页岩气开发关键新型技术应用现状及挑战

Application Status of Key New Technologies for Shale Gas Development and Challenges

主要阐述了页岩气开发的关键性新型技术—"井工厂"技术的应用现状,对比分析了各压裂技术的优缺点及适用性。其中高速通道压裂以及纤维压裂两项新型技术能够避免常规清水压裂技术的缺点,有利于环保、低成本的页岩气开发。目前面临的许多问题和挑战,有必要对"井工厂"技术进行试验和推广;建立与规模开发配套的制度是现阶段开发的关键,而新型压裂技术的引进已成为战略需要。

With a specific illustration in the key new technology of ＂well factory＂, the paper compares and analyzes the pros and cons and applicability of the various fracturing technologies. The high-speed channel fracturing and Fiber FRAC fracturing avoid the disadvantage of the conventional hydraulic fracturing, being beneficial to environmental and low-cost shale gas development. For many of the issues and challenges currently facing us, ＂well factory＂ technology is necessary to be tested and promoted, the establishment of the system suitable for large-scale development is the key to supporting the current development, and the introduction of new fracturing technology has become a strategic need.
