摘要/Abstract

摘要： 页岩油气井的重复压裂是近年美国页岩油气行业重点关注的技术之一，其在改善页岩油气井生产特征和增加单井EUR 方面取得了不错的效果，但同时也面临技术适应性、经济性、不确定性等方面的挑战，目前研究热点及发展趋势是建立适合作业区的选井标准、可膨胀衬管技术、精确的产量预测模型、新型材料的压裂液和支撑剂，指出页岩油气开发需要持续技术创新，重复压裂作为重要的创新方向，虽尚不成熟，但发展前景良好，随时关注并适时开展相关研究，将会助力我国页岩油气开发。

Abstract: Re-fracturing of shale oil and gas wells has been one of the technologies highlighted in the United States in recent years. This technology has made good performance in improving production characteristics of shale oil and gas wells and increasing the single-well EUR. However, it also faces some challenges, such as technological adaptability, economic feasibility and uncertainty. Currently, this study and its development trend are focused on establishment of the standards for selection of wells suitable for service zones, expandable liner technology, accurate production-predicting model, and fracturing liquid and proppant of new materials. Shale oil and gas development calls for continual technological innovation. As an important innovative direction, re-fracturing has a bright prospect for development though it is still under immaturity. The study made in this area will help China with its shale oil and gas development.
