把钻井工程相关专家的经验和知识以及从大量数据中提取的信息有机地汇集起来，通过建立一个基于油气田内部互联网上的石油钻井知识共享体系,使现场作业人员能及时获取和共享，对提高钻井决策水平起着重要作用。文章介绍了知识共享体系的概念，提出建立钻井知识共享体系的关键环节是联系钻井各部门网络环境的建立、知识管理和知识共享标准和协议的制定以及有资质的专家群体对该体系的管理和维护。特别强调要改变现行的工作方式，致力于营造知识共享的应用环境，使钻井工程技术人员无论何时、何地,做任何决策时都能想到、都能获得、都能充分应用所需要的决策支持。该体系将改变传统的石油钻井决策模式，使多方专家不受时空限制，通过知识共享，充分利用现有的知识和经验，及时作出最优钻井决策。

ESTABLISHMENT OF SHARING SYSTEM AND ENVIRONMENT OF DRILLING KNOWLEDGE 1)

Gathering the experience and knowledge of drilling experts and information taking from large data, a sharing system of drilling knowledge will be established on the internal internet of oil/gas fields for the field operating persons to obtain and share the knowledge, which will play important role to improve the drilling decision-making level. The article introduces the concept of knowledge sharing system and indicates the key link to establish the knowledge sharing system is to build the network circumstance connecting every drilling unit, make the standards and protocols of knowledge managing and sharing, handle and maintain the system by a qualified expert team. Special stress is made to change the current working mode, and create the application environment of knowledge sharing for drilling technicians to obtain the required decision making supports to their decision at anytime and anywhere. The system will change the traditional drilling decision-making mode. So, the drilling technicians may not be limited by time or space. With knowledge sharing, the existing knowledge and experience will be used fully to make the optical drilling decision in time.
