方法 根据达西定律 ,从高凝油油藏的矿场生产特点出发 ,首先建立油井生产压差与井筒产液量之间的数学关系模型 ,进而通过历史拟合方法 ,建立地层压力与井筒产液量和井底流压之间的定量关系式。目的 在不停抽情况下 ,根据高凝油油井地面生产资料随时定量分析地层压力变化情况 ,既起到加密求取地层压力资料作用 ,又不因长时间停井结蜡而影响产量。结果 以国内H油区S高凝油油田B单元 8口井共 49个测压点不停抽压力加密监测方法计算 ,其结果比较切合实际 ,平均相对误差仅 1 6 7% ,可以作为重点变化单元动态分析的定点测压的辅助手段。结论 定点测压井不停抽压力加密监测方法适用于高凝油油藏 ,并可作为一种油藏动态分析中压力变化趋势预测的重要辅助手段 ,在油田矿场单元动态分析及动态调配方面具有一定的参考价值。
According to Darcy’s law, starting from the characteristics of mine production in high pour-point oil reservoirs, a mathematical model was established to establish the mathematical relationship between oil production pressure difference and wellbore fluid production volume. Then by historical matching method, Quantitative relationship between fluid flow and bottom hole flow pressure. Objective To continuously analyze the change of formation pressure according to the production data of high pour point oil well at any time without stopping the operation. It can not only play the role of encrypting the information of formation pressure, but also can not affect the output due to the long period of well shut down. The results were calculated based on 49 non-stop pressure monitoring methods in 8 wells of unit B in Unit H of S high pouring oil field of H Oilfield in China. The results were more realistic and the average relative error was only 1 6 7% Unit dynamic analysis of the fixed point manometry aided means. CONCLUSIONS The fixed-point pressure manhole non-stop pressure monitoring method is suitable for high pour-point oil reservoirs and can be used as an important aid in predicting the trend of pressure changes during the dynamic analysis of oil reservoirs. In dynamic analysis and dynamic deployment of oil field units, Has a certain reference value.
