中文摘要：
井间气窜现象会对稠油多元热流体吞吐井开发产生不利影响。为了减少气窜现象、改善热采开发效果，运用数值模拟技术，分析观察平面及纵向非均质性、渗透率、韵律性、注入速度等因素与多元热流体吞吐井间气窜规律的关联。通过气体窜流系数来定量表征窜流程度，并据敏感性分析结果提出降低气窜发生概率的治理措施。
英文摘要：
Gas channeling may cause bad effect on the development of multiple thermal fluid wells in heavy oil field. In order to reduce gas channeling and improve thermal recovery effect, we have studied the influence of the surface and vertical heterogeneity, permeability, rhythm and injection rate on the gas channeling by using numerical simulation technology. In addition, crossflow coefficient is defined to confirm gas channeling degree quantitatively. Measures to reduce the risk of gas channeling are proposed according to the result of sensitivity analysis of crossflow influence factors.
