Research on Parameters Correction Method for the Simulation Model of Oilfield Water Injection System
After years of operation of the oilfield water injection pipeline network,the friction coefficient of pipeline inner wall becomes greatly different from the original data due to the corrosion,scaling and other reasons,and it makes the calculation result of pipeline network adjustment exceed the allowable range of the project.Due to economic reasons and difficulties in the construction,it's impossible to conduct both pressure and flow tests on the whole pipeline network nodes to invert and solve the true friction coefficients of each pipe section.In this paper,through taking the friction coefficient of each pipe section of the pipe network as the research object,the finite pressure test points of the pipe network were taken as the known parameters to establish the inversion model of pipe network friction coefficient and the distribution model of pressure measurement points and having the improved artificial bee colony algorithm adopted to optimize the inversion model.The results show that,the calculation results stay within the allowable range of engi-neering errors.
