摘要
以胜和1井为例介绍了现场随钻快速岩性鉴定技术的应用情况,该技术以其简便易行、快速准确的特点,对各种录井岩屑岩性进行鉴定和分析,并依据区域地质构造特征和岩性标志,为钻井取心、卡界面和目的层、判断井漏位置、选择钻头类型、地层分层等提供指导和参考意见,可有效提高钻井工程和地质录井质量及其经济效益。
Taking Shenghe 1 well as an example, this paper introduces the field application of rapid lithology identification while drilling technique It is characterized by simplicity, easiness, rapidness and high accuracy. It can be used to appraise and analyze lithology of drilling cuttings and provide guidance for coring, identification of interfaces and targets, determination of locations of lost circulation, selection of drilling bit and division of formations according to features of regional geologic structure and li-thologic markers. It can effectively improve the quality of drilling engineering and geologic logging and their economic benefits.
