What drilling methods does the drilling rig have?

May 23 , 2023

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. 1. The down-the-hole drilling method needs to be used in conjunction with an air compressor. it’s a good way to rock 2. 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. 3. 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 have 2 drilling methods. 1. Direct circulation drilling, where drilling fluid (air or mud) is passed through the drillpipe and cuttings are removed Through the space between the outside of the drill pipe and the hole wall. For reverse circulation drilling, double-walled drill pipe is required. Drilling fluid passes through the space between the inner wall of the outer tube and the outer wall of the inner tube. It is the most effective drilling method for cobblestone and sandy and earthy geological formations.

How to choose a water well drilling rig?

April 26 , 2023

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 considered when buying a rig. It is part of operating costs. If spare parts are not readily available, it means you have to pay more to get them, and it takes longer. All of this will inevitably affect the profitability of the land business.

Water Well Drilling Recommendations

April 15 , 2023

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 in a particular location. You can always try drilling a well in another location on your property, but there is no guarantee that the rock formation you hit won’t extend under the entire property.

How to use and maintain the Drill Bits

March 27 , 2023

How to use and maintain the Drill Bits 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 then the residue at the bottom of the hole needs to be blown clean. The tool should be 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 specific situation in the hole, and...

Drilling Rig Machine parts replacement process

December 23 , 2022

Replacement of throttle valve for drilling rig accessories: 1. Replace the valve plate and valve seat: remove the valve cavity pressure, remove the valve cover bolts, and take out the valve plate and the valve cover together. Removal of slotted round nuts, switch pins, hexagonal screws, front and rear stop caps, the cylindrical valve plate can be replaced, and the valve seat can be replaced at the same time. When cleaning the valve cavity, pay special attention to the sealing surface. To replace the new valve plate and valve seat, the gap between the valve plate and the valve cover boss should be filled with sealing grease, and the inside of the upper cover should be filled with calcium-based smooth oil to smooth the bearing. 2. Replace the lip-shaped packing: first remove the pressure in the valve chamber, then disassemble the guard, round nut, handwheel, bearing gland, bearing, packing gland, and then replace the lip-shaped packing. 3. Replace the bearing: Disassemble the guard, round nut, hand wheel, and bearing gland, and then replace the bearing. If you want to replace the lower bearing, you need to remove the stem nut. The bearing gap is adjusted by the bearing cover. After...

Crawler Type Core Drilling Rig Machine

December 09 , 2022

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 functional components such as slewing mechanism, feeding mechanism, lifting platform mechanism, transmission design mechanism, control working device and base. Depending on the type of drilling rig, some core drilling rigs may also need to be equipped with supervisory control and measurement analysis instruments or other related accessories. The rotating mechanism of the drilling rig is called the rotor, which is used to drive the drilling tool to rotate, so that the drill bit can continuously break the rock. There are three types of drilling rigs: vertical axis type, rotary type and mobile type learning through...
