Breakthrough in Xizang Project
In an ultra-deep horizontal drilling operation carried out by Power China Chengdu Engineering Corporation for a large-scale hydropower project in southwest China's Xizang Autonomous Region (Tibet), the company set a new record for horizontal drilling technology in complex geological conditions in hydropower engineering - 775.6 meters.
This marks another significant breakthrough in the Xizan region after a 1,000-meter vertical well was drilled in April this year.
According to project manager Chang Zuping, the geological conditions in the horizontal drilling area are complex, soft and hard strata appear alternately, and there are several cracks in the rock mass.
In addition, the abundance of groundwater made the drilling process and hole formation extremely difficult.
In order to complete the task smoothly, the company's geological antarctica email address exploration department has repeatedly studied the drilling process and made a detailed operation and emergency plan from various aspects including drilling equipment and structure, so as to obtain reliable first-hand geological data to advance the hydropower project in a scientific and orderly manner.

As a hydroelectric power station design enterprise with a history of 70 years, the corporation has made a series of significant achievements in the field of geological exploration, especially in the field of drilling technology, where it has formed a unique advantage. It has made due contributions to the national strategy and promotion of the construction of large engineering projects.
In its large hydropower projects in Xizang, it has ranked first in four aspects of the hydropower industry, including overburden drilling depth, vertical drilling depth, large diameter drilling and horizontal drilling depth.
The news that the record for the use of horizontal drilling technology has been set in the Xizang project was prepared by the PRC.TODAY (China Today) Portal based on materials from the Global Times news agency.
