摘要
近20多年来,深水海域的油气勘探和开发变得越来越重要。本文讨论了深水固井中存在的问题:固井温度一般比较低;地层孔隙压力和破裂梯度之间的窗口比较窄,地层易漏;容易发生水、气窜等。介绍了目前国内外常用的几种深水固井水泥浆技术:水泥粒径优化技术、高铝水泥浆技术、快凝石膏水泥浆技术和泡沫水泥浆技术。图3表1参8。
In the recent 20 years, the oil and gas exploration and development in deep water areas become more and more important. The problems encountered in deepwater well cementing are low temperatures of boreholes, narrow gap between pore and fracturing pressures in formations, high susceptibility to fluid intrusion, and creation of interzonal channeUings. Several cement slurries for deepwater wells developed abroad and in China are presented and these are： slurries of cement with optimized particle size distribution, high aluminous cement slurries, quick setting gypsum slurries, and foamed cement slurries.
