基于分层注水数学模型的油藏数值模拟
Reservoir simulation model based on stratified water injection and its application
摘要
Abstract
To improve hierarchical the disposable position and reliability of the simulation results of the remaining oil for accurate simulation of water flooding history, combined with the oilfield layered water injection data to analyze the characteristics of the faucets mouth loss, set up to consider starting differential pressure, water nozzle diameter and loss characteristics of the mouthstratified water injection numerical simulation model, layers paragraphs front of the mouth of the stratified injection wells flow pressure the mouth loss equation well-grid pressure equation coupled; consider layered the waterflood reservoir simulation linear system generates wellbore flow well-reservoir flow coupling stratified water injection reservoir simulation and stratified water injection analog functions in PBRS (parallel black oil simulator). The simulation results show that the model can reflect the role and development of mining stratified water injection effect, to alleviate the oilfield layer utilized contradiction between to improve water-flooding development effects.关键词
