Oil Gathering Technology Of Qing Xin Oilfield Oil Catch Ring In Low-temperature Process

Daqing oil field in the late oilfield produced fluid entering into high water cut exploitation stage, crude oil gathering and transferring energy consumption has risen sharply,take up little about engineering more than 70% of the energy consumption. The current total of oil production in daqing oil field fluid volume increased year by year, wellhead oil temperature was increased, with parts of oil Wells of implement annual or seasonal temperature gathering, even stop blending transportation condition.With the celebration of the new field produced liquid total liquid amount rise ceaselessly,pipeline volume increases continuously, pipeline energy consumption is growing fast. In order to reduce the energy consumption in the process of crude oil gathering and transferring, in view of the circular gathering and transferring process, on the analysis of crude oil wax characteristic parameters and low temperature rheological property were analyzed, indoor simulation experiment was carried out at the same time, determine the security under the condition of low temperature gathering and transferring the boundaries of different working conditions. And study the low temperature gathering and transferring pipeline wall deposition law of sediment, combined with field test to optimize operation parameters of the new oil low temperature gathering and transferring. Using the method of thermodynamic calculation and hydraulic calculation method for the pipe temperature drop model, reduce energy consumption of the ground and ensure safety of oilfield production, convenient for production management, improve the accuracy of the evaluation analysis provide important support. The implementation of low temperature gathering and transferring can control and reduce the heat loss of crude oil gathering and transferring system, save a lot of resources, is one of the main measures to reduce the energy consumption of oil and gas gathering and transferring.
