The technical status and development trend of oil drilling rigs are discussed.

With the continuous improvement of drilling technology, especially with the continuous promotion and use of large displacement wells and horizontal wells, and the need of offshore deepwater drilling operations, the drilling depth is increasing, requiring the lifting capacity of the drilling rig to increase. With the increase of the lifting capacity of the drilling rig, along with the continuous improvement of the capacity of the devices such as winch, top drive, drilling pump, etc., it will cause continuous breakthroughs in the design and manufacture of the drilling rig, and require continuous improvement of the drilling speed. In order to continuously improve the drilling speed and drilling efficiency and reduce the labor intensity of workers, it is necessary to improve the automatic equipment configuration of the well site, mainly including automatic tools such as iron roughneck, automatic slip, automatic finger beam, power catway, automatic drill pipe box, pipe grabbing machine, etc.

Taboo of Deep Well Drilling Machine Maintenance

After adjusting the oil supply start time, the reason for checking the stroke margin is because the stroke margin of the plunger is related to the wear of the plunger and the sleeve. After the plunger and sleeve are worn, the plunger needs to move up a little more to start oil supply, which will delay the start of oil supply. When the adjusting bolt is loosened or replaced with a thicker adjusting block or washer, the lower position of the plunger will move upward, thereby reducing the stroke margin of the plunger. Therefore, when repairing and debugging the fuel injection pump, the stroke margin should be checked first to determine whether the fuel injection pump can still be adjusted.

How the drill pipes inside the water well drilling rig are connected

Connect the drill pipe to be connected to the previous drill pipe, and the rotator moves forward while rotating. When the trapezoidal conical thread of the water braid shaft is in contact with the conical thread of the newly connected drill pipe, immediately operate the holder handle, loosen the holder, and complete the connection of the drill pipe.

Knowledge of drilling rig

After the completion of the well, it is necessary to pump water to check the results. Under normal circumstances, it is only necessary to pump water once. The stable duration of the water level shall not be less than 8 hours. At the same time, the outlet flow of the dynamic water level of the well shall be measured. For large wells with water inflow at the bottom of the well, the thickness of the inverted filter layer and the particle size of the filter material shall be constructed in accordance with the design requirements. The mud and sediment at the bottom of the well must be removed before the inverted filter layer is laid. The filter material shall be sieved to remove mud and measured for standby.

Attention to water exploration and discharge of full hydraulic tunnel drilling rig

When the drilling rig is close to the old empty hole and it is expected that there may be gas or other harmful gas gushing out, there must be a gas inspector or mine rescue team on duty to check the air composition. If the gas or other harmful gases exceed the relevant provisions of the "Coal Mine Safety Regulations", the drilling rig must be stopped immediately, the power supply must be cut off, the personnel must be withdrawn, and the mine dispatching room must be reported to take measures to deal with it in time.

Precautions for Operation of Small Water Well Drilling Rig

After drilling the drill bit of the agricultural drilling machine, it is necessary to replace the central drilling tool in time. First, you need to clean the bottom of the hole, and then blow off the residue at the bottom of the hole. After the drill bit stops rotating, the drill bit in the agricultural drilling machine is drilled out. With a gentle upward lift, it is suitable when the lifting force is just enough to lift the drill bit.

Inspection Items of Drilling Rig_Oil Drilling Rig Manufacturer

Drilling rig is a complex machine, which consists of machines, units and institutions. Drilling rig is in the exploration or mineral resources (including solid ore, liquid ore, gas ore, etc.) development, drive the drilling tool to drill underground, access to physical geological data of mechanical equipment. Also known as drilling machine. The main function is to drive the drilling tool to break the rock at the bottom of the hole and lower or raise the drilling tool in the hole. It can be used to drill cores, ore cores, cuttings, gaseous samples, liquid samples, etc. to explore underground geology and mineral resources.

Advantages of Anti-well Drilling Rig Application_Oil Drilling Rig Manufacturer

According to the design requirements of the hole, the pillar is firmly erected. The upper and lower ends of the pillars shall be covered with planks. The horizontal shaft and snap ring are installed on the pillar according to a certain height and direction. Lift the machine through a manual winch, fix it on the pillar at the desired angle, and then adjust the hole of the drill bit.
