摘　　要：鱼骨井能够有效增加油层的裸露面积、提高油藏动用程度、扩大蒸汽波及体积,最终提高油藏采收率。蒸汽吞吐的开发效果是注采参数综合作用的结果。选取注汽干度、注汽速度、注汽压力、焖井时间、周期注汽量和最大排液量6个注采参数并考虑注汽干度、注汽速度、注汽压力之间的交互影响进行研究,采用直观分析法和方差分析法对试验结果进行分析,得到最优的蒸汽吞吐注采参数组合,依据各因素对累积油汽比的影响显著性进行排序。研究表明,交互作用对累积油汽比的影响并不显著。正交数值试验的结果可为现场鱼骨井蒸汽吞吐注采参数的优化提供理论指导,具有一定的实际意义。Herringbone wells can effectively increase the exposed area of oil layer,increase reservoir producing degree,and extend the steam swept volume,ultimately to enhance oil recovery.The throughput result of steam stimulation is mainly depended on injection and production parameters.This paper studies the effects of the six injection-production parameters including steam quality,steam injection rate,steam injection pressure,soak time,cyclic steam injection volume and the maximum lifting rate,and deal with the interaction among steam quality,steam injection rate and steam injection pressure.By using visual analysis and variance analysis on the test results,the optimal combination of injection-production parameters are obtained,and Sorted by the various factors based on the impact on the cumulative oil steam ratio.Research results show that interaction is not significant.The results of orthogonal numerical test can provide a theoretical guidance for herringbone wells injection-production parameter analysis optimization of steam stimulation in the field,and also have some practical significance.
