摘　　要：大庆油田外围油田的集输系统绝大部分采用环状掺水流程,该集输系统受单井产量低,气油比低、井口出液温度低、集输半径大,原油凝固点高等因素的影响,集输系统生产能耗一直偏高。针对油田生产的这种现状,经过两年的现场试验及相关理论研究,给出了适合该类集输系统安全运行的技术界限,为外围油田环状集油工艺低温运行探索了新的途径,也为实现油田不加热集输提供技术支撑。Daqing Oilfield external field the vast majority of the gathering and transportation system using annular Water flow, the gathering and transportation system by a low single well production, gas-oil ratio low, low well- head fluid temperature, the radius of gathering and transportation, and higher freezing point of crude oil factors , gathering and transportation system has been the production of high energy consumption. Oil production for the sta- tus quo , after two years of field trials and related theoretical study, given the kind of gathering and transportation system for the safe operation of the technical boundaries for the outer ring oil field low-temperature process to run a new avenue to explore, also for the realization of heating oil gathering and transportation do not provide technical support.
