摘要
如何解决PDC钻头钻进的细碎岩屑录井问题,已成为地质录井界有关人士关注的焦点。该文基于自然伽马测井技术的原理和方法,简介了利用细碎岩屑进行自然伽马录井的方法,对实现井口连续自然伽马录井技术的可行性进行了探讨;提出了进行岩屑自然伽马录井的影响因素及解决这些因素的方法。相信对从事岩屑自然伽马录井技术研制与攻关人员具有一定的借鉴作用。
How to solve the logging problem of the fine cuttings drilled by PDC bits has become the focus that has been paid close attention to by the geological logging persons. On the basis of the principle and method of natural gamma well logging technology, the paper briefly introduced the method of how to use fine cuttings to conduct natural gamma logging, discussed the feasibility of realizing well-site continuous natural gamma logging technology, provided the influence factors of conducting cutting natural gamma logging and the methods of solving these factors. It is believed that the description in the paper is a certain reference for the persons who are engaged in studying and tackling the key problems of cutting natural gamma logging technology.
