摘　　要：采用先进的设备和技术手段，实验室模拟油藏开采条件，进行长岩心水驱油实验，对中原油田A断块挥发油油藏原油不同脱气程度的水驱油效率进行了实验研究。通过对实验结果的分析，寻找油田保持压力的界限及最佳转注时机。文中所得出的结论对中原油田A断块挥发油油藏的开发具有重要意义，并可指导同类油田开发。By using the new equipment and advanced technology,water-drive experiments in long-size coreholder were developped at the reservoir condition, and studied the water-drive efficiency for a volatile oil reservoir at the different dissolved gas condition. By analyzing the experiment data, the optimum time of water injection could be found. The result obtained from these experiments is very important to the development of A Fault-block reservoir, and of other similar volatile reservoir.
