The company’s independently developed lightweight material has a compressive strength of up to 60 MPa.
Summary：For Well Renhe 1, a 273.1-mm casing was cemented using a cement slurry with a density of 1.45 g/cm³. The slurry incorporated a lightweight material developed in-house by our company. After subjecting the slurry to a pressure of 60 MPa, its density changed to 1.45/1.46. This lightweight material boasts low cost and excellent performance, making it highly significant for reducing the cost of low-density cementing operations in deep wells.

Good News: Sinopec Achieves New Breakthrough in “Deep-Earth Engineering”
Recently, Sinopec’s “Deep-Earth Engineering–Sichuan–Chongqing Natural Gas Base” has once again reported a significant breakthrough. The Yonghong-1 well, a key ultra-deep tight sandstone exploration well deployed by Sinopec Exploration Branch in Bazhong City, Sichuan Province, has successfully tested high-producing gas flows, marking an important new stratigraphic breakthrough in the Jurassic system of the Sichuan Basin. This discovery confirms the favorable exploration and development potential of the Jurassic tight sandstones in the Bazhong area, suggesting the prospect of establishing a new resource base for increasing reserves and boosting production in the Sichuan Basin.
