摘要/Abstract

摘要： 针对深井、水平井广泛使用的盐水钻井液,分析了盐水钻井液侵入对电性特征的影响,并通过盐水钻井液侵入前后实验对比研究了盐水钻井液对录井分析结果的影响。实验发现:由于岩屑(心)在井筒内浸泡时间短,受盐水钻井液影响小,录井数据能准确地还原地层岩性、含油气性的真实特征。实践证明,在采用盐水钻井液钻探时,可充分利用录井技术的优势,在岩性识别、储集层解释评价以及随钻地质导向等方面发挥显著作用,更好地服务于油气田勘探开发。

关键词: 录井技术, 盐水钻井液, 岩性识别, 解释评价, 地质导向

Abstract: Aiming at the brine drilling fluid widely used in deep and horizontal wells,the influence of brine drilling fluid invasion on electrical characteristics was analyzed,and the influence of brine drilling fluid on logging analysis results was studied through experiments before and after brine drilling fluid invasion. Experiments showed that due to the short immersion time of cutting(cores)in the wellbore and little influence from brine drilling fluid,logging data can accurately restore the true characteristics of formation lithology and hydrocarbon bearing. It was proved that the advantages of logging technology can be fully utilized when using brine drilling fluid for drilling,which played a significant role in lithology identification,reservoir interpretation and evaluation,and geosteering while drilling,and was conductive to the exploration and development of oil and gas field.

Key words: mud logging technology, brine drilling fluid, lithology identification, interpretation and evaluation, geosteering
