| 摘 要： | 近年来大港油田低渗透油藏在未动用储量中的比例日益加大。针对低渗储层施工难度大、开发效果不理想等难点,进行了水平井裸眼分段压裂投产一次完井技术研究,并对完井管柱、分段数量及长度、压裂参数等进行了优化设计。现场实践证明,合理应用水平井技术开发低渗储层,能够缩短作业时间,提高储层动用程度,实现经济高效开发。

| Abstract: | The proportion of low permeability reservoirs is increasing among undeveloped reserves in the Dagang oilfield in recent years.These reservoirs are difficult to develop and hard to achieve ideal result.Therefore,the technology of multistage fracturing and producing from horizontal openhole through one trip completion has been researched through optimization of completion string,the number and length of fracturing sections,and fracturing parameters.Field practice has proved that proper application of horizont... |
