摘要
针对当前世界范围内研究热点之一的页岩气资源,对钻井过程中的页岩气快速评价方法进行了初步探讨。首先对页岩气录井评价要素进行了分析;然后论述了页岩气录井评价手段。通过常规及特殊录井技术的应用实例,说明了录井技术在获得页岩储层的有机质含量、成熟度、矿物组成、脆度、含气量等评价要素方面的重要作用。建议尽快形成页岩气录井技术系列,以便对页岩气藏做出快速准确评价,加快勘探开发节奏。
Aiming at current research of shale gas resources which was the focus of its research worldwide,the methods of rapid evaluation of shale gas during well drilling were preliminarily discussed.By using practical cases of conventional and special mud logging techniques,the important role of mud logging is elaborated including such elements as TOC,maturity,mineral composition,brittleness,gas content of shale.It is proposed that mud logging technological series of shale gas should be formed as soon as possible,then a rapid,accurate evaluation on shale gas can be made to accelerate the pace of exploration and development of shale gas.
