Thread Types and Classification of Drilling Rig Pipe

According to the different thread, the drill pipe of oil drilling rig can be divided into ordinary drill pipe, square tooth drill pipe and weighted drill pipe. The common drill pipe is the main component of the drill string. The top is connected with the square drill pipe and the bottom is connected with the drill collar. Its function is to transmit torque, make the drill bit drill down and deepen the borehole.

Causes of drill bit slippage in engineering drilling rigs

The slippage of the drill bit can be overcome by first combining the single bucket footage depth on the display. Although the mud layer drilling resistance is small, as the slag inside the drilling bucket increases, resistance will be generated to the slag inlet, so the drilling resistance is increased, and the sound of the planetary reducer on the power head changes with the resistance, so listening to the sound of the power head can judge the footage. When the drilling resistance increases, the rotation speed of the power head also decreases, so the footage can also be judged by the rotation speed of the drill pipe.

Oil rig maintenance and maintenance knowledge!

Wipe the outer surface of the drilling rig clean, and pay attention to the cleanliness and good lubrication of the surfaces such as the slide of the drilling rig base and the vertical shaft. Check all exposed bolts, nuts, safety pins, etc. for security. Fill lubricating oil or grease according to the lubrication requirements. Check the oil level of the transmission, transfer case and hydraulic system oil tank.

Development Trend of Oil Drilling Rig

The level of automation, digitization, intelligence and informatization of oil drilling rigs is developing 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 variable frequency technology, AC variable frequency electric drive oil drilling rig will replace the SCR DC drive drilling rig.

Development Status and Level of Oil Drilling Rig at Home and Abroad

The development status and level of foreign oil drilling rigs The reason for the internationalization of the oil drilling rig market is that the structure of oil drilling rigs is complex, complete sets and technical difficulties, and the price is expensive. The price of each rig ranges from nearly 10 million yuan to tens of millions of yuan. There are only more than 4300 land oil drilling rigs of various types in the world. More than 200~300 offshore drilling rigs.
