Hunan Daily, October 8th (Reporter Wang Liang, Correspondent Zhou Jinyun) From October 2nd to 5th, Henggang's third-generation special casing was successfully lowered into the first "ten thousand meter deep well" in the country, CNPC Tarim Oilfield's Deep Taco 1 well, setting a record for the deepest casing of the same specification in China.

Deep Tako 1 well was drilled on May 30th in the hinterland of the Taklamakan Desert, honking its horn. The designed depth of the well is 11100 meters, with an estimated drilling period of 457 days. It is a landmark project of the national implementation of the "Deep Ground Project".

The underground rock layers of this well are complex and need to penetrate more than 10 sets of layers from top to bottom. The project construction faces difficulties such as ultra-deep, ultra-high temperature, ultra-high pressure, overweight load, high stress, etc., and the performance and quality requirements for steel pipes are extremely strict.

Henggang actively participated in the project, and technical personnel optimized the design from the material and buckle type, using high-strength and high toughness materials and ultra-high sealing performance airtight buckles to ensure that the bearing capacity of the casing exceeds the actual usage requirements by more than 30%.

During the Mid Autumn Festival and National Day holidays, Henggang's technical and sales personnel came to the site to provide follow-up services, helping all casings successfully run into the well at once. The operator of the drilling team provided feedback that the casing produced by Henggang is easy to buckle and thread tolerance is well matched, and the one-time pass rate of the buckle is 100%.
