多底井、分支井工程设计原则及方法

Engineering Design Principles & Methods of Multi-bore and Lateral Wells

多底井、分支井能提高原油采收率、增加产能和节约成本 ,其钻井工程设计的合理性与完备性 ,是实施分支井钻探的关键和前提。介绍了多底井、分支井类型选择及井眼轨迹优化设计、侧钻方式选择、钻柱设计、钻井液设计和完井方式设计的原则和方法。

Multi-bore and lateral wells can improve the oil recovery efficiency, increase productivity and reduce cost. The reasonability and perfection of drilling engineering design are the key and precondition to drill lateral wells. The principles & methods of type selection, optimum design of well trajectory , selection of sidetrack ways, design of drill strings & drilling fluid and completion design are introduced in this paper.
