薄互层高周期吞吐后化学辅助面积组合吞吐技术优化

Optimization of Chemical Assisted Area Grouping Swallow and Spit Technology after Multi-cycle Swallow and Spit in Thin Interbeds

针对同一区域多轮次面积组合吞吐后效果效益变差的问题,在对薄互层油藏高周期面积组合注汽效果分析及评价基础上,明确了区块剩余油分布特征。利用数模及现场经验结合方法,筛选潜力区域,确定技术政策界限并优化组合模式及注汽方式,改善了开发效果,进一步提高了薄互层稠油油藏采收率。

In view of the worse effect and benefit after multi-cycle area grouping swallow and spit in the same area,based on the analysis and evaluation of steam injection effecthigh of multi-cycle area grouping swallow and spit in thin interbedded reservoir,the distribution characteristics of the remaining oil in the block are defined.The potential areas are screened,the technical policy limits are determined,and the grouping mode and steam injection method are optimized by using the combination of numerical simulation and field experience,which improves the development effect and further improves the recovery efficiency of thin interbedded heavy oil reservoir.
