摘　　要：分子膜驱油技术是目前石油业提高采收率研究的一个重要方向。其核心就是它与储层岩石接触后,由于在岩石表面的吸附、滞留和捕集作用,使储层表面的润湿性发生变化,从而达到驱替残余油、提高原油采收率的效果。例如由强亲油向弱亲油、中性,甚至亲水性变化时,不仅原油的采出程度有大幅度的提高,而且对于低渗透储层,特别是超低渗透的储层来说,也由于注入性和注入能力的提高而可以进行理想的水驱或化学驱。本文结合宝浪油田低渗储油层的实际情况通过对分子膜剂性能的评价,筛选出了适合宝浪油田低渗储层的分子膜剂类型和浓度。the molecular film drives tlhe oil technology is an important research direction to enhances the recovery efficiency at the present petroleum industry. Its core is that it causes the wettahility of reservoir surface to change by adsorption detained and trapping in the rock surface after it contact with the reservoir rock. Thus it can achieved to displacement the remaining oil and can enhances the crude oil recovery efficiency by the effective way. For example it can large scale enhance the recover degree of crude oil . moreover regarding the low seepage reservoir, specially the ultra low seepage reservoir said, it also can carry on the ideal water drive or chemistry＇ drives by enhance the injectivity and injectability. In this paper, Baolang low-permeability oil reservoir through the actual situation on the elements of the performance evaluation of the film, selected for the low-permeability oil reservoir Baolang elements of film types and concentrations.
