To ensure that the J-S oil pipeline in a certain block of the North China Oilfield can operate safely under low throughput,this paper applies two technical schemes of oil-gas mixed transportation and low water content oil transmission for comparative analysis.It is preferable to reduce the J-S pipeline lowest starting capacity and starting temperature by the operation mode of oil-gas mixed transportation.A new associated gas compression,injection,and venting system is built at station J and a new separation,and a filtration and venting system is built at station S.The flow rate of the medium in the pipeline is improved by using the flow characteristics of the two-phase flow in the pipeline,and the rich associated gas resources of station J are transported to station S through pipeline transportation.The design is simulated by PIPESIM software and HYSYS software,and the calculation results aremutually verified.This scheme not only solves the problem of safe operation of J-S pipelines with low throughput but also alleviates the contradiction between the uneven distribution of resources associated with J Oilfield and S oilfield,reducing the crude oil production cost of oilfields.
