随着国内外油气田规模的不断扩大和产量的不断增加,部分炼油厂无论是在功能还是在规模上都已经不能满足石油炼制的需要,因此需要拆除、更换、新增大量的设备和工艺管线等。然而,由于炼油厂几经改造,现有的炼油厂图纸资料并不完整,不能满足炼油厂改造扩建的需要,给设计工作带来了很大困难。为了给设计工作提供基础输入资料并且为后续的运行维护和管理提供很好的基础数据平台,需要对炼油厂进行现状测量以获取现场设备和管道的位
With the continuous expansion of oil and gas fields at home and abroad and the continuous increase of output, some refineries can no longer meet the needs of oil refining both in function and in scale, and therefore require the dismantling, replacement and addition of large quantities of equipment and process lines Wait. However, due to the refinery reform, the existing refinery drawings are not complete, and can not meet the needs of refinery reconstruction and expansion, which brings great difficulties to the design work. In order to provide basic input data for design work and provide a good basic data platform for subsequent operation, maintenance and management, the status quo of the refinery needs to be measured to obtain the location of the field devices and pipelines
