A well screen is a filter device used as the suction portion of a well constructed in a loose or semi-consolidated aquifer. The screen allows water to enter the well from the saturated aquifer, prevents sediment from entering the well, and acts structurally as a support for the aquifer material. When considering well efficiency and the logarithmic cost to the well owner, the importance of having the right screen cannot be overemphasized.
The sieve is resistant to corrosion because it comes into contact with water. In addition, it has high strength and can keep the surrounding structure intact. The openings of the sieve can be small enough to block the large amount of formation around them. The flow of water through the screen will be uniform.
Well screens are recommended for all environmental drilling operations. It helps extend the life of the well and keeps the flow of water unrestricted. Sand and fine powder sand, these fine particles can be filtered out before there is water. Well screens help remove most of this fine material from well water.
Well screens are made from a variety of materials, ranging from rough-hewed hand designs to machine built high-efficiency and long-life models. The value of the screen depends on how much it contributes to the success of the well.
Standard:
- Large open Spaces
- Do not block the slot
- 3.corrosion resistance
- Sufficient column and collapse strength
Functions:
- Easy to develop
- Minimal scaling tendency
- Low head loss through the screen
- Control sand pumping of all types of aquifers
Slot size selection is a critical step to ensure maximum well performance. The screen is usually designed to block 50% of the stratum, and the entry speed for the screen should not exceed 1/10 or 0.1 ft per second. The velocity is calculated by dividing the well production in GPM by the screen open area in square inches.
The gap size of the screen is based on dimensional analysis of the formation sample. After analyzing the composition size of grain in the sample, grain size distribution curve
I can draw it. Several methods can be used to obtain the allocation of information about grain size. The most widely used method is to pass the material through a stacked set of brass or stainless steel sieves. During the screening process, each sieve removes a certain percentage of the whole sample; The best materials are collected in the chassis. Screening analysis not only provides the basis for determining slot sizes, but also other factors that influence screening well design.
