中文摘要:    针对储量规模小、分布分散、异常高压等海上边际油气藏,油气人工运移开发方法是经济有效的开发方式,但该方法仅处于探索研究阶段,并未进行实践。为验证该方法的可行性并指导人工运移先导试验的实施,基于系统分析理论和物质平衡原理,将油气人工运移过程按照4 个节点划分3 个流动阶段:源油气藏的渗流、运移通道的管流和目标油气藏的渗流。针对不同阶段,考虑储层中油气两相渗流的影响,分别建立相应的解析模型,然后联立以上关联模型,综合运用节点分析法和油藏数值模拟法,预测不同时刻下人工运移气流量、油流量,并对预测结果进行相互验证,建立了一种油气两相人工运移流量预测方法。该方法成功指导了人工运移先导试验的实施,应用结果表明:流量预测结果与先导试验结果相对误差在20% 以内,验证了该方法的可靠性。结论认为:试验区若采用人工运移开发方式进行开发,与衰竭开发相比,预测增油3.63×104 m3,开发效果显著。
英文摘要:    As an effective and economical tool, the artificial migration method has been developed for offshore marginal oil and gas reservoirs with small-scale reserves, scattered distribution, and abnormal overpressure. However, it is still in the primary research and has not been put into practice. In order to verify its feasibility and to provide the guidance for implementing some pilot test, the artificial migration process can be subdivided into three stages according to four nodes based on many ideas on system analysis and material balance principle, including the seepage in source reservoirs, the pipe flow in migration pathway, and the seepage in target reservoirs. Considering the effect of oil-gas two-phase seepage on reservoirs, many analytical models corresponding to different stages are established. Moreover, flow rates of artificial migration at different moments are predicted by using two approaches of both node analysis and numerical simulation. And the predicted results are verified mutually. In this way, the method for predicting the flow rate of oil-gas two-phase artificial migration is established, which can provide a successful guidance for carrying on the pilot test of artificial migration. Its application show the relative error between the predicted flow rates and the test results is within 20%, which also verifies its reliability. In conclusion, compared with depletion development, this artificial migration method will be remarkable with the predicted oil increment of 3.63×104 m3 if it is applied to a test area
