摘要
建立了一种应用井壁取心资料评价水淹层的新方法。该方法通过井壁取心热解分析求取目前剩余油饱和度、驱油效率等参数,评价油层水洗状况及剩余油分布,为试油射孔设计提供可靠依据。通过计算储层产水率和产油指数,综合判断油层水淹程度及产油能力,提高老油田调整挖潜效率。
This paper establishes a method for evaluating waterflooded zones using sidewall coring data.This method uses sidewall coring geochemical pyrolysis analysis to obtain the current remaining oil saturation and displacement efficiency,evaluate finely the vertical waterflooded condition and remaining oil distribution in the reservoirs,and provide evidence for the oil test perforation design.By calculating the water producing percentage and oil producing index of the reservoirs,it can determine the waterflooded degree and oil producing capability,and improve the potential tapping efficiency of old oil fields.
