摘要: 实时确定地层岩性是水平井地质导向钻井中的一个重要问题.介绍了一种基于随钻测井(LWD)和录井资料实时识别钻井近钻头处的地层岩性的实用方法.该方法从测井相分析的角度出发,充分利用随钻资料,并从中提取反映岩性的一些特征参数,建立随钻岩性统计模式,采用灰色关联分析法实时处理随钻资料,进而识别近钻头处的地层岩性.将其应用于新疆莫北油田3口水平井的地质导向钻井中,及时地提供了较为准确的岩性剖面,提高了水平井钻井中的随钻跟踪地质目标层的能力.

Abstract: A recognizing method based on logging while drilling and logging information for determine the formation lithology nearby bit in the drilling process of horizontal well was introduced.This method,in terms of logging facies analysis,makes full use of the information while drilling to extract some specific parameters for identifying formation lithology.The collection patterns of formation lithology were established.The data for recognizing rock-lithology nearby the bit were processed by means of gray conjunction analysis.This method has been applied to the practical drilling in three horizontal wells of Mobei Oilfield in Xinjiang area.The more accurate lithology profile could be provided in time.As a result,the geo-steering drilling ability was obviously improved.

Key words: logging while drilling, horizontal well drilling, formation lithology real-time recognition, grey conjunction analysis, geo-steering
