多凝水泥浆体系在LD气田的应用

Application of multi-setting cement slurry system in LD gas field

采用多凝水泥固井技术,在一定程度上可以代替双级固井,具有极大的优势。根据不同的井下条件采用针对性的水泥浆配方,可以防气窜、防漏失、防套管腐蚀、防施工高压、降低固井成本,并能高效地保护油气层,提高固井质量。

Multi-setting cement slurry system has great advantages and can be used to replace the double stage cementing to a certain extent. Different cement slurry formula is adopted according to the conditions of downhole to avoid gas channeling,leakage,casing corrosion,and construction of high pressure. It can reduce the costs of cementing,improve the cementing quality,and effectively protect the reservoir.
