新形势下的录井技术需求与应对策略

The Demand and Response Strategy for Mud Logging in the New Situation

摘要: 现场及时准确的岩性剖面建立、地层可钻性评价、取心层位卡准、油气水层判别、钻井风险监测、数据信息发布等是录井技术在随钻过程中最重要的优势，也是区别于其他专业的显著特点。录井所采集的现场第一手资料，经过正确的分析处理后获得的数据和成果，能为油气田勘探开发提供重要的参考依据。在分析了油气勘探开发在现场录井中遇到的如岩性识别、物性判断和油气水层评价方面的困难，结合录井数据采集、资料处理、解释评价和信息技术的发展现状，提出了录井行业在资料采集智能化、数据处理模型化、解释评价随钻化和信息发布多样化等方面的发展前景。

Abstract: Some advantages of mud logging while drilling included accurate determination of lithologic profile timely on site, evaluation of formation drillability, locating the coring horizon, the identification of oil, gas and water layers, monitoring of drilling risks and data release, which were also the evident characteristics for distinguishing the mud logging from other disciplines. The data and results obtained from proper processing of first-hand data from mud logging can provide crucial basis for oil and gas exploration and development. After reviewing the difficulties such as lithologic identification, physical property judgment, and oil, gas and water layer evaluation encountered in mud logging, some development directions for mud logging, including smart data collection, modelized data processing, interpretation and evaluation while drilling, and diversified information release forms etc are proposed according to the status quo of data collection, data processing, interpretation and evaluation of mud logging technology and information technology.
