How to avoid the drilling rig getting stuck while drilling a well

Crawler water well drilling rig jammed drilling is a common problem in drilling operations, which seriously affects the construction progress and efficiency. In order to avoid stuck drilling, we can start from the following aspects:

1. Adequate preparation before drilling

Geological exploration: Understand the geological conditions of the drilling hole in detail, including the hardness of the rock layer, the development of joints, groundwater level, etc., in order to select the appropriate drilling tools and drilling parameters.
Selection of drilling tools: Select the appropriate drill bit, drill pipe and impactor according to the stratum to ensure that the drilling tools match the stratum.
Equipment inspection: Check the parts of the drilling rig carefully to ensure that the equipment is in good condition, the hydraulic system is normal, and the lubrication is sufficient. 2.

2. Reasonable control of drilling parameters

Speed and pressure: According to the hardness of the stratum and the type of drilling tools, set the speed and pressure reasonably to avoid the drill bit jamming caused by too high speed or too much pressure.
Flushing: Keep the drilling hole clean and discharge the drill cuttings in time to prevent the drilling hole from clogging.
Frequency of lifting: Regularly lift the drill to check the wear of the drill bit, and replace the worn out drill bit in time.

3. Pay attention to abnormalities in the drilling process.

Listen to the sound: Listen to the sound of the drilling machine, if there is any abnormal sound, stop the machine immediately for inspection.
Observe the drilling pressure: Observe the change of drilling pressure, if the drilling pressure increases suddenly, it may be encountered hard rock layer or the drilling tool jammed.
Measurement: Measure the drilling depth regularly, if the drilling depth is slow or stops, timely measures should be taken.

4. Other Precautions

Operator: The operator must be professionally trained and familiar with the performance of the drilling rig and the operating procedures.
Safety first: pay attention to safety and wear good protective equipment during the drilling process.

How to extend the life of drill pipe

1. When using a new drill pipe, the drilling rig manufacturer should make sure that the wire fasteners on the front cut-off (protecting the shaft head) of the drill bit are also close to the new one. A ring-buckled rotating head can easily damage the wire fasteners of the new drill pipe, resulting in leaks, snaps, and loosening, and so on. 2. In the use of drill pipe for a drilling, should be first “grinding new buckle”, which consists of, first smeared with silk buckle oil, and then use the drill rig full torque, and then open the buckle, and then smeared with silk buckle oil and then open, and so on for three times, you can avoid the new wear and buckle. 3. As far as possible to maintain the drill pipe under the ground and on the ground in a straight line, so as to avoid part of the side of the wire buckle force and cause unwanted wear and tear, or even jump buckle, pay attention to the rig anchored to avoid the construction of the force to move is very important. 4. The buckle...

What are the Basic Maintenance Methods for Water Well Drilling Rigs

Cleaning: After every day's operation, clean the mud, oil, and other debris on the rig in time to keep the rig clean. Checking lubrication: regularly check the lubrication points to ensure that the lubricant is sufficient and the grease is clean. Fasteners check: you can check whether the bolts and nuts of each part are loose and tighten them in time. Hydraulic system checks: you can check whether the hydraulic oil level is normal, whether there is no leakage phenomenon, and whether the hydraulic oil is clean. Lubrication system maintenance: regular replacement of lubricating oil, grease, cleaning oil filter, and oil tank. Hydraulic system maintenance: regular replacement of hydraulic oil, cleaning hydraulic filter. Cooling system maintenance: clean the radiator, and check the coolant level. Transmission system maintenance: check the tightness of the transmission belt, and replace the worn transmission belt. Electrical system maintenance: check whether the line is firm...

Use and maintenance of drill bits

Use and maintenance of drill bits: 1. Choose a suitable drill bit: Before using a drill bit, it is necessary to select the appropriate type and specification of drill bit based on drilling conditions and needs. 2. Installing the drill bit: When installing the drill bit, it is necessary to ensure that the connection between the drill bit and the drill pipe is firm, and to correctly install the cutting teeth of the drill bit. 3. Maintain appropriate drilling speed and pressure during the drilling process: Excessive drilling speed and pressure can lead to premature wear and damage of the drill bit, while too small can affect drilling efficiency. 4. Regular inspection and maintenance: Regularly check the wear of the drill bit and replace severely worn components in a timely manner. At the same time, it is necessary to regularly clean and lubricate the drill bit to extend its service life. 5. Storage and preservation: When storing and preserving drill bits, it i...
