通过对鄂尔多斯盆地一低渗透 M 区块驱油用表面活性剂的界面张力、乳化能力的测试，并在室内通过物理模拟实验，主要是针对 M 区岩心基本特征，研制模拟岩心进行表面活性剂驱油实验和渗吸实验。结果表明，该表面活性剂溶液可以提高低渗岩心的微观驱油效率，且渗透率越低其提高的程度越大，渗吸实验结果说明了表面活性剂溶液的渗吸对于注入水的渗吸是有提高的作用，其主要机理是降低了油滴的流动阻力。并通过 M 区柳90-38和96-32井组注表面活性剂矿场试验，进一步说明了表面活性剂溶液对于提高原油采收率的效果。
通過對鄂爾多斯盆地一低滲透 M 區塊驅油用錶麵活性劑的界麵張力、乳化能力的測試，併在室內通過物理模擬實驗，主要是針對 M 區巖心基本特徵，研製模擬巖心進行錶麵活性劑驅油實驗和滲吸實驗。結果錶明，該錶麵活性劑溶液可以提高低滲巖心的微觀驅油效率，且滲透率越低其提高的程度越大，滲吸實驗結果說明瞭錶麵活性劑溶液的滲吸對于註入水的滲吸是有提高的作用，其主要機理是降低瞭油滴的流動阻力。併通過 M 區柳90-38和96-32井組註錶麵活性劑礦場試驗，進一步說明瞭錶麵活性劑溶液對于提高原油採收率的效果。

Through the interfacial tension and emulsifying capacity test of a surfactant for oil displacement in M area of Ordos basin, and the indoor physical simulation experiment, oil displacement experiment and imbibition experiment of the surfactant on simulated core based on core basic characteristics of M area were carried out. The results show that, the surfactant solution can improve the oil displacement efficiency of low permeability cores; the lower the permeability, the higher the enhanced degree. Imbibition experiment results show that the surfactant solution imbibition can increase injected water imbibition obviously,its main mechanism is to reduce the flow resistance of oil drop. Through the surfactant flooding pilot test in Liu 90-38 and 96-32 well group of M area, oil recovery effect of surfactants was further proved.
