Drilling Of Water Wells. Types Of Wells
Wells, which are revealing layers and which contain groundwater have many advantages over other intakes, and for this reason their drilling is popular among the masses.
There are single holes or groups of wells for water extraction. Therefore, all water intakes from groundwater are divided into group and single.
Group ground water intakes consist of several simultaneously operating wells located at a distance at which they interact or may interact in certain conditions with operating mode.
Single subterranean water intakes are few wells and a group of wells that are outside the area of possible interactions or are even at a short distance from one another, but work at different times and therefore do not interact (in turn is only one borehole, and the rest are reserve holes).
In areas of large intakes of poorly known areas it is worth to conduct exploratory drilling and pilot work. In areas with the well explored hydrogeological conditions at the sites, where quality and quantity of groundwater responds to the projected demand it may be appropriate to begin immediate operational exploration wells of large diameter without prior intelligence. Once these wells will fulfill their purpose – the exploration and testing of the aquifer, they will be equipped with operational facilities and turned into permanent sources of water.
Single drilled wells for water are usually done without prior survey. Consequently, it is an original and important work, as well as exploration and investigation in this case must be combined with the creation of operational engineering structures.
Exploratory well is operational well, construction of which, including the intake part, is designed for equipment receiving water of project performance. These wells are transferred to the regular operation after the positive results of testing.
Pioneer well is a well of lightweight design and a relatively small diameter, equipped with a temporary filter and which is designed for discover and preliminary testing of the aquifer. Pioneer wells are usually facilitated in such a way for the drillers could remove the protective tube and filter.
Operational well can be considered a well after its transfer into operation. This name should not be attributed to well at design, because even in areas with well-studied, but not explored in detail geological and hydrogeological conditions there could be are always found significant deviations from the project. For this reason, the single hole on water, which is drilled without prior survey of point of inception, must always be of pioneer designation. In the project design of almost every hole gets changes during the process of drilling, testing and equipping. This is the fundamental difference between the purpose and objectives of the utilization drilling for water from drilling of such wells as oil wells.
No doubt water has an important place in our lives. In many cases people want to have an independent or alternative water supply source.
