稳定同位素井间示踪技术在深层块状稠油油藏水驱特征研究的应用

经对冷43块深层块状普通稠油水驱注水5个试验井组开展的稳定同位素示踪测试，利用中子活化技术分析样品，采用先进的示踪剂定量分析与流动模拟相互结合的方法，以示踪数值模拟为手段，评价了油井连通、油层平面及纵向上的非均质性、隔层的封隔性等因素对水驱控制程度及动用状况的影响，通过优化注水推进方向及速度，强化动态调整措施，提高了稳产基础。

The Application of Stable Isotope Tracer Technique Between Wells in Deep-Blocky Dense Crude Reservoir During Water Flooding

According to the steady isotope tracer testing and sample analysis by using neutron activation technique to five common dense and water-flooding groups in deep-blocky layers of cold 43 blocks, a new method by using the advanced tracer rational analysis and flowing simulation is presented.By means of tracer numerical simulation,the influence of connect effect between wells, heterogeneous behavior and pack behavior on water flooding control degree and work status is discussed. By using the optimized method of water flooding direction and velocity and intensifying dynamic adjusted measure, the steady producing foundation can be improved.
