摘要
美国页岩油气革命成功的秘诀是技术创新,关键是技术组合.北美页岩油气开发应用的技术组合主要包括:1)"甜点区"预测技术组合精准快速定位油气"甜点";2)"一趟钻"技术组合提高水平井作业效率;3)"长水平井+超级压裂"技术组合提高单井产能.中国在找甜点、一趟钻、体积压裂等方面均与美国存在一定差距.为此建议:一是充分发挥技术组合在油气上游业务中的作用;二是以核心技术为中心形成技术系统;三是研究制定与技术组合配套的发展策略.这些技术发展措施对中国石油企业实现上游增产降本提效具有重要意义.
The secret to the success of the US shale revolution is technological innovation,and the key is technology combination.The technology combination in the shale oil and gas development in the North America includes such three aspects as 1)predictable technology combination in the"sweet point”area accurately and quickly positions the oil and gas“sweet point";2)"one-run drilling,^technology combination improves horizontal well operating efficiency;3)the combination of"long horizontal well+super fracturing"technology improves the productivity of a single well.The comparative analysis shows that there is a gap between China and the US in these three aspects.The paper suggests giving full play to the role of"technology combination"in upstream,forming technical system with core technology,and formulating development strategies corresponding to"technology combination";which are of great significance for Chinese petroleum enterprises to achieve their upstream production increase,cost reduction and efficiency improvement.
