摘要:
石油钻井施工过程中产生大量的岩屑等废弃物,对这些废弃物的处理需要较高的成本。岩屑回注技术应用地下灌注方法处理钻井废弃物,是一种环保有效的处理方法。在厄瓜多尔ITT区块生产实际中,根据回注层位裂缝的延展性能,优选回注层位;分析了研磨对颗粒细度的影响,优化了岩屑浆料的各种参数;通过注入压力、排量等参数优化,酸化解堵效果评价等,制定了适用于目标区块的岩屑回注技术,并在TBTP-20井现场应用,共回注岩屑18.9×104 m3,有效保证了41口井正常生产。
Abstract:
During the construction of oil well drilling,a large amount of wastes such as cuttings are generated,and the treatment of these wastes requires higher costs. The cuttings reinjection technology applies underground injection method to treat drilling waste,which is an environment friendly and effective treatment method.In the actual production of the ITT Block in Ecuador,according to the ductility of the fractures in the reinjection layer,the reinjection layer was optimized; the influence of grinding on the particle fineness was analyzed,and various parameters of the cutting slurry were optimized.Through the optimization of injection pressure,displacement and other parameters,and the evaluation of the effect of acidification and plugging removal,etc.,a cuttings reinjection technology suitable for the target block was formulated and applied in the TBTP-20 well,with a total of 18.9×104 m3 of cuttings reinjected,effectively ensuring the normal production of 41 wells.
