Drilling machine is a kind of gear which is
used to drill in the earth surface. It consists of some large-scale Engineering
Drilling Rigs which are used to drill water nicely, oil well, and nature
gas nicely. Within the exact same time, it also includes some little size
equipments which may be moved by a single individual, and they're 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 vehicle and pathway, or be
faxed stationary on land and offshore structure, like drilling platform, or be
known as as Offshore Oil Rig
.
Numerous countries,
like America, France, Canada and Germany, all developed various oil drilling
rigs on and off to meet all kind needs of oil and gas reservoir at various
locations. There is the development history of drilling rigs.
1. AC frequency
conversion electric drive petroleum drilling machine. The core technologies of
this machine is AC variable frequency speed manage technology. It is a
comprehensive cross technologies which involved motor theory, automatic manage
theory, the circuit topology theory, energy electronics, micro-electronics and
computer technology. It's an organic combination of modern high technology and
oil drilling machinery, and has strong vitality. It is the development trend of
contemporary petroleum drilling rigs.
two. 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 characteristics would decrease the costing significantly.
Meanwhile, laser drilling rigs have many other potential benefits, like
light-weight, little floor space, fast speed, and could via various kinds of
rocks. The most essential benefit of laser drilling rig is that it is a clean
break and can drill, melt and evaporate rocks. Due to this, there is no cutting
back towards the ground and possess a smaller sized impact around the
environment.
three. 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 leading drive device, hydraulic method and a few other parts.
Its motion mode is converted easily. It has small volume and light weight. It
could be used in some circumstances which possess a higher requirement of
drilling rig volume and quality if the reliability of hydraulic components can
be enhanced within the future.
4. Continuous
soft tube of oil drilling rig. Continuous soft tube is a type of steel tube with
high intensity continuous manufacturing. These days, the continuous length from
the tube can attain to 7620 meters. The advantage of this drilling technologies
is mainly embodied in low price, short 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 can be used in underbalanced drilling operation to ensure operation
safety. Continuous soft tube of oil drilling rig is very suit to drill small
hole nicely and the development of offshore platform and the marginal oil
field, for it has small floor space, little soft tube size and its equipments
may be installed, tear downed and carried handy. However the application of
continuous soft tube technologies was limited by some elements and only can be
utilized in well drilling. Around the other side, its service life is shorter
than other equipments.
five. Casing
drilling rig. This is a new industry technology of well drilling. Rather than
drill rods, it use casing pipe to drill wells. It use leading drive device
which is drove by electric and hydraulic. Usually, it is installed on trial car
and to transmit the torque through the sleeve. Then this power will drive the
drilling bit that is installed around the bottom from the torque to drill
rotary. This structure is very easy to change the drilling bit and the
operation is extremely convenient and rapid.
Because the rapidly improvement of economy,
The study and manufacturing degree of oil exploration equipment in our nation
has made great progress. There are more and more professional drilling gear
producers in China. Like, there are a lot of producers produce diamond bits
that is used in borehole drilling machine at present China. You will find also
a great deal of Drill
Rods Manufacturers
and water well drilling gear surppliers, you
can find each kind and model you would like online.
