1) gas break through prevention
气窜预防
2) anti-gas channeling
防气窜
1.
Based on the close packing and grain composition theory, a new anti-gas channeling lightweight high performance cement slurry system has been developed with industrial drift beads as lightweight additive and superfine gel as strengthening agent.
基于紧密堆积和颗粒级配理论,研制了一种以工业漂珠为减轻剂、以超细胶凝材料为增强剂的新型低密度、高强度防气窜水泥浆体系。
3) Anti-channeling
防气窜
1.
The Study of Anti-channeling Cementing Slurry in Puguang Gasfield;
普光气田防气窜固井液试验研究
2.
A new type of non-permeable latex anti-channeling slurry system can be used.
针对川东北地区高温、高压、高含硫气井主要固井技术难题,提出利用新型非渗透和胶乳防气窜水泥浆凝固后水泥石低渗透的特点,降低CO2和H2S对水泥石的腐蚀;固井前强化钻井液堵漏,提高地层承压能力;在固井时,采用纤维堵漏水泥浆;在固井前采用分段压稳设计模型,考虑固井后水泥浆失重的影响,分析固井后环空压力分布,保证压稳气层;固井水泥浆采用双凝或多凝设计,确保主力气层快速形成早期强度,实现"以快制气",有效控制气层气体。
