泡沫钻井在大牛地气田盒1气层的应用

Application of Foam Drilling in He 1 Gas Layer of Daniudi Gas Field

为有效解放气层,且对应用欠平衡技术开发大牛地气田盒1气藏进行经济技术评价,在盒1气层开展了氮气泡沫欠平衡钻井试验,实现了全过程欠平衡,有效保护了储层,机械钻速较常规水平井大幅度提高,为大牛地低渗气田的开发提供了技术储备。

Nitrogion foam under-balanced drilling test was made to effectively release gas reservoir and evaluate the technical and economic feasibility of under-balanced horizontal well in developing He 1 gas reservoir of Daniude gas field,whole process under-balanced was realized to protect the gas reservoir with higher penetration rate than common horizontal well drilling.It provides the technical reserve for the development of Daniudi low permeability gas field.
