Daqing Drilling Company No. 1 Well Bei 1HC Horizontal Section Cementing Quality Rate Hits A New High in Hailar Area

Daqing Drilling Company No. 1 announced on the 25th that the Bei 1HC well constructed by the company's 50066 drilling team was successfully completed, setting the best results in the Hailar area with a high-quality cementing rate of 99.8% in the open-hole section and a 100% high-quality cementing rate in the horizontal section.

In the Hailar area, the formation is prone to leakage, making it difficult to seal the entire well with original slurry, and the quality is difficult to guarantee. In this regard, Daqing Drilling Company No. 1 implemented "one well, one strategy" and held planning meetings with collaborators in a timely manner to ensure smooth completion of the well.
Well Bei 1HC is a key exploration well with a drilling depth of 3,339 meters and a horizontal section of 472 meters. The first drilling company adopted the concept of "big completion" and strictly implemented the integrated geological engineering plan. Experts stationed at the front line to track drilling progress and make preparations for well completion.

The staff of the 50066 drilling team checks whether the distribution box in the SCR room is working normally.

The completion cement slurry plan was determined based on the pressure test, and the completion plan was scientifically demonstrated. A full downhole casing plan was adopted, and the liner hanger was eliminated, which greatly saved costs, reduced the completion cycle by 10 days, and improved the completion time. It also improves the integrity of the casing string. At the same time, during the cementing construction process, the flow pattern and density of the cement slurry entering the well should be ensured, and the injection and displacement volume should be increased to improve the displacement efficiency.
