低摩阻低密度水泥浆体系研究

Well Cementing with Low Friction Pressure Resistant Leaking Preventive Low Density Cement Slurry

针对承压能力相对较低地层固井质量差的问题,本次研究首先对低密度水泥浆四级颗粒级配开展设计,对颗粒级配材料进行合理的优选和配比,开展低摩阻耐压防漏低密度水泥浆配方形成与性能评价研究,为形成低摩阻耐压防漏低密度水泥浆固井技术奠定基础。

In response to the problem of poor cementing quality in formations with relatively low pressure bearing capacity,the fourth grade particle grading of low density cement slurry was designed firtsly,the particle grading materials was optimized and proportioned reasonably,and the research was conducted on the formation and performance evaluation of low friction,pressure,and leak proof low density cement slurry formula,laying the foundation for the formation of low friction,pressure,and leak proof low density cement slurry cementing technology.
