摘　　要：针对YZ-2HF井二开龙马溪组地层承压能力弱、易漏易垮,井径不规则度大等问题,设计双凝双密度水泥浆体系固井,通过加重型防漏前置液体系、扶正器安放及钻井液性能、施工参数的优化,提高环空钻井液顶替效率和界面肢结质量,形成一套适合YZ-2HF井技术套管固井技术,可为同区块技术套管施工提供技术经验。Aimed at such challenges as weak pressure-bearing capacity,vulnerability to leakage and collapse,large borehole rugosity and others in the zones of the Longmaxi Formation during the second spud in Well YZ-2HF,the separable setting and double density cement slurry system is applied to improve the displacement efficiency of annular drilling fluid and interface cementation quality by adding weighted leakage-proof pre-pad fluid system and by optimization of centralizer placement,drilling fluid performance and operation parameters,such that a set of casing cementing technology for Well YZ-2HF is established to provide technical experience for the cementing jobs in the in-termediate casing of the same block.
