| 摘 要： | 难动用储量在油气资源中所占比例逐渐增大,且大都表现出储层层系多、间距小及物件条件差等特点.因此,分层压裂工艺成为此类油气藏投产、增产的主要方法.但目前分层压裂存在改造风险性高、难度大、增产效果不明显等难题.结合川西苏码头构造的气藏工程地质实际,分析码浅17-1井和码浅1井在分层压裂中存在的问题,提出了低渗透气藏分层改造关键技术对策.

| Abstract: | Difficult-to-produce reserves are increasing the proportion of oil and gas resources gradually,and mostly shows the reservoir of multi-layers,small spacing,worse physical conditions and so on.The separate layer fracturing technology is essential for commissioning and stimulation of these reservoir.However,there are some difficulties of separate layer fracturing about high-risk,hardship,indistinct stimulation effect etc.In combination with the geologic situations in gas reservoir of Sumatou Formation in the ... |
