摘要
针对井楼油田的地质特征与流体性质,开展了浅层特稠油油藏高周期蒸汽吞吐注采参数优化研究,在高周期吞吐周期、吞吐井回采水率分析的基础上,对所需优化的生产井进行精细分类,最后针对不同类别井的注采参数予以优化,确定出适合该区块的最佳注采参数.结果表明,模拟边水油藏生产周期优化、吞吐井回采水率分析,可以根据生产井的动、静态参数进行合理分类,提高注采参数优化的精确性.优化后预测衰减期油汽比较历史同期提高0.159,采用优化方案使采出程度较历史同期提高了 2.4%,油汽衰减后期比较以往同阶段提高0.113,含水率下降了 1.6%,优化取得了较好的效果,研究成果对边水条件下的浅层特稠油油藏高周期蒸汽吞吐有效开发提供理论指导.
According to the geological characteristics and fluid property of oil field well building,carry out the shallow heavy oil reservoir of high cycle huff and puff injection-production parameters optimization research,in a high cycle and cycle,huff and puff Wells based on the analysis of the recovery rate of water,the optimization for production Wells in the classification,finally according to different categories of injection-production parameters to be optimized,and determine the best injection-production parameters suitable for this block.The results show that the simulation of production cycle optimization and recovery water rate analysis of huff and spit Wells can be reasonably classified according to the dynamic and static parameters of production Wells and improve the accuracy of injection-production parameter optimization.After optimization,the predicted attenuation period is improved by 0.159 in comparison with the historical period,and the attenuation period is improved by 0.113 in comparison with the historical period.The recovery degree of the optimized scheme is increased by 2.39%,and the water content is reduced by 1.58%,with good optimization effect.The research results provide theoretical guidance for the effective development of high-cycle steam stimulation in shallow extra-heavy oil reservoirs under the condition of edge water.
