摘要:
磁測應力方法是一種可以直接測得鋼套管內壁應力分布的新技術。磁測應力信息能夠解釋套損危險程度和水驅力的方向;套損危險程度與應力檢測儀器的信號幅度和發生信號異常的極板數量成正比;應力信號的極性代表套管被擠壓或拉伸方向,應力值與信號幅度成正比;由6個極板測量的數據信息構成的平面矢量圖對解釋分析套管受力方向及其相對大小具有實際意義。根據工程需要提出了視應力值的概念,應當從理論和實驗2個方面探索磁測應力儀器的刻度方法,這對該項技術發展完善很重要。
Abstract:
Magnetismstress logging is a new technology which can directly measure stressdistribution of steel casing. The log data can be used to estimate degree of casing damages and direction of waterflood pressure. The degree of casing damage is in direct proportion to the signal amplitude of the MSTⅡcasing stress detector and numbers of polar plates with abnormal signals. The polarity of the stress signal indicates the extruded or stretched direction of the casings. The stress value is directy proportional to the signal amplitude. The plane vector chart with 6 polar plate measuring data may be used to interprete the degree of the casing damages. Imaging processing of the magnetismstress logs is a new trend. Calibration methods will be studied in theories and with experiments. A new concept of apparent stress is suggested here.
