摘　　要：渤海海上稠油油田水平井多元热流体吞吐试验成功。通过对多元热流体增产机理的分析,建立数值模拟机理模型。用正交数值试验方法,定性定量地给出了不同油藏地质参数和注采参数对吞吐效果的影响程度及敏感性。分析表明,地层含油饱和度、原油黏度、多元热流体注入温度及注入量对吞吐效果影响显著。为现场多元热流体吞吐效果预测及现场实施方案制定提供一定指导。In the Bohai sea heavy oil reservoirs, horizontal well complex thermal fluid simulation test is sue- cessed. Through production mechanism analysis for complex thermal fluid simulation, establishing numerical simu- lation mechanism model, with orthogonal numerical test method, the different oil reservoir geology parameters are given and injection-production parameters on the effect of the stimulation and sensitivity qualitatively and quantita- tively are presented. Analysis shows that, formation oil saturation, crude oil viscosity, complex thermal fluid tem- perature and injection effect significantly. It can provide guidance for forecasting the multiple thermal fluid stimula- tion effect and making the decision.
