电位法监测火驱电阻率模型在石油开采中的应用

Application of the fireflooding resistivity model monitored by potentiometry in oil recovery

烧油层(火驱)是燃烧地层的一部分原油以提高稠油采收率的最具潜力的一项热采技术,但因一直缺乏对驱油机理准确的描述,该技术至今仍未形成相当工业的规模。通过电位法对工区进行监测并对结果进行反演处理,通过温度和电阻率差异识别燃烧驱油中的各区带及油气的运移方向,对油田石油开采具有一定的指导意义。

Burning oil layer(fireflooding) is a most potential thermal recovery technique that some of the oil in an oil layer is burned to improve the thick oil recovery ratio. The technique have not expanded its industrial scale up to now as it is lack of the accurate description for the oil- displacement mechanism. Through the work area monitoring with the potentiometry and the monitoring data processing with the inversion, It will provide a certain guidance meaning for the oil recovery by the identification of each of the zone and the direction of the hydrocarbon migration with the temperature and the resistivity difference in the process of the displacement of reservoir oil with the burning.
