日光油田Cardium组致密油大位移水平井钻井实践

Shiyou jixie, 2014
针对日光油田Cardium组致密油开发需要大量高效低成本的水平井钻井和多段压裂等特点，研究并应用了致密油大位移水平井钻井技术。考虑大位移水平井复合钻井的特殊要求，建立了三段组合圆弧井眼轨道模型，深入研究了井身结构、油基钻井液、钻头优化和钻具组合等关键技术。对3口先导试验大位移水平井丛式井组和3口相邻水平井丛式井组的经济效益进行了评价，评价结果表明，其平均每米水平段长度的钻完井费用比相邻丛式井组节约22%、钻井周期比相邻丛式井组减少42%，其初始平均日产量和6个月总产量分别是相邻丛式井组的1.6倍和1 ...
