摘要
川西蓬莱镇组气藏为致密砂岩气藏,储量丰富,一般采用水平井开发技术。针对前期水平井固井质量不理想的现状,对一系列固井技术难点展开研究,提出了相应的改进方案:清除沉床岩屑,提高注水泥顶替效率(包括清油效率),优化水泥浆性能,从而为提高水平井固井质量提供了可靠的保证。
In western Sichuan Basin,Penglaizhen Formation is tight sandstone gas reservoir with abundant reserves. Horizontal- well technology is generally adopted in its development. But,cementing quality is not well during the early stage. So,this paper studies a series of cementing difficulties,and proposes some corresponding solutions,such as cuttings removal,increasing slurry displacement efficiency( including oil removal efficiency),and optimizing slurry performance. Those provide a reliable guarantee for improving the cementing quality of horizontal well.
