用弹塑性断裂力学的观点解释冶勒水电站第三岩组水泥帷幕灌浆取得成功的机理，正确描述了在强团结、弱胶结的地层劈裂灌浆的三个力学效应──劈裂的浆刃效应、充填的扩张效应、挤密的回弹效应。基于地层厚度、裂纹长度与裂纹张开宽度之... 详细信息

用弹塑性断裂力学的观点解释冶勒水电站第三岩组水泥帷幕灌浆取得成功的机理，正确描述了在强团结、弱胶结的地层劈裂灌浆的三个力学效应──劈裂的浆刃效应、充填的扩张效应、挤密的回弹效应。基于地层厚度、裂纹长度与裂纹张开宽度之比甚大，提出了采用无限板宽的半无限裂纹的合理近似假定，从而为求解灌浆中的相关参量确定了较为合适的效学模型。对G·隆巴迪有关浆液的最大扩散放半径、最大灌入量和最大总的上抬力的理论计算公式提出了修正意见。

提高对套铣的认识,确保套铣和大修成功

科技传播 2010年第20期2卷 42-42页

作者：范天龙玉门油田作业公司塔里木分公司甘肃酒泉735000

塔里木油田多为疏松砂岩油藏,完井作业时要求进行防砂。在油井的生产过程中,随着生产时间的增长,有许多油井已经开始出砂,造成停产,损失巨大。只有进行大修作业,将原井内防砂管柱打捞出来,重新进行防砂。在大修过程中,套铣作业是一项必... 详细信息

塔里木油田多为疏松砂岩油藏,完井作业时要求进行防砂。在油井的生产过程中,随着生产时间的增长,有许多油井已经开始出砂,造成停产,损失巨大。只有进行大修作业,将原井内防砂管柱打捞出来,重新进行防砂。在大修过程中,套铣作业是一项必不可少的工序,该作业相对比较复杂,且风险很大,操作不甚甚至会出现卡钻的恶性事故。本文在对套铣进行理论分析和实践操作的基础上,总结出了许多经验,对套铣有了深刻的认识,有利于提高套铣质量,减少风险,确保大修的成功。
