How to accurately find groundwater resources, is the problem of each well drilling people, who mastered the water finding skills, who will be able to seize the opportunity in the market, the following will give you a few experts easily not to pass on the water finding skills to help you out of the big water, make a lot of money.

As a groundwater source, in terms of hydrogeology, generally need to have two basic conditions.


1, to have a water storage structure.


2, to have a proper source of recharge.


A water storage structure is like a container, without which no water can be contained, and without which no groundwater can be stored. However, if there is only a storage structure without an appropriate source of recharge, then either there is no groundwater in the structure or the amount of groundwater is limited and cannot meet the application or create a valuable groundwater source.


The basic task of finding groundwater is to find the storage structure and to determine its recharge conditions, determine and infer its water quantity, level and quality based on the factors that control groundwater.


Storage structure plus other factors controlling groundwater, the problem is multifaceted, in the search for groundwater, in general, the following points should be considered in turn:


a. Clarify the requirements of the water source


Due to the different requirements of water quantity, water quality and water level, the storage structure and recharge conditions that need to be found are also different. So at the beginning of the work, the first thing to do is to clarify the task, to clarify the requirements of the use of the unit on the water source.


bUnderstanding the geological structure


The void of the rock is the place where the groundwater is stored, so in terms of hydrogeology, the lithology and geological structure of an area should first have a comprehensive understanding. There are many types of rocks, which can be broadly categorized into three types of rock formations: weakly permeable, permeable and strongly permeable.


In mountainous areas, topography controls the groundwater runoff conditions, and in plains, geomorphology controls the distribution of aquifers. Therefore, it is important to have a comprehensive analysis of the topography and geomorphology of an area.


Based on the understanding of lithology, geological structure, topography and geomorphology, combined with the outcropping and changes of springs and surface water, different hydrogeological units can be initially circled and further divided into groundwater recharge, runoff and drainage lots.


cSearch for water storage structure


On the basis of the above work, looking for the required water storage structure. Water storage structure is generally composed of a multi-gap rock layer conducive to groundwater collection, such as karsted limestone, multi-fractured sandstone, fracture fragmentation zone, flooded sand and pebble layer, alluvial sand and pebble layer, etc.. However, there are exceptions, such as mountainous areas composed mainly of limestone, where the limestone is highly permeable and the groundwater table is very deep, making it unsuitable for mining. In these places, it is necessary to look for weakly permeable strata, because the existence of these rock layers in the lot may keep some upper stagnant water.


dSelect water extraction lot


According to the distribution of water storage structure and the need of water, choose the water extraction lot. In the selected water extraction lot, you can further refer to some hydrogeological data of other similar areas and take the necessary exploration means to infer and determine the water quantity, water level and water quality of the water extraction lot according to the various factors controlling the groundwater.


eUse water detector


water detector

PQWT-TC series automatic map water detector is to earth electromagnetic field as the field source, based on the difference in electrical conductivity of different underground geological structures, through the measurement of different frequencies of the electric field components of the law of change, to study the geological structure and change, scientific search for groundwater resources geological structure changes through the curve display in real time. A simple one-click operation automatically generates geological profiles, getting rid of the tedious computer mapping. The instrument is widely used in different terrains such as plains, hills, mountains, plateaus and basins to quickly analyze the changes of geological structures and to determine the well location, aquifers and depth of aquifers.


Through comparative analysis of field work examples, the water detector can reflect the geological information in a certain depth range of the underground, and can be used for geological minerals, engineering physical exploration and rapid census of water resources.
