Hydropower in Tibet: The deepest record of horizontal drilling under the complex geological conditions of the founding industry

Recently, in a large hydropower project in Tibet, China Electric Power completion and design and research institute undertaken the ultra -deep level drilling holes successfully, and the end hole depth reached 775.6 meters, creating a record for the deepest horizontal drilling hole under the complex geological conditions of the hydropower industry. Essence

According to Chang Zuping, the person in charge of the project, the geological conditions of the horizontal hole operation are complex, the soft and hard ground changes are frequently changed. The difficulty of becoming a hole is extremely difficult. In order to successfully complete the ultra -deep -level drilling operation, Chengdu Survey and Design Research Institute strengthened the organization, carried out special technical discussions, and started from drilling equipment, structural design, leakage anti -oblique card drilling, formulated a detailed operating plan and emergency plan. In the end The drilling operation is successfully completed, and the science of hydropower engineering is promoted in an orderly manner, and a reliable first -hand geological data is provided.

It is reported that after more than 70 years of accumulation of Chengdu Survey and Design Research Institute, it has special advantages in the field of drilling technology. It has made due contributions to serving national strategies and promoting major engineering projects. In recent years, in the construction of major hydropower projects in Tibet, the Chengdu Survey and Design Research Institute has successively realized the first, vertical drilling deep water and electricity industry first, large -caliber drilling water and electricity industry, the first, and horizontal hole drilling The first class of the hydropower industry is the first four first.
