钻井模拟技术可为降低钻井成本和施工风险、提高钻井速度提供有力的辅助决策支持,目前仍然是国外的研究热点。掌握国内外技术现状和发展趋势是开展钻井模拟技术研究的重要基础。从钻井工艺流程操作训练培训模拟、钻井过程模拟、钻井技术经济评价模拟等3个方向,阐述了钻井模拟技术研究现状,分析了国内外有代表性的钻井模拟系统的功能和特点;从钻井模拟模型研究、钻井培训模拟器研制、钻井模拟系统研发等3个方面,分析了我国与国外先进水平的主要差距。在此基础上,提出基于虚拟现实技术的钻井模拟系统将是下一步钻井模拟技术研究与应用的主导方向;认为目前国内钻井模拟技术的研究重点将集中在地质模拟模型的研究与验证、钻前工程设计模拟优化技术、钻井过程的实时模拟与预测技术、基于实钻井的培训模拟器研制等方面。

Providing strong decision support in terms of reducing drilling cost,mitigating operation risk and improving drilling speed,drilling simulation technique is still the focus for overseas researches.Mastering the status and development trend of the technique at home and abroad is the important basis for carrying out studies on drilling simulation technique.From the perspectives of drilling engineering training simulation,drilling process simulation and drilling technical economic evaluation simulation,this paper described the status of domestic and overseas researches on the technique,and analyzed the functions and characteristics of the representative domestic and overseas drilling simulation systems.It also analyzed the main gaps between domostic and overseas advanced technologies from the three aspects of researches on drilling simulation model,drilling training simulator development and drilling simulation system RD.in addition,the paper proposed the drilling simulation system based on virtual reality technology would be the leading direction for further research and application of drilling simulation technology.Finally,the paper specified that domestic researches on the technique would focus on such aspects as the researches and verification of engineering geological simulation model,pre-drilling simulation optimization,real-time simulation and predication during the drilling as well as training simulator development based on drilling wells.
