The core drilling rig is a kind of drilling rig suitable for cutting large areas in mountainous terrain or construction in forest areas. It has the characteristics of modular design, easy disassembly and assembly, high drilling efficiency, convenient transportation, low cost, and environmental protection. Capable of drilling in most cases to depths in excess of 350 meters in the HQ and over 500 meters in the NQ formation. The principle of the core drilling rig is roughly the same, and the main components are the drill rig, drill pipe, drill bit, etc. Power is provided by the drilling rig to drive the drill pipe and the drill bit to drill ...

Features of hydraulic core drilling rig 1-1. Adopt 53×59 hexagonal active drill pipe, which has strong rigidity and large transmission torque. 1-2. The machine adopts a taper clutch, which has the outstanding characteristics of large torque transmission, convenient operation and maintenance-free. 1-3. The planetary gear of the winch increases the modulus and installs a support frame, which greatly improves the hoisting and braking capabilities of the winch. 1-4. The four sets of bearings of the vertical shaft box are positioned to ensure that the gyrator has sufficient rigidity to cope with complex geological conditions such as gravel l...

How to Maintain the Drilling Rig Machine 1. Before the construction of the drilling rig, it is necessary to do a good job in the maintenance of the equipment: 1. Check the oil balance and oil quality of each fuel tank 2. Check whether the gear lubrication of each reducer is completed 3. Check for oil leakage 4. Check the flexibility of the lifter and the quality of the internal butter 5. Check whether the parts are loose or rusty 6. Fill the drill pipe puller with butter before each shift 7. Pay attention to whether the circuit relay is embrittled in time, and prepare replacement parts as soon as possible 2. Mid-to-late maintenance schedu...

What drilling methods does the drilling rig have? First, as far as the working principle of the drilling rig is concerned, there are mainly three drilling methods. The down-the-hole drilling method needs to be used in conjunction with an air compressor. it’s a good way to rock Mud pump rotary drilling is a more economical drilling method, ideal for soil, sand and clay formations, for rocks, the drilling speed is lower than submersible drilling. Using auger drilling, the drilling process does not require air compressors or mud pumps. However, it can only drill into soil, clay and sand. Second, in terms of drilling technology, we ha...

How to choose a water well drilling rig? 1. Drilling efficiency Drilling efficiency depends on formation, operator skill/experience, type of drilling machine and drilling method. 2. Price The price of the machine is a key factor in choosing a drilling machine and is an investment. The price of the machine increases with the diameter and depth of the drilled hole. 3. Operating costs Operating costs can significantly affect the profitability of a drilling business. Net profit is the money drillers receive from well users for drilling a well minus operating costs. 4. Availability of spare parts The availability of spare parts needs to be con...

While drilling a water well, my drill bit hit something hard and nothing seemed to get through it. Do you have any suggestions? Your drill bit is probably hitting rock, and while you can drill a well in rock, it will definitely slow down the process. Drilling through a large rock can slow the drilling down to half an inch per hour! However, the real problem is not the big rocks, but the small watermelon-sized rocks. On rocks this big, the drill bit has nothing to bite into, so it rolls off. While it’s not impossible to get around rock when drilling a water well, it can be so time-consuming that it may be impractical to drill a well ...

Drill bit plays a pivotal role in the drilling process for 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 have to pay much attention to the selection and using of the drill bit. During the drilling process, the operator should pay attention to the drilling usage of the drill bit to make it better for production operations. Below are several aspects that need to be paid attention to: 1. After the drill bit 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 the...

The core drilling rig is a kind of core drilling technology equipment, which can be mainly used for the general survey and exploration of metal and non-metal solid minerals. In addition, it can also be used in engineering geological survey, hydraulic geological survey, oil and gas exploration, water well drilling, etc. According to the structure of the gyrator of the engineering drilling rig, the core drilling rig system can be divided into three categories: vertical shaft type, rotary table type and mobile gyrator. Let’s take a look at the basic components of the core drilling rig. The core drilling rig is mainly composed of basic ...

Fully hydraulic water well drilling rig is a drilling rig in which all moving parts are driven and controlled by oil pressure. This kind of drilling rig realizes stepless speed regulation through a high-pressure variable oil pump, which can simplify the transmission mechanism and remove the gear box, which not only reduces the weight of the drilling rig, but also makes full use of the power. At the same time, the drilling speed is high, the work is stable, the operation is convenient and safe, and it is easy to realize automation and instrumentation, especially suitable for high-speed small-diameter drilling (such as diamond drilling).
