大庆外围油田普遍采用的集输流程是单管环状掺水集油流程 ,每个集油环串联井数的多少没有严格的界限。对于不同的区块 ,集油环串联井数的多少应根据具体条件而定。对于大庆外围油田来说 ,一般单井产量为 4t/d左右 ,井距为2 5 0～ 5 0 0m ,集油环串联井数通常为 4～ 7口 ,集油环管道的长度在 4km以下较为合理
The common collection and transportation process in the peripheral oilfields in Daqing is the single-pipe annular water-mixing and oil-gathering process. There is no strict limit on the number of wells in each oil gathering ring in series. For different blocks, the number of oil wells connected in series should be based on the specific conditions. For the peripheral oilfield in Daqing, the general single-well output is about 4t / d and the well spacing is 250 ~ 500m. The number of wells in series with the oil gathering ring is usually 4 ~ 7, and the length of the oil gathering pipe is below 4km More reasonable
