摘　　要：LD气田预探井具有一次封固段长、温差大、易漏失等难点。现场应用高强低密度水泥浆体系,控制不同阶段的施工排量等方法,解决了低压油气层长封固段防漏、防窜问题,固井质量满足了开发和油气层保护的要求。The pre exploratory well in LD gas field has faced many difficulties,such as long sealing time,large temperature difference and leakage.The high strength and low density cement slurry system was used and construction displacement at different stages was controlled to solve the leakage and channeling in long sealing section of low pressure reservoir,the cementing quality meet the requirements of reservoir protection and development.

关 键 词：长封固段 低密度水泥浆 一次上返 防漏
