Ultra-high-density latex cement slurry system successfully implemented.

On December 12, 2013, our company’s independently developed ultra-high-density (2.80 g/cm³) latex-based cement slurry for preventing channeling was successfully applied in the cementing operation of the Φ244.5 mm casing at Well Wen72-421 in the Zhongyuan Oilfield. The construction process went smoothly, the slurry exhibited excellent fluidity, and the cement slurry density was uniform (with a maximum density of 2.82 g/cm³), resulting in high-quality cementing results.

Hongsheng Company Successfully Completes Pilot Production of Temperature- and Salt-Resistant Fluid Loss Additive

The quaternary copolymer oil-well cement fluid-loss additive, independently developed and produced by Hongsheng Petroleum Technology, has successfully passed both laboratory testing and field applications. This novel fluid-loss additive, copolymerized from AMPS, AM, AA, and N-vinylpyrrolidone, exhibits remarkable resistance to temperature and salinity, meeting the stringent requirements for cementing operations in high-temperature and high-salinity environments.

The company’s latex-based cement slurry system for preventing gas migration ensures that both laboratory and field preparation times are reduced to 7.

Well Yuanba 103H was cemented using 193.7 mm casing, with a well depth of 7,045 m and a cementing interval of 2,400 m. The well’s inclination was 85.5 degrees. After two months of preparation for experiments by a well-known foreign company failed to meet the required standards, our company’s latex-based cement slurry system for preventing gas migration was adopted. As a result, the time required for deep-well reservoir cementing experiments and on-site preparations was reduced to just 7 days, and the cementing operation proceeded smoothly with qualified cementing quality.

The company’s independently developed lightweight material has a compressive strength of up to 60 MPa.

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.
