摘要
混油钻井液增加了地质录井岩屑描述的难度,使原有的荧光、气测录井不能准确反映地层真实油气信息。为了消除混油钻井液体系对现场地质录井的影响和干扰,准确落实岩性剖面和油气层,经过多口井的现场实践,并结合新疆探区油气地质录井规范,对不同的录井手段进行了有针对性的改进,提出了在相应的混油钻井液井段真假油气显示层的识别方法。通过测井、完井测试,验证了改进后录井方法的有效性和可靠性。
Oil emulsion drilling fluid increased the difficulties of geologging cutting description, it made the original fluorescence logging and gas logging reflect the real formation oil and gas information uncorrectly. In order to eliminate the effect and disturbance of oil emulsion drilling fluid on on-site geologging, correctly judge lithological profiles and pay zones, through practice on many wells, combining with oil-gas geologging specifications of Xinjiang exploration region, the improvement was made corresponding to the different mud logging means, the paper put forward the identifying methods for true and false oil-gas showing layers at the corresponding oil emulsion intervals. The wireline logging and well completing test verified that the above improved methods were effective and reliable during mud logging.
