A区块开发杨大城子油层,属于特低渗透储层,基础井网注采井距大,油水井间压差逐年增大,低效井多,开发效果差。利用数模技术优选了以加密调整为主的治理对策,应用后有效改善了区块的开发效果。
Block A The Yangchengchengzi oil layer is developed. It belongs to the ultra-low permeability reservoir. The well spacing of foundation wellbores is large, and the pressure difference between oil and water wells increases year by year. There are many inefficient wells and the development effect is poor. The use of digital-analog technology to optimize the encryption-based control strategy, the effective application of improved block development.
