文13块是中原油田勘探开发的重点。针对该区块井深,油气分散,温度、压力高,注水开发水泥封固段内形成多套压力系统,盐层干扰厉害等因素严重影响固井质量的提高。通过提高顶替效率,优化水泥浆配方,强化固井工艺措施和使用双膨胀水泥浆体系,成功解决了固井后油气水窜槽和第二界面胶结质量差的问题,为今后同类井的固井提供了借鉴依据。 Article 13 is the focus of exploration and development of Zhongyuan Oilfield. In view of the well depth, oil and gas dispersion, high temperature and pressure in the block, several pressure systems are formed in the cement sealing section of water injection development, and the salt layer interference is severe and other factors seriously affect the cementing quality improvement. By improving displacement efficiency, optimizing cement slurry formulation, cementing process and double-expansion cement slurry system, the cementing quality of oil-gas water channeling channel and second interface after cementing has been successfully solved. Provided a reference basis.
