Guizhou Geological Bureau 1000-meter deep well water level monitoring

Case Description

Specific Requirements: Guizhou Provincial Geological Survey 111 Geological Team

Operating Environment: Yuhongxia Geothermal Water Extraction Test, deep well depth 1000 meters, water temperature below 90℃.

Monitoring Requirements: Real-time display of deep well water level during the water extraction test to provide a basis for calculating geothermal resource exploitation; automated monitoring to improve office efficiency and reduce labor input;

Ensure data accuracy, timeliness, and effectiveness;

Ensure long-term operation underwater at 1000 meters and below 90℃.

II. Needs Analysis

Deep well water level monitoring, due to its special measurement characteristics, non-contact methods such as radar level meters and ultrasonic level meters cannot effectively transmit signals, magnetic level indicators and bubble type level meters cannot achieve such a deep measuring range. Now, the WH311 deep well dedicated level sensor probe provides intuitive and clear continuous level monitoring with high accuracy, greatly simplifying the measurement process and reducing the cost of on-site data acquisition. It is especially suitable for deep well water level measurement and monitoring, meeting the following user needs:

1. The WH311 deep well sensor probe features an all-welded integral structure design, ensuring normal operation underwater at 1000 meters, and passing a 20MPa waterproof test (equivalent to 2000 meters underwater waterproofing);

2. The signal transmission uses high-strength polyurethane-grade steel wire cables (during placement, be sure to pay attention to cable protection), ensuring real-time, high-precision, and stable output of the measurement signals;

3. Real-time display of deep well water level, with high and low level alarm functions, can be linked with deep well pumps to realize low-level pump stop function, preventing deep well pumps from running dry.

III. Scheme Design Diagram and Installation Instructions

*Groundwater automatic monitoring equipment and transmission system requirements
Install one set of groundwater automatic monitoring equipment, which can measure and record water level, water temperature, and other elements, and can automatically record data; the automatic recorder housing is made of stainless steel, with a simple structure and small size; the monitoring frequency is optional (1S-4 minutes), and the data storage capacity is not less than 200,000 entries; data can be directly exported in tabular format.
