页岩气录井技术要点及对外合作启示

页岩气的开发最早始于美国,是目前国内非常规气藏的勘探重点和热点。简介了国内外页岩气勘探开发现状,页岩气工业化开采因具有产量低的特点,需要采用相应的钻井新技术,以便缩短钻井周期,降低成本。为了卡准层位、发现储集层、准确预报工程异常和油气显示,录井主要应用了微钻时、岩石可钻性、气测、岩石热解、岩屑显微图像、随钻伽马等技术对页岩气储集层进行评价,取得了较好的效果。川庆录井在和壳牌合作过程中,发现壳牌公司录井在资料采集、数据准确、井控异常、录井报告、安全管理和人员能力等方面的相关要求和做法,有许多值得国内录井学习和借鉴的经验。

The technical points and foreign cooperation revelation from shale gas mud logging

The development of shale gas initiates in the U.S..The shale gas is the exploration key and hot spot for the current domestic unconventional gas reservoir.The paper gave a brief introduction to the state of domestic and foreign exploration and development to the shale gas.Because the industrialized exploitation of shale gas has the feature of low output,which needs to adopt the new corresponding drilling techniques to shorten drilling period and reduce the cost.In order to correctly stick horizons,find rese...
