Abstract: Wide differences of the physical properties of crude oiI in Daqing have necessitated the oil field to work out five types of oil gathering and delivery systems to cope with the severely cold climate of the region.These systems include,the gathering and delivery systems in Sartu with long operating radii and closely spaced pumping stations,suitable for well-pattern arranged in rows; the dual-pipe gathering systems operating on hot medium mixtures,with both heating and metering devices installed in the metering and pumping stations,simple and easy of operation; dual oil string systems heated at the well head,with simple single-well metering device,insignificant error and heat lasso the triple pipe systems run on hot water,suitable for pools with complicated geological conditions and law output,with higher heat loss and steel consumption,dual-pipe systems operating on activated water mixtore,a novel flow diagram,easy of operation and low in heat consumption,but with high cost of chemicals.Technical problems regarding viscosity reduction,wax cleaning and prevention,metering and closed delivery systems are reviewed in the pacer.

摘要： 大庆油田由十一个大小油田组成,不仅地处高寒地区,而且原油物性差异较大,这给原油的收集和输送带来了很多技术上的困难.二十年来,结合大庆地区的气候特点、原油物性和不同的注水方式,研究和选用了五种油气集输流程,较好地解决了原油集输贮运及初步加工问题.
