摘要
鄂尔多斯盆地是我国重要的致密油生产基地,也是我国未来主要的油气接替区之一。鄂尔多斯致密油某区块具有鄂尔多斯致密油藏的典型特点,天然裂缝发育程度和区块构造对致密油产能具有重要影响。为提高致密油藏的开发效果,建议生产井水平段长度设计为400~450 m之间,采取5段非等间距的压裂改造方案,并在泥岩层下增设水平井段。鄂尔多斯致密油某区块的产能优化方案研究,对开发其他同类型的油藏具有一定的指导意义。
The Ordos Basin is an important tight oil production base in China,and it is also a main oil and gas replacement area in the future.A certain block of Ordos tight oil has the typical characteristics of Ordos tight oil reservoir.The developing degree of natural fractures and structure have an important influence on tight oil production.In order to improve the development effect of tight oil reservoirs,it is recommended that the length of the horizontal section of the production well is designed between 400 and 450m,and f ive non-equal interval fracturing plan is adopted,and horizontal well sections are added under the mudstone layer.The research on the productivity optimization plan has certain guiding signif icance for the development of other oil reservoirs of the same type.
