Why choose DTH Hammer drilling way for water well drilling work

June 01 , 2022

The birth and development of the pneumatic water well drilling rig is a large revolution in drilling technology. It changed the traditional way of cutting and grinding rock, breaking the rock into volume, greatly improving drilling efficiency and adaptability to hard and complex formations. Its remarkable technology Economic benefits are regarded as one of the symbols of modern drilling technology and measurement of drilling technology, and are valued by the drilling industry at home and abroad. Pneumatic DTH hammer drilling mainly begins with drilling blasting holes, well bedrock holes and geological exploration holes. In order to expand its application scope, domestic and foreign researchers, such as working performance of the DTH hammer, make it suitable for various projects , different application requirements.

Classification of water well drilling rigs　(I)

May 28 , 2022

Classification of water well drilling rigs　(I) Water wells are generally divided into three categories: water supply tube wells, large wells and radiation wells. Generally, the well is deeper and the diameter is relatively large, and the well composed of wellhead, well wall tube, aquifer section and necessary filters is called tube well; wells with a diameter greater than 2m are collectively called large wells; A large diameter catchment well The water intake system composed of several to dozens of horizontal radiant tubes with a certain length of multi-layer and several to dozens of horizontal radiant tubes driven into different directions from the water collection well is called a radiant well.

Methods of Hydrological Logging 3

May 20 , 2022

Hydrological logging There are many kinds of geophysical logging methods. Commonly used hydrological logging methods mainly include natural electric field method, resistivity method, natural gamma method, and acoustic wave method. Both the natural electric field method and the resistivity method belong to electrical logging, which is commonly known as electrical logging. The drilling rig is mainly used to determine the location and thickness of the aquifer, divide the interface between salty and fresh water, and estimate the The water quality and quantity after the well is completed. When exploiting deep fresh water, electrical logging can provide a reliable technical basis for the design of the well pipe structure and the determination of the sealing depth of the salt water layer.

Hydrological logging is an important part of groundwater exploration. Through logging, we can further understand the properties and conditions of aquifers, obtain the location and thickness of underground aquifers, accurately divide the interface between salt and fresh water, and obtain the water content of each aquifer. The results are not only of great significance for guiding the well formation, but also an important reference for groundwater resource evaluation.

Classification of Mud Pumps

May 18 , 2022

There are many types of mud pumps, and the classification methods are also different. Generally speaking, there are the following types: (1) According to the number of cylinders, it is divided into double-cylinder pumps, triple-cylinder pumps, etc. (2) According to the number of times a piston inhales or discharges liquid once in the liquid cylinder, the one that suctions or discharges liquid once is called a single-acting pump, and the one that suctions or discharges liquid twice is called a double-acting pump. (3) According to the arrangement and mutual position of the liquid cylinders, there are horizontal pumps, vertical pumps, V-shaped pumps and star pumps. (4) According to the piston style, it is divided into piston pump, plunger pump, etc. Since the liquid transported by the mud pump is usually drilling fluid, it is customarily called the mud pump as the drilling pump.

Methods of Hydrological Logging

May 12 , 2022

Hydrological logging is that after the drilling machine completes the wellbore, the logging probe is placed in the well with a cable, and the physical property difference of the rock formation at different depths is measured by the surface instruments and equipment, and the lithology and water quality of the wellbore are analyzed according to the site survey results. In this case, this method is called hydrological logging.
