研发的封堵性固井减轻剂，所配置的低密度水泥浆具有密度低、强度高、自堵漏

The developed plugging cementing reducer, the low-density cement slurry is equipped with the characteristics of low density, high strength, and good self-plugging effect. It effectively solves the problem of low-pressure and easy-to-leakage block cementing slurry return height and upper part The problem of poor cementing quality in the well section.

The sealing cementing relief agent developed and configured with low density cement slurry has the characteristics of low density, high strength and good self-blocking effect, and effectively solves the problem of low pressure leak-prone block cement slurry return to high and poor quality in the upper well section.
