How to use the Drill Bit properly

July 26 , 2022

The drill bit plays a pivotal role in the drilling process of water well drilling rigs. The quality of a drill bit directly affects the efficiency of water well drilling and the quality of the hole, so we need to pay attention to the selection and use of the drill bit. During the drilling process, the operator should pay attention to the drilling usage of the drill bit to make the drill bit better for production operations. Several aspects that need to be paid attention to in the drill bit of the water well drilling rig: 1. After the drill bit of the water well drilling rig is drilled into the structure, the center drilling tool needs to be replaced in time. First, the bottom of the hole needs to be cleaned, and then the residue at the bottom of the hole is blown clean. The tool is slowly lifted up, and it is most suitable when the lifting force is just enough to lift the drill tool. 2. The drill bit of the water well drilling rig is summarized during the drilling process. It is also necessary to carefully observe the follow-up situation of the casing, timely understand the...

Advantages of the Tricone Bits

July 18 , 2022

At present, whether in domestic construction or abroad to contract water well projects, the drilling technology of roller cone bits is generally adopted, especially in the construction of deep water wells and geothermal wells. From the field of use of roller cone bits in recent years, it has been extended to pile foundation construction, trench-less engineering construction, coal mine gas discharge well construction, the application scope is constantly expanding, and the social and economic benefits are very significant. Engineering practice has proved that the use of roller cone drilling technology has no special requirements for formation and groundwater conditions, and has the characteristics of good adaptability and wide application range, and should be vigorously promoted and applied. Compared with the general barrel drilling and core drilling efficiency, the drilling process of the roller cone bit is one to several times higher, and the life of the bit is also long. Dozens of meters to 100 meters are generally not a problem, the cost is low, and the one-time investment is not large. During the drilling process, the pure drilling time is increased and the auxiliary time is shortened (sometimes drilling is carried out only once in several shifts). The drilling...

Classification of water well drilling rigs(VI)

July 05 , 2022

Second, according to the type of drive device Water well drilling rigs can be divided into the following categories according to the type of driving equipment: 1. Electric-driven drilling rig: It is mainly powered by an AC motor to drive the drill pipe to the turntable. It is equipped with a water tap, a kelly, a lifter, etc., and the pressure and pressure are realized by its own weight and a winch. 2. Mechanically driven drilling rig: It is mainly powered by a diesel engine to drive the drill pipe to the turntable. It is equipped with a water tap, a kelly, a lifter, etc., and the pressure and pressure are realized by its own weight and a winch. 3. Hydraulic drilling rig: The power head is provided with hydraulic power to drive the drill pipe. The power head is both a faucet and a lifter. It functions as a drawworks when raising and lowering the drilling tools, and functions as pressurization and decompression when drilling.

Safety precautions during mining blasting

July 05 , 2022

Safety precautions during mining blasting Due to careless prevention, mine blasting often causes serious safety accidents, causing serious loss of personnel and property. What should be paid attention to in mine blasting safety? Pay attention to the following safety points during mine blasting: Preventive measures for safety accidents caused by detonating tubes: 1.There must be no dead knots in the detonation pipe network. There should not be any seams in the hole. 2.When using a detonator to detonate the detonating net, the end of the detonating tube cannot be connected to the direction of explosion of the detonating tube. 3. Establish a good detonation network. In order to prevent the influence of stray current on the network, we should carefully check the surrounding area to ensure that there are no metal objects on the surface. 4. After inserting the detonator into the cassette, fasten the detonator and the cassette with a rope. When handling primary explosives, the detonator must be placed in the reserved hole of the primer. The ban came out of the explosive tube. 5. After all filling operations are completed, the connection between the surface detonator detonation networks should be gradually carried out from the end of...

Classification of water well drilling rigs(V)

June 27 , 2022

Water well drilling rigs can generally be classified by various methods such as assembly form, drilling depth, driving equipment type and drilling process. 1. Divided by drilling depth Water well drilling rigs can be divided into the following categories according to the drilling depth: 1. Shallow well drilling rig: the drilling depth is not more than 300 meters 2. Medium-deep well drilling rig: drilling depth in the interval of 300-800 meters 3. Deep well drilling rig: drilling depth is in the interval of 800-2000 meters 4. Ultra-deep well drilling rig: drilling depth exceeding 2000 meters
