In the process of water well drilling, accurately determining whether the drill has reached the water - bearing layer is crucial, as it directly affects the progress and cost of the drilling project. As a professional manufacturer of water well drilling rigs, UNIQUE is well aware of the importance of this judgment. Here, we will introduce several practical methods to help you accurately determine if you have drilled into the water - bearing layer during the drilling process.​

1. Measuring Well Depth​

During the drilling process, when the drill pipe is descending, it will transmit a signal to the drilling rig. When the magnitude and frequency of this signal change, it may indicate that the stratum has changed, and it is likely that the water - bearing layer has been reached. At this time, you can make a judgment by observing the well depth measuring instrument.​

When observing the well depth measuring instrument, it is important to pay attention to the calibration of the instrument to ensure the accuracy of the data. At the same time, by combining with the change law of the signal transmitted by the drill pipe, you can more accurately judge whether the stratum has changed and whether the water - bearing layer has been reached. UNIQUE water well drilling rigs are equipped with high - precision well depth measuring instruments, which can better capture the signal changes transmitted by the drill pipe, providing a more reliable basis for judging the water - bearing layer.​

2. Measuring Seepage Flow​

When drilling reaches a potential area with a large water content, data can be obtained through a seepage flow meter. When water enters the well, it will generate pressure, which is transmitted to the seepage flow meter through a pipeline, and at this time, it can be judged whether the water - bearing layer has been drilled.​

The installation position of the seepage flow meter should be reasonable to ensure that it can accurately receive the pressure signal. After obtaining the data, it should be compared and analyzed with the geological data of the area to more reliably judge whether the water - bearing layer has been drilled. UNIQUE water well drilling rigs can be perfectly matched with various seepage flow meters, ensuring the smooth transmission of pressure signals and improving the accuracy of data acquisition.​

3. Water Level Gauge Detection​

A special instrument, the water level gauge, can be placed at the bottom of the well to monitor the water level height in real - time. When water seeps out of the rock crevices and reaches the bottom of the well, the water level gauge will display a higher water level data within a certain period of time, and through this data, it can be judged whether the water - bearing layer has been drilled.​

When placing the water level gauge, ensure that it can be stably placed at the bottom of the well to avoid displacement due to vibration during the drilling process. When monitoring the water level data in real - time, record the change trend of the data. When a continuously high water level appears, comprehensively judge whether the water - bearing layer has been drilled in combination with the geological conditions. UNIQUE provides high - quality water level gauges that are stable and reliable, ensuring accurate monitoring of water levels.​

4. Direct Observation​

During the drilling process, if the drill cuttings show obvious changes in color, transparency, including sediment, granularity, etc., it may indicate that the water - bearing layer has been drilled, which can be judged by direct observation.​

When observing the drill cuttings, regularly sample and analyze the drill cuttings, and compare the characteristics of drill cuttings at different depths. When it is found that the color, transparency, etc. of the drill cuttings have obvious changes and meet the characteristics of the drill cuttings in the water - bearing layer, further confirmation should be made by combining with other methods. UNIQUE water well drilling rigs have a reasonable design, which is convenient for operators to observe the drill cuttings at any time.​

In conclusion, the methods of well depth measurement, seepage flow measurement, water level gauge detection and direct observation can be used to judge whether the drilling has reached the water - bearing layer. In the actual operation process, a reasonable choice can be made according to the geological conditions of the drilling area and the logging analysis to determine the depth of the water - bearing layer.​
