Research Progress and Development Direction of Hydrofracturing Design Models

Abstract

Abstract: Hydrofracturing model is the basis of hydrofracturing design,and also the crux where current bottlenecking problems lie. In order to promote the development of fracturing design models and softwares in China,fracture propagation models,numerical methods and popular commercial softwares for hydrofracturing are systematically analyzed,and their future development orientations are predicted. Research findings show that (1) Planar and complex fracture models are different in application conditions and accuracy. Most commercial softwares are planar fracture models-based,and most complex fracture models are pseudo-three-dimensional ones. (2) It is the focus of fracturing design softwares to develop models with satisfactory accuracy and efficiency. (3) Artificial intelligence data-driven fracture analysis,and fracture parameter inversion based on micro-seismic and fiber optic logging are the development orientation of fracturing design models.

Key words: fracturing model, numerical method, fracture geometry, software development

摘要： 压裂设计模型是水力压裂设计的基础,也是当前“卡脖子”工程问题的症结。为推动国内压裂设计模型及软件研制,系统分析了水力压裂裂缝扩展模型、数值计算方法、主流商业软件,并分析了未来发展方向。研究认为：（1）平面模型、复杂裂缝模型适用条件、精确度有差异,大部分商业软件是平面裂缝模型,复杂裂缝模型目前以拟三维模型为主;（2）研制精度和效率兼顾的模型是压裂设计软件的重点;（3）人工智能数据驱动裂缝分析、基于微地震和光纤测井的裂缝参数反演是压裂设计模型的发展方向。
