The number of drilling machines and drilling equipments

Drilling machine is really a sort of gear that is utilised to drill in the earth surface. It consists of some large-scale Engineering Drilling Rigs which are utilised to drill water nicely, oil nicely, and nature gas properly. Inside the same time, additionally, it consists of some modest size equipments which may be moved by a single individual, and they are called twist drill or hand drilling machines. Drilling machine can obtain the sampling of underground mineral or install underground item equipments. It can be faxed on some moving devices like truck, trail auto and pathway, or be faxed stationary on land and offshore structure, for example drilling platform, or be called as Offshore Oil Rig.

Several countries, for example America, France, Canada and Germany, all developed different oil drilling rigs on and off to meet all type demands of oil and gas reservoir at different places. 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 handle technology. It's a extensive cross technology which involved motor theory, automatic manage theory, the circuit topology theory, power electronics, micro-electronics and pc technology. It is an organic mixture of contemporary higher technologies and oil drilling machinery, and has strong vitality. It really is the development trend of modern petroleum drilling rigs.

two. Laser drilling rig. Compared with traditional drilling machines, laser drilling rigs don?¡¥t want drilling fluid, drilling bits, drill rods, oil tube and casing pipe, these traits would reduce the costing tremendously. Meanwhile, laser drilling rigs have several other possible advantages, for example light-weight, small floor space, quick speed, and could via different forms of rocks. Probably the most important benefit of laser drilling rig is that it's a clean break and can drill, melt and evaporate rocks. Due to this, there is no cutting back for the ground and have a smaller sized influence 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 top drive device, hydraulic technique and a few other parts. Its motion mode is converted very easily. It has small volume and light weight. It would be utilised in some conditions which have a high requirement of drilling rig volume and high quality if the reliability of hydraulic components could be improved inside the future.

four. Continuous soft tube of oil drilling rig. Continuous soft tube is actually a sort of steel tube with higher intensity continuous manufacturing. These days, the continuous length on the tube can reach to 7620 meters. The benefit of this drilling technology is primarily embodied in low cost, quick drilling time. It can obtain synchronization between measure and drilling and be utilised in re-drilling old wells, deepen the borehole and sidetracking.

Meanwhile, it also may be used in underbalanced drilling operation to ensure operation safety. Continuous soft tube of oil drilling rig is extremely suit to drill little hole effectively and also the development of offshore platform and the marginal oil field, for it has small floor space, little soft tube size and its equipments can be installed, tear downed and carried handy. However the application of continuous soft tube technology was restricted by some elements and only can be employed in nicely drilling. Around the other side, its service life is shorter than other equipments.

5. Casing drilling rig. That is a brand new market technologies of properly drilling. As an alternative to drill rods, it use casing pipe to drill wells. It use top drive device which is drove by electric and hydraulic. Typically, it is installed on trial car and to transmit the torque via the sleeve. Then this energy will drive the drilling bit which is installed on the bottom from the torque to drill rotary. This structure is extremely simple to change the drilling bit as well as the operation is quite practical and speedy.

As the rapidly development of economy, The research and manufacturing level of oil exploration equipment in our nation has made wonderful progress. You'll find more and more specialist drilling equipment producers in China. For example, you will find a whole lot of producers generate diamond bits that is employed in borehole drilling machine at present China. You will find also a great deal of drill rods makers and water properly drilling gear surppliers, you can locate every type and model you desire online.
