摘要
随着世界浅层石油资源不断减少,石油开采不断向地球深处延伸,最深的油井已经超过一万米,假如油套管的米重每增加0.1kg,整个重量就会增加1000kg,会大大增加油管连接螺纹受力,极有可能出现油管螺纹失效,继而油管掉井的风险。因此每支钢管的几何尺寸及长度、米重必须满足API(美国石油协会)标准要求。为满足用户要求,设计开发了钢管在线测长称重系统,该系统包括钢管测长、称重、喷标及数据管理四个模块,文中重点叙述系统在线测长、称重的构成、原理与实现过程。通过在线测长称重系统应用,成功实现油套管生产过程中单支测长、称重和特殊标志喷标技术,以及根据米重与长度自动判别油套管好坏,达到了API标准。
With the shallow world oil resources decrease,oil exploit will extend to the depths of the earth.Therefore,pipe＇s size and length,meters per branch pipe weight must meet the API standards.This paper analyzes emphatically the work principle of the online length measuring,weighing and spraying,focusing on introducing the parameter design,information and data man- agement applications during the producing process.Through system applied not only successfully implement the oil casing production process of single length measuring,weighing and special signs spraying technology,and can automatically deter- mine the quality up to the API oil pipe standards.
