1、11级钻井技术（修井专门化）专业毕业设计（论文）题目：学号：姓名：专业：班级：指导教师：完成时间：年月日硅酸盐钻井液体系研究摘要硅酸盐钻井液被普遍认为是最具发展前景的水基钻井液体系Z-O辽河油田所处地质情况复杂，井壁不稳定问题一直存在，但硅酸盐钻井液体系口前对于辽河油田来说还是空白，因此结合辽河油田的实际情况研究硅酸盐钻井液体系，对避免或减少辽河油田深井复杂情况的发生、提高钻井速度和质量有着十分重要的意义。木课题是辽河油田工程技术研究攻关课题，木文结合辽河油田深井井壁稳定问题开展了硅酸盐钻井液研究。分析了硅酸盐模数、加量、pH值、处理剂类型、温度等因素对硅酸盐钻井液体系性能的影响，在此

2、基础上研究硅酸盐钻井液的配方，并讨论硅酸盐钻井液的作用机理。研究结杲表明，硅酸盐模数以2.8-3.0为好，加量在5%左右较好。硅酸盐钻井液具有多种机理并行的抑制功能，是一•种具有强抑制性能的钻井液，硅酸盐钻井液的流变性、滤失性都可以满足钻井需要，具有广阔的应用前景。关键词：硅酸盐钻井液；模数；机理；井壁稳定DrillingfluidsystemofsilicateAbstractSilicatc-baseddrillingfluidsisakindofwater-basedsystemdrillingfluidswhichiswidelyregardasthemostprospccti
