manufacturing. These days, the continuous
length of the tube can attain to 7620 meters. The advantage of this drilling
technologies is mainly embodied in low price, brief drilling time. It could attain
synchronization between measure and drilling and be used in re-drilling old
wells, deepen the borehole and sidetracking.
Meanwhile, it
also may be used in underbalanced drilling operation to make sure operation
safety. Continuous soft tube of oil drilling rig is extremely suit to drill
little hole well and also the development of offshore platform and also the
marginal oil field, for it has little floor space, small soft tube size and its
equipments may be installed, tear downed and carried handy. But the application
of continuous soft tube technology was limited by some elements and only may be
utilized in well drilling. On the other side, its service life is shorter than
other equipments.
5. Casing
drilling rig. This really is a new business technologies of well drilling.
Rather than drill rods, it use casing pipe to drill wells. It use top drive
device that is drove by electric and hydraulic. Usually, it is installed on
trial vehicle and to transmit the torque through the sleeve. Then this power
will drive the drilling bit that is installed on the bottom of the torque to
drill rotary. This structure is extremely simple to change the drilling bit and
the operation is very handy and fast.
Because the rapidly development of economy,
The research and manufacturing degree of oil exploration equipment in our
nation has produced great progress. There are more and much more professional
drilling gear producers in China. Like, there are a lot of producers create
diamond bits that is utilized in borehole drilling machine at present China.
You will find also a great deal of Drill
Rods Manufacturers Rock
Drilling Equipment Manufacturers
and water nicely drilling gear surppliers, you
can discover each kind and model you want online.
