The same performance conclusion. Among them, the change value is caused by different materials and processes, and the drilling depth of the drill pipe is related to the torque of the drill pipe, but it is not determined by the drill pipe torque
The drilling depth is determined according to different geological conditions and the selection of drill pipe and drill bit type suitable for large trailer drilling RIGS. In this way, the torque of the drill pipe and the rig is selected well, and then selected according to the geological conditions of the operation
After selecting the corresponding drill pipe, select the matching drill bit to apply I. Of course, these are theoretical data, and specific problems can be analyzed in the construction process.
Drill bit is one of the important drilling tools in water well drilling rig. It can be said that without drill, large trailer drill can not start production normally, which shows the importance of drill bit in water well drilling rig.
For different types of water well drilling equipment, different drill bits need to be matched in production, water well drilling equipment should pay attention to the following aspects when selecting drill bits: 1
When producing in good soft rock, the speed of research is faster, and it is necessary to choose the one with larger slag discharge amount and higher slag discharge quality, which is to choose the four-wing shape. 2, when it is produced in hard rock, due to the rock
The strength is large, and each column tooth and drill bit need to bear a larger amount of load, so it is necessary to choose a drill with a higher strength of the drill body and column teeth. 3, when drilling rocks containing clay, by
When the clay is relatively loose, resulting in frequent blockage of the slag hole, you can choose the side slag drill. 4, trailer rig manufacturers can choose chock when drilling in the rock with good toughness
Shaped tooth drill to ensure safe production.
The principle of disassembly of trailer drilling rig is generally to disassemble after installation, and disassemble after installation. The following matters should be paid attention to when disassembling drill accessories: The gas, liquid and water pipelines should be sealed and kept open
Clean the pipe inside and interface of the drilling machine to avoid debris entering. When disassembling the drilling machine, the fasteners should be packed separately and labeled or packed into the packing box. Spiral for connecting everywhere,
Nuts should be packed separately to avoid mixing high-strength screws and nuts with other screws and nuts. The software of the air system should avoid oil, and the external threads of each pipeline should be wrapped with clean plastic cloth to avoid threads
Bruise and keep tube clean. It is strictly prohibited to fall and touch when disassembling and hoisting large trailer rig, so as not to damage the parts. If longer distance transportation or long time storage is required, it should be made to prevent rain, moisture and rust
Manage, and make the packing box packaging, fill in the packing list. All liquids (oil, water) in the equipment should be discharged clean.
The trailer drill uses the weight of the drill tool itself to impact the formation. At the lower end of the drill tool are several sharp-angled grips that can be tensed. As the drill tool moves downward under its own weight, the grips open and cut into the rock
Then the hoist lifts the drilling tool through the steel wire rope. In the closing process, the grasping flap grabs the rock debris into the cone, and the rock debris is discharged from the wellhead. The drilling depth is usually 40 ~ 50 meters, and the depth is 100 ~
One hundred and fifty meters. Wire rope percussion drill. It is composed of the mast and the lifting pulley installed on the top, the steel wire rope, the impact mechanism, the drilling tool, the motor, etc. When the trailer rig manufacturer works, the motor is on
The transmission device drives the impact mechanism, drives the steel wire rope to make the drill tool move up and down, and cuts into and breaks the rock formation by the weight of the drill bit itself when moving down, and pulls by the steel wire rope when moving up. drill
The head stroke is 0.5~1 m, and the impact frequency is 30~60 times/min. The cuttings are removed from the surface by the sand pumping cylinder, and the drilling and removal of cuttings are carried out simultaneously.
Maintenance of trailer rig: clean the surface of the rig, pay attention to the cleaning of the base slide, vertical shaft, guide rod and other surfaces, and maintain good lubrication; Check all exposed bolts, nuts, and seals
Whether the dangerous lock nails are firm and reliable; Lubricate as required; Check the oil level of transmission and transfer box; Check the oil level of the hydraulic tank; Check oil leakage and gas leakage, and eliminate them; Eliminate within the class
Other faults occur. Weekly maintenance of the rig: maintenance of the shift; Vertical axle box lubricated grease; Remove oil dirt or dust from hydraulic chuck and lower chuck; Moisten according to weekly maintenance requirements
Smooth; Clean the inside surface of the lock. Large trailer rig monthly maintenance content: weekly maintenance content; Remove the chuck, clean the slips, slip seat, dish spring, etc., and change the oil of the thrust bearing; to
Beam bearing with lithium grease; Clean the tank filter and replace the deteriorated hydraulic oil; Check the lubricating oil in the gearbox, transfer box and gyroscope, and replace it in time if it deteriorates; Check the parts
If there is damage, replace it in time.
