摘要

摘要: 美国俄克拉荷马州伍德福德(Woodford)页岩区带是美国近年来新兴起的重要的非常规页岩油气生产区之一,其覆盖区域包括阿纳达科(Anadarko)盆地、阿德莫(Ardmore)盆地、阿卡马(Arkoma)盆地和切罗基(Cherokee)台地。伍德福德页岩是北美重要的泥盆系富含有机质页岩,有机质含量最高可达14%。伍德福德页岩甜点区域位于凝析气或成熟油窗,页岩的镜质组反射率(R_o)为0.6%~1.4%,岩层厚度超过20 m;底部必须具有厚度至少15 m以上的隔层,以防止压裂串通上下含水层;具有有机质含量高达7%的岩层和燧石层等脆性夹层,裂缝发育程度高,钻井位置必须避开大型断裂。根据甜点控制因素,设计具有针对性的钻完井方案,降低钻探风险和成本,可以获取较高的开发效益。

Abstract: The Devonian Woodford shale play in Oklahoma is one of the big unconventional shale oil and gas production fields in USA, which covers the Anadarko, Ardmore and Arkoma basins and Cherokee Platform. The shales are rich in organic matter, with the maximum content of 14%. They have entered condensate gas or mature oil windows. The vitrinite reflectance (R_o) values range from 0.6% to 1.4%. Shale thickness exceeds 20 m. The water isolating layer beneath the shale formation should be at least 15 meters thick to avoid fractures made by hydraulic fracturing reaching the water bearing layer. Shale formations with a TOC content of 7% with chert layers with well developed fractures are the most promising. Well locations should be far away from major faults. Based on the attributes of sweet spots, we should design a specific drilling program to reduce drilling risk and cost and achieve high profit.
