摘要
通过对川东北海相地层地质特点研究和固井质量统计,总结了研究区固井工艺难点;在此基础上,提出了针对高温、高压井的固井改进工艺。该工艺已运用于川东北地区,并取得了良好的效果,大大提高了固井合格率和优良率。
Based on the study of seological characteristics of marine strata in northeast Sichuan and the statistics of cementing quality, the difficulties for cementing technology of study area are summarized. And improved cementing technology for high temperature and high pressure well are presented. The technology has been applied in northeast Sichuan with good effect, which increased qualification rate and excellent rate of cementing greatly.
