油气田井场工艺管线模块化施工工法
Modularize Well Process Piping Technology

近年来随着我国油气田发展速度加快、建设规模扩大，油气田采气单井井场地面建设工程在实际运行过程中，往往因为井下地质含沙、含水量超标，导致单井往往达不到设计使用年限，多数运行在10年以内，甚至有的单井使用年限只有2~5年，由此导致已投产完成的工艺管线和设备严重浪费，按照目前的工艺安装技术无法重复使用，只能重建新的单井工艺。传统施工方法多采用单井井场现场顺序组对安装，受单井采气树安装工期、工艺管线及设备土建基础成型制约，造成施工周期长、占用成本高等问题。
As the development of oil and gas fields in our country, the construction scale and wells of oil & gas has expanded dramatically. In actual operation, due to the underground geological tainted with sand, water, the well often cannot meet the design life; most of the wells’ running life is less than 10 years; some wells even only run 2 to 5 years. According to current specification requirements, well process piping facilities cannot be reused. This results in significant waste of well process piping facilities already in production. Traditional construction methods mostly adopt well site sequential installation, which is restricted by well gas tree installation period, process pipeline and equipment civil foundation, leading to long construction cycle and high occupancy cost. Modularizing well process piping technology can greatly shorten the construction period, reuse some well-functioning modules, and reduce the construction cost.
