摘要
在气顶油藏开发中，经常遇到油井气窜的问题。准确地计算气窜气量，对进行气顶油藏油、气开发动态分析，研究剩余油、气分布，计算天然气最终采收率及可采储量具有十分重要的意义。文章提出油藏生产气油比动态法和溶解气累积产量法计算气顶油藏气窜气量，通过实际应用，证实了这两种方法的可靠性。
A reservoir with gas cap is one of normal kinds of reservoirs,which is made up gas-bearing zoneand oil-bearing zone.Gassed-out wells are of fen encountered during developing this kind of reservoirs.Accuracy of computing gassed-out volume is very important for studying the production level of oil-gas reserves and the distribution of remaining oil-gas,laying down corresponding adjustment measure,improving developing efficiency of oil-gas and computing gas ultimate recovery factor and recoverable reserves. The dynamic method of producing GOR and the cumulative production one of solution gas for computing gassed-out volume in the reservoirs are proposed out. The reliability of the two methods are proved by practice.
