| 摘 要： | 以钻进趋势角作为评价指标,对使用随钻扩眼工具进行钻进时的钻进趋势进行了分析.结果表明:对于偏心扩眼钻头,钻压分配比在一定条件下能够改变钻具的钻进趋势,因此在钻具组合设计中不能按照常规钻头来对待;对于钻具组合设计,将扩眼体位于井眼高边时是否满足防斜要求作为设计依据;对于独立结构扩眼器,钻压分配比的变化通常对钻具钻进趋势的影响较小,独立结构扩眼器的防斜主要依赖于领眼钻头与扩眼器之间稳定器位置的调节.

| Abstract: | Taking drilling tendency angles as evaluation parameters,the drilling tendencies of reaming while drilling(RWD) tools were analyzed.The results show that for eccentric reaming bits,the ratio of weight on bit(WOB) may have a great effect on the drilling tendency in certain conditions,and RWD tools can not be treated as the normal bit in the process of bottom hole assembly(BHA) design.And it can be the design foundation that the design parameters of BHA can meet the demands of borehole inclination when the re... |
