四十臂井径仪测量臂机构的改进与应用

摘要

The 40 arm caliper is a casing monitoring instrument.It can describe the maximum and minimum inner diameter of the casing and the damage,shrinkage,diameter expansion and fault of the casing.Departments to develop measures to provide a reliable basis.Main introduction In order to solve the design arm of the existence of the design flaws caused by the field test when some of the measuring arm can not normally open,after the test can not be fully recovered and measuring arm excessive replacement due to excessive wear and tear on the arm of the arm to improve and Field application effect.This paper analyzes the status quo and puts forward solutions to improve the accuracy of test data and reduce the cost of testing and labor intensity of the purpose of operating staff.%四十臂井径仪是一种油层套管监测仪器,它能够描绘出套管的最大、最小内径以及套管的扭曲、缩径、扩径、错断等损坏情况,为地质、工程部门制定措施提供可靠的依据.主要介绍为了解决因测量臂机构存在设计缺陷导致在现场测试时一些测量臂无法正常撑开、测试完毕后不能完全收回和测量臂因磨损过度大量更换的实际问题,对测量臂机构进行的改进和现场应用效果.针对这种现状进行了分析,并提出解决方案,以达到提高测试资料的精确性、降低测试成本和操作员工劳动强度的目的.
