Drilling machine is really a kind of gear that is utilized to drill in the earth surface. It includes some large-scale Engineering Drilling Rigs that are utilized to drill water nicely, oil well, and nature gas well. In the same time, it also consists of some small size equipments which can 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 set up underground item equipments. It could be faxed on some moving devices like 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 .
Numerous
countries, such as America, France, Canada and Germany, all developed various
oil drilling rigs on and off to meet all type needs of oil and gas reservoir at
various areas. There is the improvement history of drilling rigs.
1. AC frequency
conversion electric drive petroleum drilling machine. The core technologies of
this machine is AC variable frequency speed control technology. It is a
complete cross technology which involved motor theory, automatic control
theory, the circuit topology theory, power electronics, micro-electronics and
pc technology. It is an organic mixture of modern higher technologies and oil
drilling machinery, and has powerful vitality. It's the development trend of
modern petroleum drilling rigs.
two. Laser
drilling rig. Compared with conventional drilling machines, laser drilling rigs
don?¡¥t require drilling fluid, drilling bits, drill rods, oil tube and casing
pipe, these characteristics would reduce the costing greatly. Meanwhile, laser
drilling rigs have many other possible advantages, like light-weight, small
floor space, fast speed, and could through various types of rocks. Probably the
most essential benefit of laser drilling rig is that it's a clean break and may
drill, melt and evaporate rocks. Due to this, there's no cutting back towards
the ground and have a smaller impact around 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 leading drive device, hydraulic system and a few other parts.
Its motion mode is converted easily. It has small volume and light weight. It
could be used in some conditions which possess a higher requirement of drilling
rig volume and quality when the reliability of hydraulic elements may be
improved in the future.
4. Continuous
soft tube of oil drilling rig. Continuous soft tube is a kind of steel tube
with high intensity continuous manufacturing. Nowadays, the continuous length
of the tube can reach to 7620 meters. The advantage of this drilling technology
is mainly embodied in low price, brief drilling time. It could achieve
synchronization in 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
security. Continuous soft tube of oil drilling rig is very suit to drill small
hole well and the improvement of offshore platform and also the marginal oil
field, for it has small floor space, small soft tube size and its equipments
can be installed, tear downed and carried convenient. But the application of
continuous soft tube technology was limited by some factors and only may be
used in nicely drilling. On the other side, its service life is shorter than
other equipments.
5. Casing
drilling rig. This is a new business technology of nicely drilling. Instead of
drill rods, it use casing pipe to drill wells. It use leading drive device that
is drove by electric and hydraulic. Generally, 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 from the torque to drill rotary.
This structure is extremely simple to alter the drilling bit and the operation
is very handy and fast.
As the quickly
improvement of economy, The study and manufacturing degree of oil exploration
gear in our country has made great progress. You will find much more and more
expert drilling equipment producers in China. Such as, you will find a great
deal of manufacturers create diamond bits which is utilized in borehole
drilling machine at present China. There are also a lot of drill rods producers
and water nicely drilling gear surppliers, you are able to discover each kind
and model you would like online.
