| 摘 要： | 孤岛油藏馆陶组上段沉积韵律多变,每个地质层段,甚至同一层段的不同部位其岩性、物性、渗透性都不相同,采用普通射孔技术时原油采收率低.提出针对不同物性的地层,在其他射孔参数不变(最优的孔深、孔径、射孔方位等)的情况下,使用不同的孔密进行优化射孔.对应用变孔密射孔技术调整产液剖面、提高水驱、聚驱效果的可行性进行了分析,结合孤...

| Abstract: | The upper Guantao Formation of Gudao Oilfield features changeful sedimentary rhythmic,which is different in different geological formations.Even in the same formation,the lithology,physical property and permeability are diverse in different locations,which causes oil recovery factor low when perforating in ordinary way.Proposed is a variable density optimization perforating method for formation with different physical properties in condition that other perforating parameters(optimized perforation length,per... |
