After more than 70 days, the emergency operations of drought prevention, water and well drilling in Shandong, Hebei, Henan and Shanxi provinces exceeded the planned tasks and achieved fruitful results. This is what the reporter learned from the summary and commendation meeting on the work of drought relief and water drilling in the four northern provinces of the land and resources system held on April 28. According to reports, the working area of ​​drought-resistant water-seeking wells in the four northern provinces is about 200,000 square kilometers. At present, the four provinces have completed 2,349 exploration drilling holes with a completion rate of 111%. The total drilling depth of the four provinces is more than 333,000 meters, the wells are 2,227 eyes, the average well formation rate is 94.7%, and the total water output is about 1.165 million cubic meters per day. More than 2.2 million people have difficulty drinking water and 500,000 mu of farmland irrigation, which also provides security for the long-term living of people in water-scarce areas. At the same time, the large amount of wellbore data and geophysical data obtained in this work provide basic data for the development and utilization of groundwater resources in the future, and respond to similar extreme arid climates and emergency water supply. The central bank's interest rate rises to indicate a rate hike Scientific and technological progress is an important factor in the fruitful results of this work. The hydrogeological survey results of the in-situ mining department for decades and the 12-year geological survey of the Ministry of Land and Resources have provided a large amount of basic data for drilling wells, and compiled four types of 42 drought-resistant well-drilling technical service maps, which are conducive to rapid Determine the water and well drilling target area; the geological exploration unit participating in the drought relief has selected a team of experts and equipped with advanced equipment to lay the foundation for the scientific selection of well locations; drilling technology with deep hole drilling and high pressure and high air volume The machine-based drilling technology and drilling technology combined with impact drilling and rotary drilling provide technical and equipment support for fast drilling and high quality well formation. In addition, strict technical management ensures the quality of the project.
