Development Trend of Oil Drilling Rig
Release time:
2020-03-31
Since the beginning of the 21st century, the level of automation, digitization, intelligence and informatization of oil drilling rigs has developed rapidly. The whole drilling rig is developing in the direction of AC frequency conversion speed regulation electric drive oil drilling rig (AC-GTO-AC). With the rapid development of AC frequency conversion technology, AC frequency conversion electric drive oil drilling rig will replace the SCR DC drive drilling rig, the drilling rig has the existing mechanical drive drilling rig and DC drive drilling rig incomparable superior performance, will become the development of land and offshore oil drilling rig replacement products.

In the future, the characteristics of oil drilling rig development are:
(1) Specialized drilling rigs have developed rapidly. Such as desert drilling rigs, offshore drilling rigs, inclined well drilling rigs, slim hole drilling rigs, deep well drilling rigs, coiled tubing drilling rigs, etc. that adapt to various environments and technological developments.
(2) The scale is developing in the direction of polarization. Deep well oil drilling rig tends to be large (1500M,MAX12500KN), portable drilling rig tends to be small (vehicle based).
(3) The drilling rig control is automated and intelligent. Top drive, disc brake technology gradually mature, electric control technology, hydraulic drive technology and reliability gradually improved.
(4) Vigorously develop new oil drilling rigs, using humanized design, advanced mechanical automation, efficient drilling rig operation and monitoring system, modular device, in order to improve rig migration, and ultimately improve drilling efficiency, greatly reduce drilling costs.
