What Are The Folk Methods Of Digging Wells For Water

In our shandong province jining city in the countryside still have the habit of drilling Wells, but drilling Wells often dozen meters but no water, this is a waste of money and energy, so how to judge underground water? In fact, there have been many ways to judge.

It is generally believed that drilling a well is "drilling a hole and lowering a root canal", which seems simple but has a high technical content. It involves hydrogeology, geophysical prospecting for water, well formation technology, pump selection and other aspects of knowledge, which is often not paid attention to, and is prone to failure, poor quality and high risk. Although the knowledge of digging Wells to find water is very deep, but if the parties master some scientific knowledge, reduce blindness, or very useful.

Local hydrogeological conditions should be studied in detail. If you do not understand the hydrogeology, do not study the hydrogeology conditions, only believe in the instruments, everywhere random measuring points, can only be called "blind test." The research can be carried out from the following three aspects.

Study topography. Topographic and geomorphic conditions determine the recharge and discharge conditions of groundwater, control the weathering status of rocks and affect the changes of groundwater abundance and depletion. It is the same to build a reservoir with a drainage area, and to dig a well with a recharge area.

If the lithological conditions are the same, low-lying or conducive to water catchment topography is more likely to well. However, some small plains and depressions tend to be dominated by argillaceous rocks, which are easy to be eroded by weathering to form lowlands, and the groundwater is not good.

Study the water richness of rocks. Rocks can be divided into igneous rocks, metamorphic rocks and sedimentary rocks according to their genesis. Whatever the cause, the feeling of hammtering on a rock can be "gen" (rigid), "spongy" (flexible), and "brittle" (brittle). Soluble rocks such as brittle rocks and limestone are more likely to produce Wells.

Shandong China Coal Group geological exploration equipment research institute since its establishment, adhere to the "science and technology, talent strong school" strategic objectives, invested tens of millions of scientific research funds, in the natural electric field of geophysical exploration equipment research and development, urban water supply pipe network loss reduction equipment research and development, the development and utilization of water resources, geological disaster monitoring, etc to strengthen the construction of talent team and new product research and development of new technology, was awarded a number of patents, developed with independent intellectual property rights of leakage detection and geological prospecting and other professional software and equipment.

At present, our group mainly focuses on r&d and manufacturing products:

On-board pressure pipeline loss reduction system; Pipeline loss troubleshooting system, pipeline leak tester, pressure pipeline leakage automatic analyzer; Vehicle-mounted geophysical prospecting system; Geophysical water finder, cavitation detector, prospector, dyke surge detector, natural disaster monitoring system, geological environment monitoring system.

.

The products are mainly used in the leak-proof test of civil well drilling and water search, government agency urban pipeline (water network, natural gas network); Natural disaster monitoring, early warning and protection. Mineral exploration, urban road void detection. Levee safety inspection.
