With the development of the three oil extraction technology,the traditional water flooding technology has been replaced by polymer flooding technology in the exploitation of remaining oil and the collection of high permeability layer.Because of the contradiction between layers,a stratified polymer injection process was developed to further improve polymer flooding recovery.Stratified polymer injection technology can effectively solve the problem of uneven collection between different layers.The polymer solution is a non Newtonian pseudo plastic fluid,which is subjected to mechanical shearing through the injector.Therefore the spool structure design,need to maintain the viscosity of polymer solution.The number of injection wells and the number of layers increases continuously,and the workload increases year by year.In order to improve the extraction rate of polymer flooding,solve some disadvantages now layered polymer injection,developed a set of effective injection technology of poly for the remaining oil.This paper is to carry out research work to solve the facing problems in the extraction of 13 times on the development of intelligent cable,pre injection into testing process,solve the injection production,due to mechanical shearing,the viscosity loss of polymer,is not able to continuously adjust the opening degree of the nozzle,the process of implementation.Multi period synchronous measurement,real-time monitoring,real-time control of polymer flow,the continuous adjustment of the objective.It not only meets the requirements of polymer production machinery,but also applies electronic controlled oil production to polymer flooding oil recovery.Improve the monitoring accuracy and efficiency,provide technical support for the three oil recovery automation mining.According to the requirements of the technology of polymer flooding,polymer flooding control design of intelligent distribution system of poly injector layered injection pipe column,control the CPU STM32 as the core controller,including: underground continuous adjustable linear motor,and pressure acquisition module,adjusting applied to oil,PC using VS2008 development environment,the oil workers in measuring and adjusting studio to complete the data exchange,timing acquisition,real-time monitoring,and provides the starting conditions for the subsequent development of oil flooding block.
