Abstract


Hydraulic pressurized single well the increasing injection system using water trunk water pressure as power source , the use of the differential piston area boosting water injection , stable and reliable , low cost , has a better economic and technical indicators . A structure composed of a the hydraulic pressurized single well increasing injection system components , operating principles and calculation method of the system parameters ; establish the mathematical model and simulation model of the system and the accumulator using MATLAB SIMULINK package for failure to plus accumulator processing accumulator system dynamic simulation , the accumulator significance for the stability of the system work ; cartridge valve two conventional structure , that spool tapered cartridge valves tapered cartridge valve and seat , the first application of computational fluid dynamics (CFD) the dedicated software Fluent post-processor software Gambit established cartridge valve three-dimensional physical model and its mesh , and then using Fluent two types of three - dimensional steady-state and dynamic numerical simulation Cartridge valve , two types of cartridge valve speed and pressure fields , and each cartridge valves under different opening velocity and pressure field changes ; the basis of the simulation and analysis of the two types of cartridge valves , cartridge valves , structural optimization, proposed two optimization model and its numerical simulation , given the results of the calculation of flow visualization and by comparing the valve seat is tapered cartridge valves cartridge valves and two improved pressure loss , flow coefficient , spool force parameter optimization results. The Zhongyuan oilfield three plants and Wenmingzhai of oilfield 's with the water injection station in the 10th field trials .
