前言随着我国石油勘探开发事业的发展,特别是海上石油勘探开发工作的兴起,钻遇地层条件日益复杂,采用纯水泥浆固井已不能适应和正确处理复杂的井遇条件。外加剂的加入,在固井水泥性能的改善,深井、超深井、特殊井、复杂井疑难固井工程问题的处理,油层产能的保护,采收率的提高,油井寿命的延长等方面带来了不可估最的效益。而原浆钻井、原水泥浆固井则效率低、事故多、质量差、寿命短,使潜在的产能被压抑、堵死,地下财富不能有效开采出来。
Preface With the development of petroleum exploration and development in our country, especially the rise of offshore oil exploration and development, the formation conditions of drilling are getting more and more complicated, cementing with pure water cement can not meet and correctly deal with complicated well conditions. The addition of admixture brings about the improvement of cementing performance, the treatment of deep well, ultra-deep well, special well, complicated well cementing engineering problems, the protection of reservoir productivity, the increase of oil recovery rate and the prolongation of the life of oil well Invaluable benefit. The original cement drilling, cementing the original cement slurry is inefficient, accidents, poor quality, short life expectancy, the potential production capacity is suppressed, blocked, underground wealth can not be effectively mined out.
