Abstract

本实用新型轻型抗震测斜仪为一种石油地质钻井测斜仪器。主要由电源、控制器、照相机、测量筒总成构成,采用阻尼机构和一体化结构,使之能在震动环境下精确测量井斜、方位、工具面角。

Description

轻型抗震测斜仪
本实用新型涉及一种石油地质钻井工程中测量井的斜度和方向及工具面角的测量仪器,特别适合自浮式测斜中要求的仪器质量小和在震动环境中完成精确测量的要求。
自浮式测井是利用钻井工程的泥浆冲力将仪器及其载体送到井底,停泵以后依靠载体的浮力上浮到井口,获得测量数据。由于仪器测量工作时得开泵使仪器停留在钻头处,在液体冲击力作用下仪器震动很大,现有仪器均不能测出准确数据。
本发实用新型的目的在于提供一种轻型抗震测斜仪能。使其在上述条件下稳定工作,并准确测量记录数据。
附图:轻型抗震测斜仪结构示意图
以下结合附图详细说明本实用新型。本装置主要由充电式电源3、控制器4、照相机5、测量筒总成9构成。充电式电源3和控制器4、照相机5为封闭在壳体11内的一体化结构。照相机5下部螺纹连接测量筒总成9。测量筒总成9为一密闭结构,其内腔中充满阻尼液7,并浸没安装有测角机构6和罗盘8构成。测量筒总成9下设有定向测斜用卡口10。阻尼液为阻尼系数1-20厘沲(25°)的透明液体。
实施例:当仪器随测井仪器运载装置下到井底时,由于井底的实际井斜的作用使得测角机构6偏离仪器轴线,在罗盘8上的投影可反映倾角的大小和方向。充电式电源3始终向控制器4供电,控制器4控制照相机5的拍照时间。由于测角机构6和罗盘8浸没在阻系数较大的阻尼液7中,不易产生受震动引起的不稳定抖动,所以在震动环境中仍能清楚地拍出反映井斜参数的图形。
本实用新型将充电式电源3和控制器4及照相机5制成一体结构,减小了其体积和重量。采用适当阻尼系数的阻尼液7,解决了震动环境中测斜的问题。
