摘要

塔河油田底水砂岩油藏以水平井开发为主,底水能量充足,非均质性强,底水易沿高渗段点状锥进水淹,导致大量剩余油无法采出。运用数值模拟结合生产测井得出底水易延高渗段突破。在此认识基础上结合前期堵水研究,创新性地将颗粒架桥封堵与分散相携带沟通的作业有机结合,并进一步优化堵水工艺,形成油相微颗粒堵水技术体系,并在现场实践中取得较好的效果。

Abstract

The bottom water sandstone reservoirs in the Tahe Oil Field are mainly developed by drilling horizontal wells. They have sufficient natural energy of bottom water and serious reservoir heterogeneity. Bottom water cones along high permeability zones, which makes it difficult for remaining oil recovery. Applying numerical simulation and production logging data, a conclusion was drawn that bottom water breakthrough from high permeability zones easily. Furthermore, based on earlier research, we combined particle bridging plugging with dispersed phase for the first time. Oil-based particle agents for water plugging were proposed. This technique was fairly effective in field application and worth promoting.
