Abstract：
Shale gas development mainly depends on long horizontal well drilling technology and large-scale fracturing technology. With the shale gas revolution, the development of fracturing technology is particularly important. Patents are the comprehensive carriers of technological and commercial value of technology or products. With the advent of the era of big data, the application of big data analysis technology to the field of patent analysis can extract and mine high-value information from massive data sets more efficiently, thus analyzing the latest technological trends and related industry dynamics more quickly and efficiently. This paper uses patent data analysis tools to collect, collate, quantify, and conduct expert research on global shale fracturing patents. It reveals global shale fracturing from various perspectives such as development trends, geographical distribution of technology, technology categories, and patent holders. The technical patent situation in the field of fracturing provides reference for the development of domestic shale fracturing technology.
