摘要
珠江口盆地文昌9-2/9-3/10-3气田属于低孔低渗储层,在分析射孔技术难点的基础上,对该气田各井进行了射孔方案选择和射孔段划分,确定了长夹层射孔采用多级增压起爆的射孔方式,并针对气田储层特征对射孔枪型、孔深、孔密和枪弹组合进行了优化。该射孔工艺与管柱安全分析研究对文昌三个气田的开发提供了具体的施工方案选择和安全优化,对南海西部类似气田射孔方案选择提供了基础。
the pearl river mouth basin,wenchang 9-2/9-3/10-3 gas field belongs to low porosity low permeability reservoir,based on the analysis on the basis of perforating technology difficulty,was carried out on the field the well perforation scheme selection and differentiate perforated interval,determines the long sandwich perforation using multistage charging detonation way of perforation,and in view of the gas reservoir characteristics of perforating gun type,hole depth,since this and bullets combination is optimized. The perforation technology and string safety analysis research of wenchang three gas field development provides the concrete construction scheme selection and safety optimization,similar to the west of the south China sea gas field perforating plan selection provides the basis.
