中原油田水平井固井技术

The Cementing Technology of Horizontal Well in Zhongyuan Oilfield

根据中原油田地质特征 ,结合国内外水平井固井技术发展状况 ,从优化钻井设计、井眼清洗、套管扶正居中、液体流态、冲洗隔离液及水泥浆性能方面提出了提高水平井顶替效率和固井质量的技术措施。通过 4口井的实际应用 ,取得了较好的固井质量。

According to the geologic characteristic of Zhongyuan oilfield, combined with the development situation of horizontal well technology in home and abroad, this paper presents the technical measures about how to enhance displacing efficiency and cementing quality from optimizing drilling program design, bore hole cleaning, casing centralization and positioning, fluid flow pattern, flushing spacer and cement slurry properties Through four wells’ application, the cementing quality has achieved better results, and provides better reference substance for the future horizontal cementing jobs
