How to choose the right water well drilling rig?

March 27 , 2024

When selecting a suitable water well drilling rig, simple configuration, low energy consumption, easy operation, high maneuverability, high versatility and small size are usually required. In actual operation, the appropriate drilling rig type needs to be selected based on factors such as formation conditions, borehole size, drilling depth, and drilling methods. 1. Drilling efficiency: Drilling efficiency is affected by many factors such as formation conditions, operator skills/experience, drilling rig type and drilling methods. When rock conditions are applicable, it is recommended to use an underground drilling rig with an air compressor; for soil, clay and sand conditions, the best option is to use a drilling rig with a mud pump; while in conditions such as cobblestone, a reverse circulation system is the most suitable drilling method . 2. Price: The price of the machine is a key factor in choosing a suitable drilling rig, and it is also a one-time investment. As the borehole diameter and depth increase, so does the machine price. Comparing different drilling rig types, the price of down-the-hole drilling rigs is higher than that of core drilling rigs, and the price of hydraulic drilling rigs is higher than that of vertical shaft drilling rigs. In addition,...

What should be done before using the drilling rig?

March 18 , 2024

What should be done before using the drilling rig? 1. Mechanical part inspection Check the appearance of the machine, including whether the body, tires, frame, glass and other parts are damaged or dirty. Check whether the engine parts are normal, such as water tank, air filter, oil level, belt tightness, etc. Check whether the steering system and tachometer operate normally and whether there are any abnormal noises. Check whether the bearings, switches, steering gear, oil pipes and other components are tight and whether they are loose or worn. 2. Hydraulic system inspection 1. Check whether the hydraulic oil is sufficient. If it is lower than the standard liquid level, you must add hydraulic oil. 2. Check the quality of the hydraulic oil. If turbidity or blackening is found, the hydraulic oil must be replaced. 3. Check whether the hydraulic system pipelines, air pipes, hydraulic pipelines, hoses and other parts are aged or damaged.

The Principles of the Wireline Core Drilling Rig

March 06 , 2024

The core taking principles of the rope core drilling rig mainly include the following aspects: Drill pipe and drill bit: Drill pipe is a hollow rod made of high-strength steel with a hollow interior. The drill bit is a key component of a wireline coring drill. It is usually made of rigid material and is used to break and mill formation rocks. Rope: The rope is an important part of the rope coring drill. Its function is to drag the drill bit underground and connect it to the drill pipe. The rope will reciprocate back and forth between the landing wheel at the drilling wellhead and the top winch to complete the coring effect. Overshot: After drilling a certain amount of footage that does not exceed the length of the inner core tube, stop the pump and stop drilling. Use a thin wire rope to lower the overshot from the drill pipe from the ground, reach the bottom of the hole, grab the overshot head of the inner core tube, and then lift it up. Disengage the bayonet to separate the inner and outer core tubes, lift the inner core tube from the drill pipe to the ground, and take...

How does a water well drilling rig work?

February 27 , 2024

The working principle of a water well drilling rig is to use the power of a diesel engine or electric motor to rotate the drill pipe and drill bit to cut underground rocks or soil and gradually dig out the water well tunnel. Water well drilling rig consists of drill pipe and drill bit, drilling rig, conveying system and control system. The drill pipe is the part that connects the drilling rig and the drill bit. It is usually composed of steel pipes and is used to transmit rotational force and withstand the vibration of the drill bit. The drill bit is the part used for cutting and breaking underground rocks or soil. It is usually made of steel, and its shape and structure vary according to different geotechnical conditions. The water well drilling rig is the core part of the entire water well drilling equipment. It can provide power to drive the drill pipe and drill bit to rotate and press down. The delivery system includes water pumps and delivery pipes, which are used to inject water or air into the borehole and discharge the cuttings out of the wellhead. Water well drilling equipment is usually equipped with a...

What are the common faults of pneumatic water well drilling rigs? How to solve?

February 06 , 2024

Common faults generally include stuck drill, invalid drill rod or drill bit, inability to remove chips, and fatigue in the drill. The processing method is as follows: 1. Drill stuck During operation, some sand, steel bars, casings, small components, etc. accidentally enter the well or penetrate deep into the drilling tool, which can cause the drill to get stuck. The solution is also very simple, that is, cleaning. 2. The drill rod or drill bit is invalid It should be due to operation and co-movement that the drill rod or drill bit is invalid and the engineering drilling rig cannot operate normally. The best solution is to replace it. 3. Unable to remove chips Some types of drilling rigs in engineering drilling rigs have poor chip removal effect, so it is easy to cause chip discharge blockage. The solution is to dredge it, but the best preventive effect is to increase the air volume. 4. Drilling rig is weak There are many factors that cause fatigue in the drilling rig. If it is pneumatic, it may be insufficient air pressure. There are many reasons for insufficient air pressure, which need to be investigated and repaired. For hydraulic rigs, it is...
